Blockly Coding with PASCO Capstone and SPARKvue

Confidently Integrate Computational Thinking into Any Lesson with Blockly

Introducing students to coding and computer-controlled outcomes is easier than ever before with Blockly coding. Included in SPARKvue 4 and Capstone 2, Blockly offers students a new world of experimental opportunities that focus on computational thinking and data visualization. Blockly’s visual coding environment is intuitively designed to facilitate the success of new coders, while strengthening the skills of more advanced learners.

Blockly’s colored coding blocks provide students with a visual method for developing strong coding foundations. The user-friendly design allows students to simply drag and connect coding blocks that correlate with syntactically correct coding elements such as variables, commands, and loops.

Blockly within SPARKvue and Capstone is compatible with all PASCO sensors and interfaces. When students combine PASCO sensors with Blockly, they are empowered to design and execute their very own sensor experiments. Students can create code that collects sensor measurements, reports data, or controls output devices such as the Smart Fan Accessory. As they execute their code, students can visualize their data using real-time graphical displays that assist with data visualization.

Real-World Coding Activities: Computational Thinking Meets Data Literacy

The integration of Blockly into SPARKvue and Capstone gives students unparalleled control over their experiments. While developing their code, students can press the Record button at any time to execute it and receive live feedback. Students can instantly monitor sensor measurements through live graphs and digits displays that support debugging throughout their code creation process. Once students have successfully coded their sensor parameters, they can collect data in real time, store it, and use it to inform future experiments.

With an unlimited amount of coding combinations, Blockly allows students to customize and create experimental designs, determine data outputs, and use those outputs to inform future decisions. Through the integration of coding and sensor-based technology, both SPARKvue and Capstone provide a platform for the exploration of phenomena through computational thinking and data visualization.

Sample Programming Activities


Entry Level Programming with the Wireless pH Sensor

The Wireless pH Sensor is the perfect tool for introducing young learners to pH and simple programming. In this activity, students use their knowledge of the pH scale and a Wireless pH Sensor to create code that runs along with their data collection. Using a simple set of coding blocks, students can instruct the sensor to identify a sample solution as neutral, basic, or acidic. As their code is executed, live data displays communicate the code’s effect in real time. A text display will correctly identify a solution’s pH. This simple activity gently introduces students to basic programming concepts, sensor measurement, and the pH scale to instill a foundational sense of confidence and understanding in STEM.

Entry Level Programming with the Wireless Temperature Sensor

For introductory lessons, students can learn to program a temperature display and a simple text output. The goal of this activity is for students to create a program that gives instructions to cool a liquid to below 15°C. Students can monitor their live temperature reading and a text output that is temperature-dependent. In this example, the text output reads “Add more ice!” when the water temperature is above 15°C, and “Great work!!” when the water temperature is less than or equal to 15°C. The Wireless Temperature Sensor should be placed in a cup containing room temperature water. Once students have developed their Blockly code, they can execute it using the Record button. Add the ice gradually to reduce the water temperature. A successful program will display a live temperature reading and the correct text when the temperature shifts above and below 15°C.

Advanced Level Programming: Thrust with Blockly and the Smart Fan Accessory

The patented Smart Fan Accessory adds versatility to any dynamics experiment. It features numerous control features when plugged into a Smart Cart. Students can control the fan’s thrust and direction from their devices. They can also set start and stop conditions that power the fan on or off when a particular measurement, such as position, reaches a set value. Students can easily determine a parameter and immediately observe its impact on the experimental outcome, which is a powerful component of active learning.

Students can control the fan’s thrust by programming calculations based on sensor measurements. In this example, a student commands the fan to maintain a thrust of -100*[Position]. This makes the fan blow harder as the cart moves down the track, causing the cart to reverse. When the fan senses a determined measurement, the student’s code is executed, producing a physical change in the experiment and altering data collection. Students can test their code’s effectiveness, make corrections, obtain live data, and complete graphical analysis before exporting their lab for grading. This user-friendly platform is an intuitive and time-efficient method for introducing students to computational thinking without straying from standards.

Transpiration with a Potometer

Transpiration with a Potometer

Transpiration is an important concept in both biology and environmental science, especially in terms of the role it plays in the water cycle. As water evaporates from the stoma of leaves water is pulled up (due to hydrogen bonding) through the xylem from the roots which have drawn the water from the surrounding soil.

Because transpiration is essentially an invisible process, a potometer is used to measure the rate of water lost to the air. The advantages that sensor technology makes in many investigations in biology and environmental science are that it allows students to see the data in real-time while greatly improving the accuracy and significantly decreasing the time needed to capture data.

Setting up a classic potometer with a Wireless Pressure Sensor is one example of how integrating sensors can improve the data collection process. With the included Leur connectors and tubing, all you need is a plant sample and optional stand with clamps to complete the lab. Students can choose from any plants available, but three general guidelines help ensure success. Students should choose a plant with

  • a woody stem/branch that will fit snuggly into the tubing, making it less prone to crushing and easier to setup.
  • relatively soft cuticle leaves because they generally have higher rates of transpiration and good stomatal density.
  • high leaf surface area (either large leaves or lots of leaflets) per stem/branch.

Insert the plant stem into the tubing as shown, making sure there are no bubbles in the tubing and that you have a few centimeters of air between the sensor and water. This can take a few tries to get right, and having a sink or tub to submerse the tubing in will help. The cohesion and adhesion of the water along with a slight positive pressure created when connecting the sensor will keep water out of the sensor even if a stand is not available.

Potometer 1
Figure 1. Potometer Setup with Wireless Pressure Sensor

Data collection usually takes 5-10 minutes depending on the plant. For the control run (taken at room temp with ambient light) wait for a change of at least 5.0 kPa before stopping data collection. After the control run is complete, find the rate of transpiration in kPa/min using the curve fit tool and save this into a data table. Save the plants from each trial so the surface area can be calculated and the trial data normalized for comparison.

Potometer 2
Figure 2. Sample data from control run at room temperature with ambient lighting.

Calculating surface area (SA) can be done using the tried and true method with graph paper, but if you have cameras and computers available students can also use ImageJ— a free image analysis tool from the National Institute of Health. This is a powerful software and the basics are pretty easy to master. The steps for conducting area and size calculations in ImageJ can be found in this blog article or on this video. Although not part of the PASCO software suite, this is another tool that eliminates some repetitive work from the procedure and let students focus on the data and analysis that support learning.

Potometer 3
Figure 3. ImageJ program analyzing leaf SA from control trial.

When the SA is determined, add it to the data table in SPARKvue. A simple calculation provides the adjusted rate in kPa/Min/cm2. In subsequent trials, students can investigate the impact of environmental variables such as light intensity, humidity, temperature, and wind— or they can compare different species of plants.

Using the PASCO Smart Cart to Teach the Right-Hand Rule

We high school physics teachers tend to associate the right-hand rules with electromagnetism. As a student, my first encounter with a right-hand rule was when I was introduced to the magnetic field produced by the electric current in a long, straight wire: if you point the thumb of your right hand in the direction of the conventional current and imagine grasping the wire with your hand, your fingers wrap around the wire in a way that is analogous to the magnetic field that circulates around the wire.

I only later discovered that this same rule can be applied to rotational quantities such as angular velocity and angular momentum. The topic of rotation has become more important in AP physics when the program was updated from the older Physics B program. Strictly speaking, AP Physics 1 does not include the use of the right hand rule for rotation, but I have found that introducing it actually helps solidify student understanding of angular vectors.

Describing the direction of rotation as being clockwise or counterclockwise is helpful only if all parties involved have a common point of view, which is ideally along the axis of rotation. As with left and right, clockwise and counterclockwise depend on your point of view. This is why it is often preferable to describe translational motion in terms of north, south, east, west, up, and down, or with respect to a defined x-y-z coordinate system; directions can be communicated unambiguously, provided that everybody uses the same coordinate system.

It is precisely for this reason that the right hand rule can (and should) be used for rotational motion. Consider the hands of an analog clock. Assuming that the clock is a typical one, it will have hands that turn “clockwise” when viewed from the “usual” point of view, but if the clock had a transparent back and you were to view it from the back you would see the hands turning “counterclockwise!” The observed direction of rotation (clockwise or counterclockwise) depends on the observer’s point of view.

Instead of using clockwise and counterclockwise, we can describe the direction of rotation with a right hand rule: if you curl the fingers of your right hand around with the direction of the rotational motion, your thumb will point in the direction of rotation, which will be along the axis of rotation. Applying this to the above we find that when viewing a clock from the front, the rotation of the hands is three dimensionally into the clock (away from the observer), and when viewing a clock from the back side, the rotation of the hands is three dimensionally out of the clock (toward the observer). If two people view a transparent clock at the same time but one observes it from the front while the other observes it from the back (i.e. the clock is between the two people who are facing each other), they will disagree on which way the hands turn (clockwise or counterclockwise) but will agree on this direction if both use the right hand rule convention to describe the direction of the rotational motion – both observers will agree that it is directed toward the person viewing the back side of the clock.

When first learning about the right hand rule, students are often initially confused, with many students failing to grasp why such a rule is even useful in the first place. Before introducing the right hand rule I like to begin by holding an object such as a meter stick while standing at the front of the classroom. I then rotate the meter stick through its center so that the students claim that it is rotating “clockwise” when asked. Being careful to keep the rotational motion as constant as possible, I then walk to the back of the room. It’s important that the students see that at no point did I stop the rotation of the meter stick – it is still turning the same way as before, and yet at some point each student finds that they must turn around in order to continue to see it. Many students are astonished to see that the meter stick is now rotating counter clockwise from their (now reversed) point of view. This helps establish the need for a better way to describe rotation.

I then introduce the right hand rule and go through a couple of examples. Traditionally, this would have been the end of it, but last year I was able to take advantage of my newly acquired PASCO Smart Cart, which has a wireless 3-axis gyroscope (i.e. rotational sensor). The coordinate system is fixed with respect to the cart, and is printed on the cart itself, but I like to make this more visible by attaching cardboard cutout vectors onto the cart which make the axes more visible to the students while I hold the cart up for them to see. I then set up a projected display of the angular velocity of the cart along each axis simultaneously. I then ask the students how I must turn the cart in order to get a desired rotation of my choosing (i.e. ±x, ±y, and ±z).

I really like how the carts, along with the live display of the 3 angular velocity components make the admittedly abstract right hand rule so much more concrete. Seeing the display agree with our predictions makes it so much more real and is much, much better than me merely saying “trust me.” I have found that introducing and using this right hand rule with rotation has made using this same rule much more natural when using it to later relate the direction of current flow and the magnetic field.

Independent Datalogging

In logging mode, wireless sensors collect data to their onboard memory for hours, days, weeks or even months at a time without needing to be connected to a computer, tablet, Chromebook or smartphone.

When the experiment concludes, simply connect the sensor to a device running PASCO software and download all the measurements it recorded.

How much does a windshield screen affect the temperature inside a car on a hot day? Using Wireless Temperature Sensors in logging mode makes it easy to find out.

Pasco Wireless Spectrometer

The PASCO Wireless Spectrometer

Simply put, constructivism is a theory of knowledge that argues that humans generate knowledge and meaning from an interaction between their experiences and their ideas. So it follows that nothing is can be more constructivist than exploring the theoretical with real-time tools that measure the invisible. And the PASCO Wireless Spectrometer is just such a tool.

One of the most amazing things about the PASCO Wireless Spectrometer is that it does exactly what you would want it to do; show you the invisible with ease, simplicity, and leave behind a useful digital paper trail of graphs and charts. Although the main purpose of the PASCO Wireless Spectrometer was “specifically designed for introductory spectroscopy experiments” it actually goes farther than that. Much farther. Much much farther!

Chinese Teachers

This trio of teachers, two from China and one from Mongolia have limited English speaking skills, but instantly understood the iPad app and PASCO Wireless Spectrometer. Seems that light is also a universal language.

The physics and electronics behind the PASCO Wireless Spectrometer are straight forward. The output is clear and obvious. And the mobility aspect is unprecedented. In other words, it does what it should how it should. Amazing enough on its own, but in true paradigm shifting fashion the PASCO Wireless Spectrometer presents the invisible world of visible light in the magical cartoon chart we’ve seen only in static textbooks for most of our lives. It’s as if the dinosaur skeletons in dusty museums suddenly came alive and reacted to the world.

Visible light, or the light our human eyes sense and convert to electrical impulses to our brains, only encompass a tiny fraction of the electromagnetic spectrum. Wavelengths between 390-700 nanometers, or from the short blue/violet waves to the longer orange/red ones with green and yellow in the middle. Infrared waves are just a little too long for us to see, and ultraviolet ones are a little too short. Even longer are radio waves, and even shorter are x-rays. The PASCO Wireless Spectrometer has a range of 380 to 950 nanometers meaning it can “see” a little into the ultraviolet and a lot into the infrared.

PASCO Wireless Spectrometer

An ultraviolet light spikes the graph just outside the shortest wavelength we can see with our eyes.

Where this all comes together is that when the PASCO Wireless Spectrometer and various light sources are manipulated with our hands, the extended visible spectrum becomes something we can explore with the same cognitive dexterity as the microscope affords us in biology. When used in the classroom for demonstrations and explorations, the PASCO Wireless Spectrometer literally lets “humans generate knowledge and meaning from an interaction between their experiences and their ideas.” So yes, the PASCO Wireless Spectrometer is the epitome of constructivist theory into educational practice.

PASCO Wireless Spectrometer

Isaac Newton

Although Isaac Newton is credited with discovering the inner workings of visible light back in the latter 1600s, the basic concept behind a rainbow was suggested by Roger Bacon 400 years earlier who in turn drew upon the works of Claudius Ptolemy a millennium before, and even Aristotle another 300 years before that.

As a quick digression here, the Newtonian physics behind the PASCO Wireless Spectrometer has roots much more than five times deeper into the past than Mr. Newton’s distance in time is from us right now. Sorry to go all Einstein on you, but the individual colors of visible light that Newton coaxed out of sunlight with only a glass triangle, and then reassembled with nothing more than a companion prism was like yesterday.  Yet the attempts to explain the phenomena were first floated last week.

And now to think that within the palm of a student’s hand and the screen of their iPad is a gift of knowledge as great as the discovery itself. A stretch? Perhaps, but unless a scientific concept can be truly understood to the point one can make personal meaning out of the discovery, memorized facts are little more than coins used to buy grades.
Technically speaking, the PASCO Wireless Spectrometer is a battery operated spectrometer that uses Bluetooth wireless or a USB wire in order to communicate with a computing device running the necessary software. With its own built-in LED-boosted tungsten light source and three nanometer resolution, the PASCO Wireless Spectrometer provides an exceptional tool for traditional experimentation with pl
enty of room left over to inspect rarely explored specimens of light scattered throughout our lives.
PASCO Wireless Spectrometer
The operation of PASCO’s unassuming black brick puts the power of spectrometry into the hands of grade school students and Ph.D. candidates alike. While maybe not the most durable block in the scientific toy box, the PASCO Wireless Spectrometer does offer a level of simplicity (when desired) as easy to use as  glass prism and sunlight. Of course you can do much more with the PASCO Wireless Spectrometer, but you don’t have to in order to get your money’s worth. This spectrometer does so much so well so easily that it literally rewrites lesson plans just by walking into the classroom.
On a higher level, the PASCO Wireless Spectrometer can be used in chemical experiments of intensity, absorbance, transmittance and fluorescence all while using a device that, according to PASCO, has light pass through the solution and a diffraction grating and then a CCD array detects the light for collection and analysis. Sounds simple enough just like a digital prism should. Except this one gives about nine hours of service per battery charge.
In the off chance that the battery fails, it is user-replaceable. in the off chance the light burns out, it is user-replaceable. And in the likely chance that liquid from a cuvette spills into the holder, a drain hole limits the damage, and cleaning the holder is user-serviceable with a cotton swab and deionized water.

PASCO Wireless Spectrometer

A portable studio light is used to provide a background of predictable photons in order to explore the absorbance properties of various types of matter including sunglasses, polarizers, fabric, and theater lighting filters.

The PASCO Wireless Spectrometer must interface with a computer or tablet. Both Mac and Windows are supported as is iOS and Android.
PASCO also suggests using the Wireless Spectrometer for the following popular labs:
  • Absorbance and transmittance spectra
  • Beer’s Law: concentration and absorbance
  • Kinetics
  • Fluorescence
  • Photosynthesis with DPIP
  • Absorption spectra of plant pigments
  • Concentration of proteins in solution
  • Rate of enzyme-catalyzed reactions
  • Growth of cell cultures
  • Light intensity across the visible spectrum
  • Emission spectra of light sources
  • Match known spectra with references
And PASCO also provides several sample labs for plug-and-play directly into the chemistry classroom. But the really exciting plug-and-play option is the accessory fiber optic probe. With no more effort than sliding a faux cuvette into the receiving slot on the spectrometer, a meter-long fiber cord moves a directional sensor out into the wild where it can capture photons from all kinds critters. Some of my favorite animals include UV lights, filtered lightbulbs, various school lighting sources, sunlight though sunglasses, polarizers, and pretty much any LED flashlight I can find, especially the really good ones.
PASCO spectrum example
Although the screen output from the PASCO Wireless Spectrometer’s software is a graphical representation of a physical property, it takes almost no mental gymnastics to understand the changes to the graph once your mind is oriented to the display. The color-coded background and gesture-ready scaling provides an exceptionally smooth relationship with the data to the point all the hardware and software disappear leaving only the experiment and the results. And in my book, that kind of invisibility is the true measure of success with a teaching product.
When teaching the next generation about the important discoveries of the past generations, we have an obligation to use the most powerful educational tools possible. The PASCO Wireless Spectrometer is truly 100% pure constructivism-in-a-box. It turns experiences and ideas into personal meaning. Battery included and no wires necessary.

Trials Table – Coming in 2020!

Capstone Trials TableYou never take only one run in science. You take multiple runs and calculate averages. Next, you vary a parameter while holding the other constant; again, taking more runs and calculating averages. Most software data tables don’t actually allow this to be done easily.

The Capstone Trials Table was created for how data is collected in the science lab and allows for the kind of analysis students need to perform.

  • Organize your data to easily define physical relationships
  • Track variables
  • Average runs
  • Plot derived values

Capstone Mass of PendulumUsing the simple pendulum lab as an example, students will time a simple pendulum under various conditions. They will vary the mass, length, and starting angle. The Capstone Trials Table allows you to vary and keep track of experimental parameters between trials and runs taken in each trial. You can also keep track of statistics for averaged runs and experimental error.

Real-world Science

Scientists always take multiple runs and calculate averages. Next, they vary a parameter while holding the others constant; again, taking more runs and calculating averages. Most software data tables don’t support this and require data export and processing… until Capstone 2.

The Capstone Trials Table was created to reflect how data is collected in science labs. It supports the analysis students need to develop critical thinking skills and interpret the data.

With Capstone students can:

  • Organize data to easily define variable relationships
  • Track multiple variables
  • Average runs within a trial group
  • Plot derived values (such as an average of runs vs. a group parameter)

For example, in the Simple Pendulum lab, students time a pendulum under different conditions by varying the mass, length, and starting angle. The Capstone Trials Table allows you to manipulate variables and track experimental data between trials and runs. You can also keep track of statistics for averaged runs and experimental error.


Graph Pop-Up Tools

Now, whenever tools are activated, the most common actions will be easily accessible on the graph. The pop-up tools allow for easy access to tool features and options.

Exploring 2-Dimentional Motion and Vectors with Capstone’s Video Analysis Feature

Capstone includes a very powerful video analysis feature which can be used for comprehensive analysis of moving objects as well as to improve understanding.  Short video clips from your smartphone can be easily imported and analysed with a range of tools.  The movement of objects with a high contrast to a uniform background can be automatically tracked by the software.


A ball will be thrown in a parabolic arc and various tools will be used to analyze the motion.  Note that the vertical and horizontal axes have been marked and a distance of 4.00 m has been measured.  This will enable the software to translate from pixels to m:

 

As part of the analysis, the position of the ball in each frame is marked and the result is as shown below:

It is now possible to have the software generate various graphs such as position vs time and velocity vs time.

A graph of vertical position vs time is as shown below:

A graph of horizontal position vs time yields the following:

A graph of the vertical component of velocity vs time yields the following result:

Capstone also includes tools that improve understanding.  For example, in the screen below, the vertical and horizontal components of velocity are shown for the ball as it flies through the air.

To make the display less cluttered and less confusing it is possible to mark the vectors at an interval other than every frame.  Below the vectors are shown every third frame:

It is also possible to have a single vertical vector and a single horizontal vector appear and move with the ball as it goes through the air.

 

It is also possible to show the acceleration vector as shown below:

The fact that a few vectors do not point directly down is likely due to minor errors made when marking the position of the ball in various frames with a mouse.

Freezing Waves in Time!

Your students will be amazed at how the PASCO strobe light instantly and dramatically freezes the motion of a vibrating string – appearing as if it’s stopped in time.
By slightly adjusting the strobe’s frequency, the string’s frozen wave will appear as if it is moving slowly forwards or backwards. This wave freezing demonstration approaches absolute zero on the ‘cool’ factor scale!

  • Wireless Spectrometer Big Hit With Students – PASCO’s wireless spectrometer has been utilized very well by our earth science and physical science teachers. It’s an excellent piece of equipment and we have very much enjoyed its addition to enriching our classroom. It definitely brings students to a higher level of understanding wave interaction at a molecular level.

  • Excellent Smart Cart – I thought the cart was excellent. The quick sampling rate for force will be very useful for momentum and collision labs we do. I’m recommending we include this in our order for next school year.

  • Datalogging Activities are Cross-Curricular

    Throughout the province of Nova Scotia, PASCO’s probeware technology has been merged with the rollout of the new P-6 curriculum. We chose a number of sensors for use with our project-based activities. Both the functionality and mobility of PASCO’s dataloggers enable students to collect authentic, real-world data, test their hypotheses and build knowledge.

    What we find important to a successful implementation and adoption by teachers is showing that the probes are not a ‘standalone technology’. The datalogging activities are very cross-curricular and can incorporate math, english, science, and geography outcomes.

    We are excited to learn more about PASCO’s new weather sensor because our students enjoy projects where they can share and compare their data with weather stations from around the world and be part of a global community.

  • We have a large number of PASCO wireless spectrometers and love how they have improved the learning experience for our students.
