Teacher Centered. Solution Oriented. Technology Based.

Untangle Your Circuits!

Making the leap from circuit diagrams to functioning circuits has never been so clear or intuitive. Circuits can be easily built and tested enticing students to more thoroughly explore the behavior of electricity. Your students will no longer be frustrated trying to trace out the electrical pathway through a nest of wires.

Supports inquiry learning – circuits can be easily modified and be quickly swapped out and rearranged

Compatible with both traditional and computer based labs – works with PASCO’s sensors as well as traditional Volt and Ammeters

Classroom management is a breeze – Storage is made simple with the included
Grattenels case and nesting trays

  • The 8 cm by 8 cm modules ensure that all students in a group can clearly see the completed circuit
  • Physical Components (resistors, batteries, switches, etc.) with identifying electronic symbols are visible on the surface of the modules
  • At a glance errors in a circuit can be quickly found without checking each connection

The Basic Kit includes enough modules to do 5 basic experiments:
  • Ohm’s Law
  • Series/Parallel Circuits
  • Batteries & Bulbs Circuits
  • Switches/Open/Closed Circuits
  • Electric Power & Energy

The Advanced Kit includes the Wireless Current & Voltage Sensors and modules for 7 additional experiments:
  • Kirchoff’s Laws
  • Electromagnets
  • Electromagnetic Induction
  • RC & RL circuits
  • Variable Resistance
  • LED Circuits
  • Electric Motors

Rhonda & Craig Invade LA – NSTA 2017 Recap

We were thrilled to attend this year’s NSTA national conference in Los Angeles.

Our first destination was the exhibit hall where PASCO had a very lively booth with several interactive displays.  By far the biggest hit  was the ‘Match Graph’ challenge with a super-sized Smart Cart.  Who knew that learning could be this much fun!  Check out the video to see my less than stellar attempt.

PASCO’s booth was fun, however, the real action was in the teacher facilitated workshops.  In total PASCO had 20 unique hands-on sessions that were over flowing with enthusiastic teachers.  Time didn’t allow us to see all the sessions, but we did manage to squeeze our way into a very energetic session on the new Modular Circuit Kits.  Teachers had a great time ignoring instructions and spent most of the session designing their own unique circuits – obviously investigative learning is not just for students.

We were also fortunate enough to get a seat at PASCO’s workshop session on climate change.  The session featured several hands-on modeling activities, including an investigation where teachers used the Wireless pH sensor to monitor the mitigating effects of natural buffers on acid rain.  The biggest hit of the session was seeing PASCO’s new Wireless Carbon Dioxide sensor in action.  Teachers were excited to discover that a reliable, practical and affordable way to measure CO2 has finally arrived.

Over the next week we’ll share some more videos on our adventures at the conference.

Test the Rainbow! Understanding pH

Students often struggle understanding pH. While we can tell them that it is a logarithmic function, students are more likely to associate “logs” with a calculator button or a piece of wood. So how do we get them to understand what the pH scale really means? Look for a lesson, instead of a pot of gold, at the end of a rainbow.

Let’s start with the acids. First have the students pour 10 mL of 0.1 M HCl into a test tube. Using graduated cylinders and pipets they can add 1 mL of that solution to another test tube with 9 mL of water making a 0.1 M solution. They should repeat the process of taking 1 mL of the previous solution and adding 9 mL of water until there are 5 solutions. They won’t know it, but they just performed a serial dilution. Now they can add some universal indictor to the solutions for a splash of colour.

Indicators are nice, but they really are just an indicator. In this case the indictor was not able to distinguish between the first four test tubes. (Note to self: get some new universal indicator!). Since the true colors aren’t shining through, it’s important to remember that to really understand pH, your students need to take actual pH measurements.

Now comes the pHun part! After recording the data for the solutions, it is important for students to try to make some meaning out of those measurements. Time to dust off those concentration calculation skills. They should be able to calculate the concentration, and write the concentration of the acids in scientific notation.

No need to travel somewhere over the rainbow, all your students need now are some good guiding questions and they should see that pH is primarily based on the negative exponent of the concentration of H+.  With this understanding, pH=-log[H+] can be something more powerful than just a formula to plug and chug in calculator.

 

You can even extend this activity to pOH and its relationship to pH if you drop the base. Following the same procedure, students can perform a serial dilution starting with a 0.1 M NaOH solution.

 

After this colourful and engaging activity with the Wireless pH sensor and some fresh universal indicator, your students will be able to find the rainbow connection:  a better understanding of the pH scale, what it means and how it’s measured.

Introducing PASCO’s New Wireless CO2 Sensor

Introductory Pricing: Save 10% on Wireless CO2 Sensors until April 30, 2017.

The ability to easily and affordably measure CO2 levels is great news for Biology and Environmental Science teachers.

PASCO’s new Wireless CO2 Sensor communicates directly with a wide range of Bluetooth equipped computers without requiring an expensive interface.

Ambient environmental Carbon Dioxide levels are typically very low. This means any experimental changes to CO2 levels tend to be significant in percentage terms providing convincing and reliable evidence of the phenomenon being studied.

Investigations based on the wireless CO2 sensors are easy to setup and they work.

Other opportunities for CO2 investigations include:

  • Cell Respiration
  • Photosynthesis
  • Metabolism of cold blooded animals
  • Enzyme activity
  • Fermentation
  • Indoor & Outdoor CO2 levels
  • Pollution
  • Decomposition
