Field Studies – Quality in the Wascana Watershed


With 29 watersheds in Saskatchewan, it is easy to take water for granted. Students at Dr. Martin LeBoldus Catholic High School in Regina are conducting authentic water quality assessments in the local Wascana watershed, and are gaining first hand experience in the value of protecting our water resources.

Desmond Hartney is a science teacher at Dr. Martin LeBoldus Catholic High School, and is using PASCO probeware with his students in the Environmental Science 20 course. Back in 2015 after speaking with a colleague about PASCO, Desmond decided to bolster his environmental science course with a datalogging solution that was compatible with a mixed device setting of iPads and smart phones.


Today, Desmond’s grade 11 students create their own investigations in which they test the water quality in the Wascana Creek and Wascana Lake at a number of different sites within the area. In doing so, Desmond has empowered students to gather relevant and reliable data. “Using PASCO’s Advanced Water Quality sensors, students measure the chemical indicators of the local water, such as pH, temperature, dissolved oxygen, conductivity and total dissolved solids. Students also collect water samples to take back to the lab, and use the water quality colorimeter to test ammonia, phosphate and nitrate levels within the water using the PASCO ampoules”.


According to Desmond, gathering data with PASCO probes has enabled students to obtain firsthand water quality information that can be compared to provincial standards. “With the Bluetooth technology, students have the ability to download all the data directly to their phones, which simplifies the data collection process. Students then compare their findings to the Saskatchewan surface water quality objectives and assess the health of the watershed.” “The PASCO sensors provide students the opportunity to use state-of-the-art technology that biologists would be using in the field, while also allowing students to investigate issues that they are passionate about” says Desmond. In providing his students with access to these tools, Desmond is empowering them to develop technical, science-specific, employment critical skill sets. Providing access to tools used by real scientists!

  • 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.

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

  • During distance learning due to COVID-19 school shut down, I was given a short window to collect what I could from my classroom to teach online. The PASCO wireless sensors and Smart Carts were my top priority to collect to implement distance learning. By sharing experimental data with students via SPARKVue, the sensors were pivotal in creating an online experience that still allowed students to grow with their lab skills. It was easy to record videos of the data collection and share the data with my students. They did a phenomenal job examining and interpreting the data.
