The machine consists of a speaker stripped down to it membrane that attaches to the coil. An aluminum saucer is then applied around the coil and adhered to the plastic. Spacers are then added to keep the rod steady.

The cables are then attached and plugged into an amp which is then triggered by an external source. We discovered the appropriate amount of sand to use via trial and error. This attempt was made using flour. We chose a number of sensors for use with our project-based activities. Nova Scotia. 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 school shut down, I was given a short window to collect what I could from my classroom to teach online. 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. I love to discover, produce experiments and share discoveries. I am looking forward to work with your team. While there I also started a tremendously successful new course that gave students the ability to explore their interests in science and consisted of students completing one project a month, two of which were to be hands-on experiments, two of which were to be research based, and the final being up to the student.

In I finally had the opportunity to once again teach Physics and have been working hard to build the program. Being in the vocational school for the region has led to many opportunities to collaborate with our Electronics, Design Drafting, Welding, and Photography departments on highly engaging inter-disciplinary projects.

Following this, I returned to Canada and began working with the Perimeter Institute, becoming part of their Teacher Network. These experiences and being part of professional development workshops with the AAPT and the Canadian Light Source CLS this summer has given me the opportunity to speak to many Physics educators around the world to gain new insights into how my classroom evolves.

As I work to build our program, I am exploring new ideas that see students take an active role in their learning, more inter-disciplinary work with departments in our school, the development of a STEM For Girls program in our building, and organizing participation in challenges from the ESA, the Students on the Beamline program from CLS, and our local science fair.

My first job was teaching technology courses at a local high school, a far cry from the English and Social Studies job I had envisioned myself in. I was lucky enough to stay in that position for over ten years, teaching various technology courses in grades , while also obtaining a Master of Education in Technology Integration and a Master of Education in Online Instructional Media. You will notice what is absent from my bio is any background in science. In fact, I took the minimum amount of required science courses to graduate high school.

Three years ago I switched roles and currently work as a Technology Integration Leader; supporting teachers with integrating technology into their pedagogy in connection with the provincial outcomes. All of our schools have PASCO sensors at some level mostly grades and I made it my professional goal to not only learn how to use them, but to find ways to make them more approachable for teachers with no formal science background like me!

By night I enjoy building things - robotics, my home theater, flying quadcopters and finding other geeky things to do. More About Aron Hoekstra ». For this project you'll need the following items: A large speaker I used an old 8" subwoofer - a standard speaker may also work but you'll probably end up needing to use higher frequencies than I used.

A computer to generate frequencies I used this free website - Online Tone Generator An amplifier A ny amplifier will do - you just need something that'll boost the audio signal from your computer to power the large speaker. I used a guitar amplifier.

It has a feature to take an aux-in and it worked perfectly. You may also need a 3. Sheet Metal Mine is an 18" square. I had to cut it down to this size. The only sizes I could find at the hardware stores were 12" which would have been too small, or 24" which would have just been too heavy.

Make sure the gauge steel is sturdy enough to stay straight when horizontal - you don't want it to sag or all the salt will simply fall off your plate.
