On and Off Magnet
How do you switch a permanent magnet on and off? This magnet does it, giving the students quite a problem attempting to work out how it worked. Designing experiments and using magnets and electro-magnets to try and replicate its action.

Recording the heartbeat
I am using the electronic stethoscope to record the heartbeat and then play it back amplified so that all the students can hear what the sounds are like. The students prefer this system as they can take their heartbeats away on their phones.

Balancing Equations
I used Snatoms to show how to balance equations. The students found this amusing, and it helped them understand what was going on, turning an abstract concept into a physical one.

weather sensor
I'm using the @pascoscientific weather sensor to gather weather data from ordinary days so the students can better understand averages, maxima and minima from a large dataset. Too often, students have to find an average of three or four items and we can use tools like Capstone to help.

complex numbers exponential form
Complex numbers in exponential form—Teaching complex numbers isn't complicated, but it can be hard to get your mind to think about them. Seeing numbers in graphic form helps considerably here.

Frictionless Hover balls
I'm using frictionless hover balls to help explain collisions. They are great when introducing collisions at angles and, when coupled with some sensors to show their angle and speed, invaluable for demonstrating the conservation of momentum.

microscope stage calibration slide
Using a microscope stage calibration slide to work out the measurements in the eyepiece graticule. Students seem to find it a hard concept to look at a ruler with an eyepiece graticule, then remove the slide, replace it with the subject, and be able to measure it.
