Lever Arm Balance

 Using a lever arm balance to work out moments - Immediate readout of the correct answer.

Testing for Gases

Testing for gases. A student came to me and asked what were the tests for gases. She had had a school lesson but hadn't done or seen a demo. We tested for oxygen, hydrogen, carbon dioxide and Chlorine. She now knows the tests.

 

Reflective smartcart addon

 Using the @pascoscientific smartcart with a bigger back end improves the results when measuring distances and velocities are greater distances

Matricies

 Working out matrices in Further Maths using a calculator to help with some number crunching.

Lenses and ray diagrams

Learning all about ray diagrams and convex and concave lenses. Relating what we learned about refraction and applying it to the shapes of lenses and measuring their power. The students find it difficult to apply knowledge from one thing to another.

 

The Eye

Understanding how the lens in the eye works is made a bit easier by this @pascoscientific lens; fill it with water and then use the syringe as the muscles to turn the lens from convex to concave. Place in the model eye to observe the results.
