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.

 

Floating Point Arithmetric Errors

 Looking at how floating Point Arithmetic errors can mean the difference in life and death as a small error in time can mean the difference between a missile hitting and missing its target. In this case, a Patriot missile, missing the missile it was sent to shoot down.

Alternative energy

Looking at alternative energy sources. Solar power and wind power, but what do we do on an airless night. Investigating Gravity storage. An easy design for the lab.

 

Reversible reactions

Investigating chemical reactions with year 8. Giving the students an opportunity to play with the bunsen burners when looking at heating blue Copper Sulfate and turning it white and then adding water to make it blue again and getting some heat back before repeating the experiment.
