The Brain

 Looking at the Brain and revision, try juggling for 5 minutes between 20 revision sessions. Juggling lets some of the brain relax while working on the hand-eye coordination centre. After juggling, learning is better, and memory recall is more effective.

Inside a Laptop

 A laptop hard disk upgrade gave many students their first look inside a laptop, allowing them to find and identify the parts and compare them to the desktop version. Changing to an SSD improved the boot time of the laptop, making it usable again as well as gaining an extra TB of storage.

Testing for chemicals

 Putting on their detective hats, the students tried to determine the mystery chemical. A good, fun experiment, with the students discovering that a negative test was almost as good as a positive one in detective work. I just wish I had a Mass Spectrometer - even more fun.

Energy Conversions

Energy conversions: the Steam Engine. Chemical energy in the fuel is turned into thermal energy and then into kinetic energy. Passing down a pully for gear reduction to change from spinning to a vertical motion and powering several different devices from one. One device: so much Physics.

A level Math

 Students working out just what formulae are and are not in the exam sheet. Then, the panic can begin to memorise the formulae that are not given.

Fun with Electrostatics

 I'm having some fun with the students investigating Electrostatics. We are deflecting water, moving suspended rods, charging hair, fixing balloons to walls and ceilings, and fixing plastic and paper to windows with no glue, just some charge. Then, using amber to clean a PC fan of dust.

Elodea photosynthesis

 Finding out the best aquatic plant to demonstrate the effect of light intensity on the rate of photosynthesis using a few different plants. I have been getting the best results from Ceratophyllum demersum
