Explanation
Explanation: 

This experiment is in the process of being made but hopefully will be useful for a wide range of circuit based experiments. I've bought the following pieces to make up the components.
Opamps, transistors, capacitors, motors, solar panel, resistors, logic gates, timers, leds, diodes, thermistors, photoresitors, nickel wire heating element. I'd also like a dynamo for other power input but haven't got this yet and some links to electromag experiment.
Idea is playing with circuits and building things.
Plus aim could be an adder using logic gates, feedback devices using Opamps, fire alarm using themisotrs, light alarm,.
There'll also be places where you can clip in materials to see how conductive they are, I have some bits of wood, perspex, nickel, and bits we can see how conductive they are.

Risk assesment checked by: 
Tdwebster
Risk Assessment: 

Electrical Risk shocks, electrocution, pacemakers.
power from dynamo/battery/power supply so limit danger
first aid

heating element burns/catches fire
extinguish, run under cold water
first aid/fire policy

splinters from wooden breadboard and components
sand
first aid

component explodes (e.g. capacitor)
don't use excessive voltage/current check health of components before using
first aid

candle flame to trigger fire alarm
supervise candle while lit, don't use near flammable things, watch people's hair
first aid/fire policy

This experiment contains mains electrical parts, see separate risk assessment.
