BEK Primary Kit A
Primary Basic Electricity Kit A
Light a lamp using a BEK single cell holder, one BEK lamp, a BEK Switch and two leads. Make the lamp brighter by adding a second cell holder and gently hold the lamp between finger and thumb. What do you feel? Two types of energy are produced by the lamp: heat and light. Use a magnifying glass to look at the filament inside the lamp. The filament is a very thin wire that glows white hot when electricity flows through it. Why don’t the connecting wires (leads) get hot?
Designed as a resource for the teaching of introductory electricity, these kits include well structured instructional material and robust components mounted on tough, yellow plastic bases, each with two 4mm sockets. The panels are formed into circuits by connecting them together using 4mm stackable leads.
We supply two kits, Kit A is for a group of up to six students, while Kit B contains additional items and consumables which could be issued by teachers as required. Kit B is for a group of up to 6 children.
