What are batteries?
Batteries store electricity for appliances that you can’t or do not want to plug in. Batteries can be put in and taken out of appliances. Batteries can “run out” of electricity. Some batteries can be recharged (refilled) with electricity. Each appliance has to have the correct battery to work properly.
+ and -
The + and – signs help you to know which way the battery should be inserted. If a battery is not put in correctly then the appliance will not work!!!
Making a Circuit
A circuit is a path that allows electricity to pass through it. For electricity to pass through the circuit must be a complete loop.
The electricity flows from the negative terminal of the battery, through the bulb and back to the positive terminal of the battery. Electricity always flows from the positive (+) to the negative (-)
Switches help control the flow of electricity through a circuit
Switch on
Turning a switch on closes the switch. This completes the circuit and allows electricity to flow through the lamp. 
Switch off
Turning a switch off opens the switch. This breaks the circuit and doesn’t Allow electricity to flow through the lamp.
Great Job! This would be a great experiment to do in the class. Maybe you could even use different size batteries to see if there is a difference. I'm sure there would be a great discussion following this experiment.
ReplyDeleteI really liked the visual aids that you ladies provided during your presentation. It makes it so much nicer to see the finished product in person. I also really enjoyed the drawings that you presented to introduce the topic :) Wonderful work!
