Super Science: Circuits
During term 5, Puffins and Barn Owls have been exploring electricity circuits.
First we made circuit bugs to explore the importance of a complete circuit using these instructions.
Here are the circuit bugs we made in class.
Then we investigated parallel and series circuits.
A Series Circuit.
A Parallel Circuit.
We found out that the brightness of the bulbs stay the same in a parallel circuit when you add more to the circuit, however they become dimmer in a series circuit.
Finally, we used our knowledge of circuits to make a maze game which included a switch.
What will we found out?
Electricity powers many devices we use every day.
Electricity is a form of energy and this energy makes things work.
Batteries have energy stored inside of them so when a battery is connected to copper wires, electricity flows from the battery along the copper wire to light up the LED light.
The path along which the electricity flows is called a circuit and for electricity to flow, the circuit must be complete.
A gap in the circuit will prevent electricity from flowing. Switches create deliberate gaps in circuits and prevent electricity from flowing.
