Learning and caring together, building a firm foundation for the future

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.
