Welcome to our report about when Clydach Primary School learned about electricity and simple circuits. On February 14th in Clydach Primary school, year six made simple circuit with Mrs. Ware. We could only do it with 5-6 people in each group.
The circuits we made were parallel circuits and a series circuit. This helped us learn about the use of electricity. For example, a series circuit would be used for Christmas tree lights, while parallel circuits are used as house light.
When you make a complete circuit, something called electrons travel through the wires as you can see in the animation created by Zak, Jenson and Reece. The battery is like your heart pumping blood around your body. The electrons power the bulb and the bulb lights up.
When your setting it up, it can surprise you how scientific the lights work and how people make it work. To make a simple circuit we needed wires, a battery and a bulb.
We also carried out an experiment about adding more bulbs to a series circuit; would the bulbs get lighter or dimmer? Almost everybody in the class thought that it would get dimmer and it did, in fact, go dimmer.
It did because there is only a certain amount of electrons in a battery and when you add more bulbs they have to share the electrons out. However, it is not evenly shared in a series circuit, because the first bulb in a series takes most of the electrons and gives the other bulb less and so on.
In a parallel circuit, each mini circuit has the same charge, each electron is carrying the same amount of energy. So the electricity across each wire of the parallel circuit will be the same because the voltage doesn't depend on the number of electrons in each branch.
Year 6Mc class in Clydach Primary School. There are 21 girls and 13 boys.
