Our new topic is electricity.
On Thursday, we used different equipment to light a bulb.
The equipment was – lightbulbs, battery pack, batteries, crocodile clips and leads and a bulb holder.
To make a circuit you needed to join up the clips and the battery pack and then join the other end to the lightbulb holder. A circuit is like a circle.
When lighting two bulbs it was quite tricky but some groups even managed to light 4 bulbs.
We are going to do more electricity this afternoon so we will report back on how we get on.
This afternoon’s update!
This afternoon we put switches and motors into our circuits. We put our lego men onto the motors and watched them spin around and around. Lots of us got a surprise when the lego men started spinning as we weren’t expecting it. Some of the lego men flew off as they were going so fast so we used blu tac to try to stick them on.
Challenges – It was really hard to turn off the bulb with the switch. We hadn’t connected the switches properly. We learned that the switch has to be inside the circuit for it to work properly. Some of us made a loop onto the circuit and it didn’t switch the light off completely.
Our next challenge was to make the motor spin the other way round. To do this we swapped the wires attached to the motor round the other way. This changed the direction the electricity was flowing through the circuit.
We really enjoy making lots of circuits with our group Evan Talyor and Grace. we found trying to get 2 bulbs light up with a motor spinning round and round with a lego man one it we thought it did not have a lot of power so next time we will have double the power with 2 battery packs joined up to it

I enjoyed learning about electricity. Me and my group’s challenge was to put two lights on and a motor at the same time. My favourite part was when we used lightbulbs, a battery pack, batteries, crocodile clips, leads and a bulb holder. We also learned about electrical symbols. At the start it was a bit hard to figure out what was what but after we watched a video about the symbols it was easier. After we knew what the symbols were we wrote all the words next to the symbols on a computer.
I had fun using the electronic equipment!
I really hope we can use it again soon.
