First, the Yellow group investigated the objects Miss Rogan gave them. There were wires, lightbulbs and batteries.
Miss Rogan was mean and didn't tell the children what to do with the equipment, she just put them in pairs and said "investigate".
Leo and Curtis were thrilled when their lightbulb shone!
Charlie noticed that when the lights worked, the wires made a circle.
The children were given a challenge to put an extra battery in the circuit and predict what they thought would happen. They correctly predicted that the light would shine brighter because it would get more power from the extra battery.
We also discovered that when 2 bulbs have to share 1 battery the lights shine, but are not very bright at all!
Working together as a team meant that they could make this huge circuit!
The red group were up next...
Miss Rogan set them the challenge to make the light shine - there were some very puzzled faces at first but through perseverance and teamwork, Thomas and Jaiden finally cracked it!
The children discovered that although these circuits looked the same, one of the bulbs was lit and one wasn't. The only difference they could find was that the batteries had the opposite sides facing each other on one, but not the other. We swapped them around and hey presto, the light was shining.
