Today the children began a new topic in Science-Electricity. We had lots of discussion first about the uses of electricity and the dangers it poses. Next we investigated the vocabulary of voltage in circuits. The class explored what happens to a bulb in a circuit when more cells (batteries) are added. This was a good way to assess which children could remember how to make a simple circuit and also to see which children could put the batteries into the circuit correctly. They did really well and found out that although the bulb did get brighter as the cells were added, it could only take a certain amount of voltage (electrical push) before it got too bright and broke.
