After investigating ways of creating static electricity using a balloon, we now know that it happens when two objects rub together, creating an unbalance in the positive and negative electrical charges. We were amazed to see that the static electricity in the balloon was able to even pick up paper, as well as of course making our hair stand up.

Later we used our knowledge of positive and negative electrical charges, when sharing the electrical toys we had brought in from home. We understand that a plug is not always needed for electricity but that batteries can be used. We know that the battery has to be put into the toy the right way around so that the positive and negatives are properly connected. We are also aware that there are harmful acids inside batteries and so to handle them with care.

Additionally this week, we have used batteries to create our own electrical circuit to light up a bulb or sound a buzzer. We also used the correct scientific symbols to represent this in our books.
