My Circuit

On Monday Room's 7, 8 and 9 went to the hall to learn about how circuit's work. We all got into groups of threes and were given a brain box kit with many different types of circuits in it. The 3 classes were very exited about this subject. When we opened the box we found a booklet full of ideas. My group decided to make a speaker circuit and it made a huge screaming noise. It was screaming like this..."WEWOWEWOWEWO!!!!!!!!!" Here is a look at what my circuit looked like and what all the different parts do.
