This week, we started our electricity unit. Our goal is to make three switches. We learned about batteries and how to make switches work. On Tuesday and Wednesday, I finished my first switch. I didn’t have many ideas for my next 2 switches but I eventually thought of something. On Thursday and Friday I made my second switch. My first switch works by putting down one Side of the clip which makes the other side touch the tin foil above it. For the next switch, you pull back a piece of cardboard which is connecting to another piece, pulling it back. The piece of cardboard has tin foil on it and when it is pulled, it hits a wall which also has tin foil on it, causing the two pieces to touch. I’m still thinking of an idea for my third switch.
