Boats

My kiddos started building their penny boats this afternoon. Their latest STEM project is to build a boat that can hold 25 pennies for 10s without sinking. While they did that, I got the testing tank ready. It's just an old fish tank I have in the closet. The big undertaking was finding space for it! We made room on the lab table, and miraculously, it fit close to the sink so we could swing the faucet around and fill it directly from the sink with minor modifications. We taped a funnel to the tank to direct the water in. It worked great!
