We read the book called Stuck where a tennis ball was lost down a hole. The girl put water in and it floated up to the top... We had some questions and wondering about what floats and what sinks. Mrs Field set up some things to experiment with and we predicted if they would float or sink. It was fun guessing and then seeing what happened! We had to fill up the container with lots of water to start with. We all had turns to test the different things. We recorded our ideas and then tested them. It was very exciting.
