We got a basin and we filled it with some water.
We then got a rubber, coin, pencil and a match stick.
We made guesses for each object.
We tested them and recorded our results.
The rubber sank!
The coin sank!
Our pencil floated!
The match stick floated!
We found that a paper clip and a cork sank, but a yoghurt carton floated.
We enjoyed this experiment!
