Floating and sinking

Over the last few days we have been experimenting with different objects in the water to find out whether they float or sink. There has been some fabulous language used by the children and they have all done very well making predictions and discussing what they have found out. They discovered that not all heavy things sink and not all light things float! They also found that if you change the way you put something it the water it changes whether it floats or sinks!
