Ruth has had fun doing water experiments this week. Today we saw how water has a force and pushes against the balloon when you push it into the water.
The girls collected a whole lot of things from their art room and Ruth sorted them into what she thought would float or sink.
At first almost everything that they had collected floated.
I showed them how if the lids (or peg) got filled with water they would sink. We also watched over time to see how the different types of paper absorbed water and then sank (to different levels). It did not take long for Ruth to work out what would sink and then she was able to look for a few things that she knew would go down.
