Changes of State

This week we carried out an investigation where we thought about the changes different materials go through when immersed in water. We soaked beads overnight in water and when we came to school the next day they had absorbed the water and had expanded! We realised that this was an irreversible change as the beads will not go back to their original state. We loved this investigation and enjoyed trading our beads with each other to makes lots of lovely patterns too!
