Year 5 have been looking at changing materials. They first learnt about solids, liquids and gasses and then had the fantastic opportunity to make and handle a material hat that is both a solid and a liquid, depending on the force applied to it.
That was definitely the best lesson so far this year in Year 5. I loved how the Ooblek kept changing from liquid to solid when I squeezed it in my hand. Jacob H, Year 5 pupil
