Grade 3/4 had an interactive lesson learning all about the states of matter – solids, liquids and gases; and identifying properties of each. We had fun learning about Ooblek (goop) with an ooey-gooey ending from sticky to solid so students could see first hand and understand the states of matter involved in this experiment.
We looked at how how solids are packed tightly together and move slightly in place, liquids are close together but they can flow and move around and gases move around freely and quickly and bump and bounce off each other. We demonstrated this as a class pretending we were particles!
See the pictures below with the fun we had getting ‘sticky’!
