Experiment 1: We put different types of rocks in to three piles that were called Igneous, Metamorphic and Sedimentary. Igneous comes from a volcano. Metamorphic is heat and pressure and Sedimentary is a mixture of conglomerate, fossils and layers.
Experiment 2: We put chalk and 3 spoons of sand into a cup and shook it really hard. Some of the sand turned pink which was the colour of the chalk. It also became softer and smaller.
Experiment 3: Our group had a bag of crystals and then we put some water in the bag, then we left the bag for a few minutes and then we came back and it was slush.
Experiment 4: Our group had a piece of paper and a tub of water and a cup of salt. We put a little bit of the paper into the water with the cup of salt and then we waited a little while and then we came back and the water had spread to the top of the paper.
