This week for science we did an experiment with a pestle and nails. Two days ago we went into the science labs and had to get a plastic cup. When then put some plaster powder into the cups and then filled them with water. We then mixed it until it turned into a thick paste. We then put a small plastic dinosaur into the paste and then sat the cups on the side of the window. Then today when we got them back we took the plastic cup off so it was just a hard paste and then broke it out. Below are some of the pictures of us taking them apart.
