Science Experiment

Today we did a science experiment for Science Week. For the experiment you need a paper plate, a glass and some water. We filled the glass with water to the top. Then we put the paper plate on top of the glass and turned it upside down. The water didn’t fall out of the plastic cup. This was because gravity was pushing the water down but the atmospheric pressure was pushing the plate up to the plastic cup preventing water from falling out. Then we tried the experiment with the glass half full of water. This time the paper plate fell off and the water fell out of the glass.
