On the last day of the term we had a science fair. Around about half of the term had been spent working hard for our projects for science fair. My group did tsunamis. We had to do research tsunamis and make an experiment that involves tsunamis. Next we got a tray, a flat piece of cardboard, a mountain of sand, water  and a shield with cardboard. Then we used the pieces of cardboard to make a tsunami by pushing the water.

We found out that cardboard is not a good shield
