We talked about liquefaction and how it was a solid made into a liquid by the earthquake. Then we discussed sand and how it can change when water is added. So we decided to try an experiment.
We took 2 cups of white powder and a little food colouring and added 1 cup of water. It looked like a liquid but when we stirred the mixture it felt more solid. When we touched it our fingers felt funny. Next we tried to see if objects could sink or float in it.
Then we designed a rocket that could land on a planet made out of this mixture. We used the results of our floating and sinking experiments to choose the most suitable materials for our rocket.
