Eggs

Ms Druhan showed us two eggs and told us that one was raw and one was cooked. We had to figure out which was which. We named the eggs Al and Bertie! We felt them at first but we couldn't figure it out. We decided to put them in water to see if they would float or sink.  The first container was too small so we got a bigger one. They both sank! We thought about the insides of the eggs. The raw one was liquid inside and the cooked one was solid inside. If you shake something solid, it stops moving when you stop shaking it. However, if you shake something liquid the liquid keeps moving when you stop shaking. We decided to spin the eggs. When we spun the eggs and stopped them, one of the eggs kept moving and the other egg stopped. We discovered that Al was raw and Bertie was cooked. We cracked Al into a container to check if we were right. We were correct!

Then Ms Druhan asked us to try and make the egg stand. We were not allowed to hold it! We eventually decided to use salt. We poured out a mound of salt and placed Bertie in the salt. He stood up! Gradually we blew away some of the salt. Bertie managed to stay standing with just a few grains of salt holding him up. It was amazing!
