Egg Experiment

In Akeake we have been learning about floating and sinking. Mrs Wright did a really cool experiment with Rooms 8, 9 and 10. She had three cups filled with water, and three eggs. She put the first egg into the first cup and it sank to the bottom. In the next cup, she mixed 4 teaspoons of salt into the water and the egg floated. When she diluted (add more water to) the salty cup, the egg began to sink again. This led to a discussion about the Dead Sea and how people can float in the water because there is so much salt (it is dense).
