Salt Water Egg Experiment - Will it Float or Sink? - 0 views

rasimmons on 24 Sep 15When you drop an egg in a glass of plain water it sinks. If you drop the same egg in a glass of salt water, it floats. This experiment link explains this. If you start class with the two glasses and the eggs and just have students make observations you could really spark some interesting conversations. I would use this in part of a density lesson. This might even be my introduction to density. It is definitely a way to grab the students attention because you almost play a mind trick on them. As a student I know this would have really captured my interest, it also sparks more exploration. What else could you add to water to get the same results?
