Fifth Grade Physical Science Activities: The Incredible Flexible Egg Experiment. In this experiment, a hard-boiled egg will fit through an impossibly small opening with the help of only a few matches. Your child will be amazed, and you'll be teaching her how seemly impossible acts are anything but—with the help of a little science!
DIY Naked Egg- use to show chemical reaction (dissolves calcium carbonate shell), semi-permeable membrane, osmosis, (equalization of water concentration). Very cool when osmosis is shown using food coloring to prove to students that the water is actually passing through the semi-permeable membrane of the naked egg.
