Floating Egg Science Experiment
Use this floating egg science experiment for preschool (and older kids!) themes with birds, eggs, Easter, nature, and more! Science projects with children are so much fun! Simple Supplies: cup or beaker raw, uncooked egg water salt Easy How-To: 1- Ask your child if an egg will float or sink. Carefully set the egg in a cup full of water. What happened? (It should sink! Eggs do have an air space inside that grows as the egg ages. A particularly old egg may actually float, but this is rare.) 2- Can you make it float? Add a tablespoon of salt and stir until it is dissolved. Try the experiment again. Continue adding a tablespoon of salt until your egg actually floats. The egg in the picture above only took two tablespoons. What Happened? and Variations: Adding salt changes the density of the water. The egg's density does not change. When the water is more dense than the egg, the egg will float. Try the science experiment with a boiled egg and/or
