Floating Egg Science Experiment

What you need
Step by step
  • Egg
  • Salt
  • 1 Tall cup*
  • Water

    1) Fill a tall cup with about 3/4 full of water.

    2) Ask the child what he/she thinks will happen if you place the egg into the cup of water. Place the egg into the cup and watch it sink.  

    3) Take out the egg. Now add 4 tablespoons of salt into the same cup of water and stir until the salt is dissolved.

    4) Ask the child again what he/she thinks will happen if you place the egg into the cup of salted water. Place the egg into the cup with salted water. Watch what happens. It floats!

    *You can reuse the tall cup provided in the Rainbow Science Experiment)



    Though this experiment, the concept of density that the children have learnt in the Rainbow Science experiments will be further reinforced. The egg will sink in the regular tap water because the egg is denser than the water. Salt water is denser that the egg, therefore the egg will float in the salt water. Repeat this experiment with other objects in the home to find out which objects are less dense or denser than water. 

    Pique your child’s curiosity and watch their eyes flicker with wonder as they seek to understand and explore the world around them. Order your Squizzel box now, select Monthly Subscription or Prepaid Plans to get Rainbow Fun as your first box!
