Egg Experiment

After Click, Clack, Moo: Cows That Type, grab some eggs for this fun science experiment. All you need is one boiled egg, one raw egg, and a marker! Let the hypothesizing begin! 

Materials:

  1. 1 boiled egg
  2. 1 raw egg
  3. Permanent marker

Instructions:

  1. Number the eggs: #1 and #2 (make sure you know which egg is boiled)
  2. Ask the kids to feel the eggs and see if they can guess which is boiled and which is raw. Write it down! (it would be fun to have the kids vote and take a tally at each step of the experiment)
  3. Spin each egg, first on its side, then on its nose. Point out the differences in how the eggs spin/don’t spin. 
  4. Discuss which egg might be boiled and which might be raw
  5. Tell them which egg is boiled and show them that when you spin a boiled egg, it spins because the inside is solid, allowing for a consistent center of gravity, but when you spin a raw egg, it doesn’t spin for long because the inside is liquid, and center of gravity shifts, inhibiting the eggs ability to spin.
  6. For some sensory exploring, break the eggs to prove which is raw and which is boiled.
