M&M Experiment

This term we are learning to think like a scientist.

Our first investigation was the M&M experiment. 
  • We observed what happen when we submerged some M&M's in cold water. 
  • First the colour dissolved into the cold water.
  • Next the white shell underneath dissolved.
  • After that the "M" on each lolly peeled off and floated to the surface.
  • Finally we were left with chocolate from the middle. 
Why did this happen?
The "M" letters on M&Ms are printed in edible white ink. The ink won't dissolve in water. When the white shell dissolves, the letters peel off and float to the top.
