Getting it Just Right!


Have you ever gotten into a bathtub that was either too hot or too cold? It’s not very comfortable, is it? You can get just the right temperature for your bath by combining hot and cold water in the right amounts. In this activity, you will combine different amounts of warm and cold water, and predict what temperature the resulting mixture will be.


In this activity, you will

  • Record what happens to temperature as different amounts of warm water and cold water are mixed together.
  • Try to predict the temperature of a mixture of certain amounts of warm water and cold water.
