Melting Hielo/Ice Experiment

It seems like it takes a long time for the ice to melt (especially during the depths of winter)! Find out exactly how long it takes during this experiment (and make a hypothesis beforehand to see if you’re correct)!


  • Muffin/Cupcake Tin or Various Jars
  • Different Solids- a couple of options are salt, sugar, baking soda, sand, dirt, etc.
  • Ice
  • A way to tell time (stopwatch, phone, etc)


  1. Before you begin, make a hypothesis on which solid will cause the ice to melt the fastest!
  2. Add the same amount of ice (1 cube, 2 cubes etc) to each cup.
  3. Add the same amount of solids on top of each cup- if you use two scoops of salt on top of the ice in cup #1, then use two scoops of sugar on top of the ice in cup #2.
  4. Have another cup of just ice by itself- that is your control cup!
  5. Set your timer, and check on your ice cubes every 10 minutes! Note what you see as the time passes!

How this incorporates STEM:

Making a hypothesis is a part of the scientific process! It’s a way to predict the results and compare your thoughts to what actually happens!
