Ice Salt Science

You know how some mornings the kids wake up still tired and all they want to do is snooggle on the couch and lay quietly while you rest your eyes just a bit longer? Yep, me neither. This morning they woke up bright eyed and bushy tailed ready to start the day...immediately. So, after breakfast I took out some glass bowls, ice cubes, salt and colored water. We did this experiment in my toddler class last week and the kids LOVED it!! And it's super easy to prepare.

What you need:

  • glass bowls
  • water and food coloring
  • table salt (we also used rock salt)
  • small spoons and/or droppers
  • ice cubes (we used Super Dad's cocktail ice balls. They are much bigger so they melt slower)
  • plate or tray
What to do:
  1. Set out the bowls with colored water and one with salt
  2. put the ice cubes on a tray or plate so they don't slip and slide away. 
  3. Then leave the activity open ended! My kids first sprinkled the salt on the ice and we talked about the salt reacted with the ice by melting it. Then they dripped the colored water on the salt, changing the colors! Your kiddos might choose to start with the water then add the salt, and that's okay, too. Keep in mind there is no right or wrong way to do this experiment! Just let them explore, and let them come up with their own way to expand on the experiment :) 

They started out by spooning the salt on the ice cubes

Then they dripped colored water on the salted ice

We talked about what was happening to the ice
when the salt sat for a bit.

Busy started adding salt to the water...
 and tasted it to "see if it tastes like the ocean."

I think Beansie got a little impatient and decided
to put the ice in the water to melt it faster. 

And we discussed how oil and water or food
coloring don't mix.
Then the Beans asked if he could add food coloring
to oil instead of water...

This kind of activity is great for building new science vocabulary and for fine motor practice. And after the experiment is over, have them wash the dishes ;)
