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:
- Set out the bowls with colored water and one with salt
- put the ice cubes on a tray or plate so they don't slip and slide away.
- 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 ;)
