Salt
Before I started compiling this list, I was certain that salt would end up in the top spot or two. It seems like I'm constantly pulling it out of the cupboard for one reason or another!
I bumped it down a little on this list, because I just didn't have as many activity links to share as I did for some of the contenders.
I'm sure you'll share lots more ways to use salt in science lessons! And take some time to try some of these ideas:
Salt Water Painting
Salt, Vinegar and Pennies (chemical change)
The Mistake
Should I Salt My French Fries Before or After
Float an Egg
Semipermeable Membranes
Growing Crystals
It's also really great to look at under a stereoscopic microscope, if you happen to have access to one!
