More Science Experiments

This past week we also learned about minerals, including crystals. We made salt crystals which turned out very tiny (almost microscopic!). Another project was to make rock candy.... but sugar crystals take a long time to form. (We've been waiting for over a week.)
In the meantime, I found some other crystals to make...using Borax! (I'm not sure what chemical in Borax is so reactive, we've used Borax to make slime before too. Powerful stuff.) These crystals formed overnight! It's always exciting to see such dramatic results in a short period of time.
Aren't they pretty?

They're beautiful:) Much better than worms!

That's neat! You wouldn't believe how many people come in Food Lion late in the evening looking for Borax. They always ask and I say
"you have a science experiement due tomorrow, don't you?"
The answer is always "yes"!!
What fun!!
