Preschool: Home-Grown Science

 About a week ago, Henry and I embarked on a science journey. A much longer journey than I had originally anticipated. But, it all culminated today and we were able to see the fruits of just a few moments of labor.

I used this recipe to grow a bowl of epsom salt crystals. It looked ridiculously simple and, in fact, it was. I will say, however, that three hours is a joke. The crystals have been growing in the fridge for a week! If I had a sunny window, I'm sure our efforts would have been rewarded sooner. As it is, I didn't mind a bowl of blue mystery liquid taking up the space.

The only thing that worried me was that a smooth frozen-looking layer formed on the top after a few days. I contemplated the possibility that the whole experiment was a bust, but unexpected results are part of science, right? I couldn't help but wonder what I had done wrong, though. As it turns out, I did it just right!

We pulled it out and examined the bumpy, but smooth, layer on top. Then I grabbed a spoon and gently peeled off the top layer (not unlike the top crust of a pot pie) to find the magic hiding inside!

This is the underside of the bumpy crust. 

Even more growing from the bottom of the bowl. 

Henry was completely tickled over the crystals and I let him break up part of the crust and crystals. They are as delicate as they look. I was expecting them to be cold since they'd been in the fridge and they look like ice, but they were surprisingly neutral in temperature.

We'll pull them back out when Audrey gets home from school and let her examine them, too!

Yay, Science! Yay, preschool!
