This Geology unit has been so fun!
Elijah made two types of crystals for this one. He made salt and alum crystals. We set everything up that first day.
We waited about two days...
Salt:
Alum:
And then a week or more went by and we decided it was done.
Salt:
Alum:
Alum made the biggest crystals of the two.
Then it was time for inspection this evening.
They were getting the microscope out when I came to blog our fun. And I can hear OOOOOO's and AHHHHHH's coming from the kitchen. And just now Eli ran up to me to show me a drawing he has done of the structure of both. HA HA HA! I love these boys!
We learned through this that minerals will often form crystals. And that crystals are smooth, flat surfaces that meet in sharp edges and corners. We even learned of gems.
This was so good for Eli he is always picking up rocks or buying them or reading about them. :) Glad we did this one.

How fun!!! Love this post~
That is so cool!!!
So great!! Wow...you've inspired me to do this with my son. He is so mesmerized with gems and naturally formed precious stones. I think he would love this!
The Alum crystal is my favorite. I always love the look on your boys faces when they are learning. They are so involved in all that they do.
How fun! I love it!
Crystal growing is so fun!
So cool! Your crystals are beautiful. It is so neat that they are so into it!
