Crystals...


This week the children and I did a salt study. We were able to grow our own crystal by evaporating a saturated solution of salt water in a sunny windowsill. The children were fascinated by the results, which I must say were very beautiful.  The kids learned that a crystal is an organized grouping of atoms, or molecules. Each crystal has different properties and shapes. For example, sugar crystals are oblong and slanted at the ends; salt crystals are cubic. With the use of a hand lens the cubical salt crystal formations were clearly visible.


Next week we will be doing a winter bird study. We have filled up the feeders and are eagerly anticipating our winged visitors!

Wow! Your crystals are really beautiful. I think this was a great study for your family.

Don't forget that you can submit this to the OHC Blog Carnival. I would love to share it with everyone there!
