We learned allot about the Arctic and permafrost. We learned about Russian names and how they are organized. Squirt really enjoyed the application of that one to our own family names.
The permafrost activity I modified a bit so that it was completely edible (and that means allergen free too in our house). You have to understand sweets are a controlled substance in our house. And sweets with food coloring are consumed only a couple of times a year. So if I made Jello I felt I couldn't let it go to waste covering it with real soil (as the TM suggested). So we made it edible for everyone. We crushed Pamela's Gluten Free Dark Chocolate cookies for the soil. I made strawberry Jello. (Which is edible even for my little guy with Strawberry allergies. Why? Because there is not anything real strawberry about it!) And we spread So' Delicious Coconut Milk Ice Cream over the top for the ice. Sounds weird but it really did taste good and everyone could eat it, especially Buddy.
