The children, and I watched Dirt! The Movie on instant view through Netflix. Apart from being from a big bang, evolutionary, and extreme environmentalist viewpoint, it's a pretty enjoyable documentary about the importance of taking care of the soil, with some cute, and engaging animation. I don't think the children are going to forget there are microbes living in the soil, anytime soon.
But, we were really looking for something that told us more about the actual make up, and development of dirt - something that would expand on our reading of Steve Tomecek's Dirt. Something, like Brain Pop's short animated video on soil, that explained in simple terms, the various layers, or horizons of soil. Brain Pop is a subscription site, but if you haven't checked it out yet, they do have a free trial.
I decided to simplify things even more for the children, with a cookie and pudding parfait style snack.
The bottom layer was sugar cookie "bedrock".
We topped that with a few smaller sugar cookies (made from the same batch of sugar cookies, just rolled into small balls, before baking), to represent a "c horizon" of weathered parent rock...
...with room for seepage of soil from "b horizon"...
...which was made by mixing the pudding "topsoil", with cookie crumb "gravel".
With a final layer of pudding...
...topped off with nuts and butterscotch chips, for a smattering of "organic material".
It's great to be a homeschooler.
