Last week, I mentioned that we learned a bit about the Solar System in general. This week we’ve been looking more closely at Earth’s long history. We’ve been going over the four major eons and looking more closely at what happened in each (Hadean Eon, Archean Eon, Proterozoic Eon, Phanerozoic Eon). At first 4.6-4 billion years ago, the Earth would have been molten. Then as the Earth cooled it went from liquid to solid. Heavier molten iron sank into the core, while lighter rock rose to the surface, cooled and became the crust. This was the activity we did as we learned about the layers of the Earth.
To get ready for this activity, I made several batches of homemade play dough.
In a pan, place the following ingredients. Cook on the stove top until the dough sticks together in one big clump.
- 1 cup flour
- 1/3 cup salt
- 1 Tablespoon cream of Tartar
- 1 Tablespoon oil
- 1 cup water
- 5 drops of vegetable glycerine (optional)
- dye — We made globs of dough in different colors for the different layers of the Earth. Be sure to add the dye before you start heating it on the stove.
Once it was assembled the kids took a knife and cut it apart. It’s definitely a visual way to see the layers of the Earth!
Be sure to check out some of the other activities we have in our 100+ page Earth Science unit!
There is another option for taking notes and discussing the Layers of the Earth — an interactive notebook activity that has recently been added to the packet:
Well, that’s about it for now. See you next time here or at our Homeschool Den Facebook page!
