An extra activity for our Mars lesson. We had to cut up steel wool into very small pieces. Obviously whoever wrote the instructions hadn’t done it themselves. It’s very hard to cut into tiny pieces, it all just wants to clump together. We did our best to break the pieces apart (while wearing gloves) and stir it through the sand.
One pan we kept dry, the other we poured enough water into to wet all the sand, but not flood. (That’s chicken pox all over Skeeterbug’s neck and face. Because I’m a mean homeschool mum who made him keep doing his schoolwork. He wasn’t sick, just covered in spots!)
We had to keep the wet pan wet and check it in a week. Here’s what we saw.
Definitely red. The steel wool rusted and everything turned red.
This was an extra activity from the notebooking journal. So is there steel on Mars?!? I don’t think so, but they have found iron there, and apparently scientists believe Mars has gotten its red colour from rusting iron. Anyway, Skeeterbug learned that steel (and iron) can rust and when it does it turns a reddish colour.
Science done for the day!
