Today we're doing a little chemistry: combining acetic acid and calcium carbonate to make carbon dioxide. It's not as hard as it sounds; just drop an egg in a jar of vinegar! The vinegar (acetic acid) combines chemically with the part of the egg's shell that makes it hard (calcium carbonate) and lots of bubbles appear (the carbon dioxide). When you're done-- just let it sit in the jar overnight-- voila! A rubbery egg. Yesterday I hit our local Goodwill store where I find more homeschooling supplies than I ever thought possible, and I found a set of boxed Berlitz for Kids Spanish books with tapes! I was really excited until I got home and found out one of the tapes was actually a Winnie-the-Pooh story tape... Well, atleast I have one complete set. It's supposed to be another HOT day. We haven't been doing the archery I thought we would practice this week, mostly because I don't want to be outdoors in the heat and the dust and the flies... |
