As we continue to work our way through our science curriculum, we have spent some time on worms. We have a drain system in our yard, so The Boyscout was able to dig up several dozen worms for Miss M to look at.
After examining them closely, we built a worm jar by layering sand, oatmeal, decayed matter and dirt. We put them in a dark place and observed their behavior over several weeks.
I won't say that Miss M was totally enthused with the worms (she refused to touch them), but The Bug had a great time with this experiment!
