Antonia chose this science experiment from her magazine. One of the cool things about homeschooling is we actually have time to do the magazine’s activities if she wants to. My childhood memories are filled with the input of good ideas from many sources and not time to carry them out.

This is one of those experiments to make something that looks a bit like a fossil. Basically, you fill a snail shell with plaster, set it in a plaster base, then dissolve the shell with vinegar. I was somewhat dubious as to whether this would work well. Actually, the incomplete form we ended up with is probably more realistic.
