Mad Scientists in Training
Today, my "mad scientists" used our kitchen lab to make goop. The formula is to combine 1/2 cup cornstarch and 1/4 cup water, stir until it has a goopy consistency and then add a few drops of food coloring. We put the goop in a plastic bag so the kids could "smoosh" it.
If you're wondering why on earth we would make such a concoction, we did it as part of K's "Science in Action" badge for Girl Scouts. As it turns out, she wasn't the only one interested in playing with the goop :o). All of my "students" got the mini-lesson on different states of matter: solid, liquid, and gas. Funnily enough, adding the solid (cornstarch) with a liquid (water) makes something that isn't really covered by those three designations and, thus, is called goop.
