We've been reading about the layers of the atmosphere in "A Child's Geography," and did one of the suggested activities last week -- making the layers in a jar with flour, sugar, and cornmeal.
When we were finished, the boys asked, "Now do we get to use the ingredients to make cookies?"
That wasn't in the book -- but how could I refuse? ;)
I didn't know exactly how much flour or sugar was in the two filled jars, but I added two sticks of butter, two eggs, a teaspoon each of vanilla and baking soda, a pinch of salt, and half a bag of chocolate chips, and that seemed to work just fine. The cornmeal gave the cookies a nice crispy bite.
We called them atmospheric cookies with meteor chips!
