Last week, we focused on archaeology and fossils. One of our activities (based on lots of versions of this project that I found on the web) was excavating chocolate chips from cookies. I baked one pan of cookies until they were quite crisp (verging on burnt) since crisp cookies better simulate excavating from rock. After the cookies had cooled we gathered an array of tools such as tweezers, toothpicks, bamboo skewers, forks, paint brushes, and small spreaders. We discovered that excavation is hard work. Getting a chip our whole was nearly impossible for both of us. But at least we got to eat our results.
