Grade 3A embarked on the first of what will be many visits to the food lab. The goal this week was to create an art and science fusion where students created their own fossil replicas as part of our science unit where we continue to explore various aspects of our earth's crust. Students started the day by heading out into the school's forest and finding an artifact that they would like to fossilize. From there, they took their items to the food lab where they made coffee dough using a mixture of used coffee grinds, cold coffee, salt and flour. Their artifacts were pressed into their coffee dough to create an imprint and the dough was left to dry overnight.
In addition to learning about how fossil imprints develop, students received first hand experience on the formation of sedimentary rocks. The coffee grinds, salt and flour represented the sediment while the coffee acted as the water that binds the sediment together under the compression of their hands . As their fossils started to dry, many students were excited to share with me how their fossil creations were transforming into stone; it was definitely one of those "aha" moments that they will always remember.....that and clean up time, but that is another story.... :)
