Focus: demonstrate how insects from prehistoric times became fossilized in amber

Prior to beginning the activity, explore the process of fossilization with your kids. (some references you may want to check out of your local library in preparation include 'Usborne World History - Prehistoric World', 'Amber' by Andrew Ross, 'Dorling Kindersley Fossils', or 'Dorling Kindersley Prehistoric Life')

Amber is the fossilized resin secreted by pine trees. Just as sap from the pine trees of today (use pine cone, if available, to demonstrate the texture and appearance of sap) is sticky, insects stepping in the sap were held fast in prehistoric times. As the sap hardened, and more leaked from the tree, fossilized insects were eventually covered. The sap hardened and fossilized over time, leaving intact insect specimens for study today.

Place insect in small bottle cap. Slowly drip clear nail polish over insect. Let it dry and repeat the process. Over time, the insect will be completely encased in the hardened nail polish, just like a true amber fossil.
