This week, our young scientists explored authentic and replica fossils as we learn more about the job of a paleontologist. In order for something to be a fossil, it needs to be at least 10,000 years old. Some of our specimens were at least 2 million years old! To learn more about how a dinosaur becomes a fossil, check out this video from the Museum of Natural History. Interested in making your own fossil to excavate? Here is the recipe we normally use to make them: 2 cups soil, 2 cups sand, 1 cup flour, 1/2 cup cornstarch. Mix in a large bowl, then slowly add 3/4 cup water (you may not use all the water). You're looking to create a mixture that is not too wet, but can stay together in a ball when squeezed. Add toy dinosaurs, sticks, stones, or seashells. Let dry for a day or two before excavating. Check out some of what we explored this week! Comments are closed.
