Geologic Principles: Law Of Cross-Cutting Relationships

We recently relative one of my favorite units- relative and absolute dating and fossils of course! Enter: play doh. This lab uses a decent amount of play doh.

I used the following recipe: 2 cups flour, 1 cup salt, 1 cup water, 2 tablespoons alum or cream of tartar, 2 https://telegram-web.online/dating-culture-in-japan.php vegetable oil, and food coloring.

Overall I made 4 batches of dough and it was more than enough to last me 5 class periods. Tip: add the food coloring to the water before mixing. Place a answer layer of play doh in the bottom of a foil cupcake liner. You can decide how many layers you want to add, the thickness of each layer, add cross cuts… get creative!
