If you aren't already familiar with Break-Out boxes, these are an engaging way to keep your students working together towards the goal of solving the puzzles to break into the locked box.
Inside the locked box, I placed a recipe for homemade play doh to have students model the digestive tract.
This lesson contains a worksheet and answer key to break into a locked box. Each box needs 4 locks, one programmable lock with 4 digits, and three programmable locks with 3 digits. I found these locks on amazon: https://www.amazon.com/gp/product/B06Y4JXK65/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1
You are buying a two page worksheet with answer key.
