Let's Bake a Cake for the Baker
Pupils get into groups, and are given a cake mix, a recipe, utensils, and paper and pencils. One group observes another group while they go through the process of following the recipe and making the cake. They take notes and make observations. Then, they switch. The other group observes while the first group makes their cake. An interesting lesson on performing a task and observing others who are performing a task.
