Bread making activities can help students meet local and national standards for scientific inquiry, experimental design, and problem solving. In the first activity, students make and observe yeast solutions. Then they predict what might happen when the recipe is modified and conduct invesitigations. The subsequent investigations increase the level of student input and encourages students to practice the skills before using them outside of the classroom. The final assignment draws upon and expands the skills practiced in class with an at-home investigation.
