About this item:
All lessons start with an engaging introduction that leads to an exciting challenge that has students asking questions, problem solving, building, testing their knowledge, and discovering areas they can improve. This process sparks imaginations and gives students a better understanding of science and crosscutting concepts. Students know the criteria for each challenge but not an expected result. Most materials needed can be found in the classroom. Available individually for each grade or in a set with all grade levels. Each is 112 pages.
