Lesson 1
In Lesson 2, students are prompted to design their own lens from a raw material, taking into account its intended usage, available materials, and manufacturing challenges. Again, in Lesson 5, students consider how they might use materials to manipulate light to solve a real world problem.
Included resources
5 lessons and 7 supporting media items.
