After reading about how engineering has made adaptive devices possible for people with disabilities, pupils work in groups to discuss different devices to determine whether or not they are adaptive. They also disassemble a pair of eyeglasses in order to analyze the materials and design. This is a hands-on critical-thinking activity that you can use in a STEM or engineering unit.
- Ideal for meeting Next Generation Science Standards in engineering
- Provides opportunities for cooperation and critical thinking
- A neat, multi-toned worksheet guides groups through the analytical process
- Gathering used eyeglasses and sunglasses could pose a challenge; ask your class to bring some in to class a week prior to this lesson
- Eyeglass repair kits are not likely to already be in your arsenal of supplies, but the activity would make the cost of purchasing them worthwhile
