Overview

In this module, your students will explore all about sight and how it can vary. Students will also look at other senses and how animals and plants process information using their senses for survival. Researching a sunflower for inspiration, students will design a stand to make a solar panel more efficient. The module concludes with discovering how sight can vary between people.

Lessons

Focus Question: Does everyone see the same things?

Guide students in developing a class focus question about the phenomenon. Does everyone see the same things?

Discovery 1: How do our eyes work?

Students will learn how the human eye works with the brain to process sight. Students will create a model of vision. Students will bend light by making two periscope designs.

Discovery 2: How do our eyes play tricks on us and why?

Students explore how the brain processes information. They will also create their own animation using what they have learned about human sight.

Discovery 3: What other senses do we use to process information?

Students will research other senses, such as smell. Students will also learn what their pets are able to see.

Discovery 4: How do an organism’s structures help it to survive?

Students will explore what insects see and how plants attract insects. Students will also learn about the different structures that organisms have to help them survive.

Discovery 5: How can sight vary between people?

Students explore the variety and benefits of colorblindness.

Engineering Design Project: Sunflowers and Solar Panels

Using what you have learned about sunflowers, decide how to position a solar panel to maximize its efficiency, or allow it to work the best.
