Lesson 3: How does the environment affect perception?

Students continue to explore factors that affect perception, moving from biological factors to social and physical environments. Students view and discuss a video clip about scientists investigating the effects of language on color perception. Next, in a hands-on activity, students collect and analyze data on how different colored lights affect perception and behaviors like the selection of red candies. Students practice visualizing and analyzing their data in graphs as part of the activity, and collect evidence for revising their model throughout the lesson.
