Animal Scent
Source Institutions
This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

Experiencing Parallax With Your Thumb
Source Institutions
In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.

Feed the Birds
Source Institutions
Learners construct a bird feeder from re-used materials. After hanging their feeder, they keep a journal about what birds visit the feeder.

Trash Traits
Source Institutions
