This resource contains ideas and brief instructions on how to build animals out of construction paper and other simple materials.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.
