Source Institutions
In this activity (on page 2 of the PDF), learners use art supplies to build models of insects, both real or imagined.
Dinosaur Homes
Source Institutions
In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.
Yeast Balloons
Source Institutions
