Source Institutions
In this activity, learners get a closer look at the shape of a drop of water and a drop of oil. Learners first drip water onto wax paper and examine the shape of separate drops from a side view.
Paths and Ponds
Source Institutions
In this activity, learners use squares to figure out how many border tiles are needed to enclose different areas.
Boomerang
Source Institutions
Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.
