Deep Sea Diver
Source Institutions
In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.
Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
Shower Estimation
Source Institutions
In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.
Building A Storm Drain
Source Institutions
In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.
Cleaning Water with Dirt
Source Institutions
In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.
Sky Floater Challenge
Source Institutions
In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
