The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
Mid-Ocean Ridge Spreading
Source Institutions
In this earth science activity (page 14 of the PDF), learners use layers of closed-cell foam to create their own model of the mid-ocean ridge in order to simulate seafloor spreading.
The Watershed Connection
Source Institutions
In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.
