In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.
