In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

April showers bring May flowers, but what do coastal storms bring?

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

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 related to climate change, learners create and explore topographical maps as a means of studying sea level rise.
