In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners make self-assembled polymer spheres.

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

This multi-part activity from the National Parks Service blends the science of plate tectonics with the culture and history of places with dramatic geologic landscapes.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.

In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this activity, learners create a freshwater ecosystem in a large plastic bottle. Learners cut and prepare bottles, then fill with water, aquatic plants, snails and fish.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

This lesson focuses on graphene and its electrical properties and applications.
