In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

In this activity, learners discover that a material can act differently when it's nanometer-sized.

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

In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
