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

In this activity, learners explore dinosaur fossils by making cast models of a T. rex. First, learners read about and research how dinosaur fossils form.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this activity, learners explore dinosaurs and fossils by creating a diorama.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this activity, learners create a biosphere in a baggie.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

In this craft activity, learners create a string of cut-out moons and stars.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this activity (page 11 of the PDF), learners investigate how quickly water moves through various materials. They measure and compare the permeability of gravel, sand, and soil.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.
