In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.

Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

In this activity, learners use candy pieces and a cookie to make an accurate model of the Sun they can eat. Parts of the delicious model include solar granules, sunspots, and solar prominences.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

In this geology activity, learners use a microscope to discover and identify the components of sand.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

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 build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity, young learners will make their own flower seed nursery in an egg carton.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

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

This activity features two connected hands-on activities about dinosaur bones.

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

In this activity, learners explore a bucket of sand and beach objects.
