In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In ancient Chaco Canyon, the people used a "sun dagger" petroglyph to mark the passing of seasons.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

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

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).

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

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

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

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.

In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

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