In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this quick activity, learners observe how wind creates ocean currents.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.
