In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this activity, learners explore the possibilities of clay as a natural material.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this sensory activity, learners enjoy the fun of a snow day any season of the year.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
