In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this lesson that includes hands-on activities and demonstrations, learners discover that it is the tilt of the Earth's axis (not its proximity to the sun) that causes the seasons.

Through a series of simple body movements, learners gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also abou

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

Learners use beach profile data from a local beach or online data from Ocean City, Maryland to investigate coastal erosion and sediment transport.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

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 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 discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this activity, learners explore the different heating properties of soil and water.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.
