Potato Float

This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in buoyancy.

Weather and Climate

This background chapter reviews the basic principles of meteorology that educators need to guide inquiry activities in the classroom. Topics include structure of the atmosphere, Coriolis effect, water cycle, greenhouse effect, cyclones, anticyclones, and jet streams.

Raisin Bread Universe

In this lesson, students examine the idea of inflation in the Universe using rising raisin bread dough as a model for universal expansion.

Sea Floor Spreading

Sea floor spreading is demonstrated using a model consisting of two classroom desks and an 8-foot strip of paper. Changes in polarity are indicated using a felt marker.

Space Science Careers: Building Hinode XRT A Space X-ray Telescope

This is a DVD on the topic of science career awareness. Videos and interviews on the DVD highlight the work of those who manufacture, assemble, inspect, test, and transport scientific instruments before they are launched into space.

Climate Kids: What Can We Do To Help?

The article addresses this question by suggesting environmentally friendly actions to help reduce carbon footprints, trash production, and water usage. “Green” careers are also discussed.

The Electromagnetic Spectrum: Red Shift, Blue Shift

In this activity, a Whiffle® ball containing a battery-operated buzzer is twirled in a circle to demonstrate the Doppler effect.  The demonstration is an illustration of how stellar spectra can be used to measure a star's motion relative to Earth along the line of sight.

MY NASA DATA: Evidence of Change Near the Arctic Circle

Through an analysis of data sets on four parameters - sea ice totals, sea surface temperatures, near surface temperatures and surface type - students must decide whether the Arctic is experiencing climate change and predict any potential effects on the rest of the planet.

MY NASA DATA: Comparing Graphs of Temperature and Radiation

In this activity, students will analyze plots of temperature and radiation data to determine change over time.

Global Ocean Warming

This lesson examines the effects of surface energy transfer and storage on ocean temperatures. Included are activities that introduce the use of scientific models.
