Exploring Relationships Between Two Variables

In this activity, student teams explore the connections between parts of the Earth system by examining a time series of environmental data maps.

Cepheid Variable Star RS Puppis lithograph/Cepheid Variable Stars

This is a two-page lithograph featuring the Cepheid Variable Star RS Puppis, an example of a special class of bright pulsating stars whose light and energy outputs vary over a set period of time.

Earth's Polar Wander-the Chandler Wobble

In this problem set, learners will analyze a table of the axis location of the North Pole as it passes through Earth's surface to understand variations in the planet's rotation axis. Answer key is provided.

The Cause of the Phases of the Moon

This lesson addresses the common student misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere.

Space Place: Make Asteroids You Can Eat!

Learners will shape mashed potatoes into their own odd-shaped asteroids. They can then bake them in the oven to turn them (more or less) asteroid color, and eat them for dinner.

SciJinks: Wild Weather Adventure

This online board game involves moving a "research blimp" around the world. Advancing the blimp depends on spinning an embedded wheel and then correctly answering questions related to weather.

GPM Technology and Instrumentation: LEGO Model

This site features information about constructing a LEGO model of the Global Precipitation Measurement (GPM) Mission Core Observatory.

Climate Model

Using global data sets with monthly resolution, you will adjust variables in this empirical climate model to test the degree to which natural and human influences can account for observed global temperatures from 1979-2010.

MY NASA DATA: Comparing the Effects of El Niño and La Niña

In this lesson, students use the Live Access Server to obtain real sea surface temperature data, to create maps and line graphs, and to make comparisons and conclusions about the effects of El Niño and La Ninña.

GLOBE Contrail Chart

This identification chart is a basic guide to observing contrails. It shows examples of the three types of contrails: short-lived, persistent, and persistent spreading. The chart is intended for use by students participating in the GLOBE program.
