Modeling Mass in the Solar System and a Galaxy

In this activity, students will discover how mass is distributed in the solar system and a galaxy by using kitty litter. Students compare the distribution of mass in a solar system to the distribution of mass in a galaxy.

Understanding Decimals

This is a set of one-page problems about the sizes of moons in the solar system. Learners will use decimals to compare the sizes and distances of Saturn's moons to the center of Saturn.

NASA eClips™ 4D Guide Lites: Ozone Spotlite Interactive Lesson

The student-produced introductory video presents two common misconceptions related to the ozone hole. The accompanying lesson uses the 5E and the Frayer model to develop student understanding of ozone and ozone holes.

Solar System Scale and Size

Colored beads and string are used to create a model of the solar system in order to explore size and distance relationships among planets. A second model for comparing planetary sizes uses common types of fruits and seeds(either actual fruits or the drawings that accompany the lesson).

Why is Summer Hot?

This activity, effective outdoors or indoors, demonstrates how insolation is affected by latitude by using a pair of thermometers, each taped to some cardboard, placed outside on a sunny day. A globe can also be used, outdoors or indoors.

SciJinks: The Bad (Weather) Joke Machine

This interactive cartoon game generates weather jokes and puns. SciJinks is a joint NASA/NOAA educational website targeting middle school-aged children and their educators. It explores weather and Earth science through articles, videos, images, and games.

MY NASA DATA: Trends of Snow Cover and Temperature in Alaska

In this data analysis activity, students will obtain snow cover and surface temperature data for a locale in Alaska, plot the data, investigate seasonal trends in snow cover, and the relationship between snow cover and surface temperature at that locale.

Carbon Dioxide Changes During the Last 400,000 years

In this problem set, learners will analyze a graph of carbon dioxide concentration in the last 400,000 years and consider the rise in carbon dioxide of the last 150 years. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.

Moon over My Town

In this activity, community members of all ages are invited to contribute photographs - taken with cell phones, film cameras, or more sophisticated equipment - of the Moon. The images are collected over the course of a month or more and posted in chronological order.

What the Doppler Effect Tells Us About Distant Stars and Planets

In this demonstration, students experience the Doppler effect for sound. Students can compute the frequency change for motion along the line of sight (LOS) and determine the vector LOS component for motions not exactly on it.
