Magnify That

Students will learn about magnification and how a magnifying lens works. They will examine a variety of different objects, first without a magnifier and then with a magnifier, and compare what they observe. They will practice observing details of these objects with a magnifying lens.

Exploring in 3D: Make your own 3D glasses

In this lesson, learners will construct their own 3-D glasses in order to use them on 3-D images, such as images of the Sun from the STEREO spacecraft.

In this interactive module, students can vary the comet's angle of approach to see the effect of gravity on its trajectory towards Jupiter. The speed and masses of the two bodies are held constant.

Stellar Statistician

In this interactive, online activity, students practice estimation skills as they begin to explore the Hubble Deep Field image. Students first give a rough estimate of the number of objects in the image. They then use representative sampling techniques to improve upon their original estimates.

What SImilar Physical Processes Occur on Both Earth and Mars?

Similar features exist on the surfaces of Earth and Mars. This investigation includes satellite images of five Earth features and five Martian features, none of which are labeled.

Phytoplankton Blooms and Ocean Warming

In this problem-based learning module, learners study phytoplankton blooms along the U.S. coast. Phytoplankton form the basis of the marine food web, regulate carbon in the atmosphere, and are responsible for half of the photosynthesis that takes place on the planet.

Matching Birthdays

This excercise uses "the birthday problem," a well-known probability riddle with a surprising result. It serves as a calculator exercise for students and beginning computer programmers.

SciJinks: How Does a Hurricane Form?

Hurricanes are discussed as one type of tropical cyclone; the article then describes the four stages of cyclone development. The site includes a video of Hurricane Katrina and a link to a related game.

NASA Satellite Sees Carbon Dioxide

In this problem set, learners will analyze a map of atmospheric carbon dioxide derived from satellite data. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.

Can Photosynthesis Occur At Saturn?

In this hands-on experiment, students will investigate the basic principle of photosynthesis and learn how light intensity diminishes as a function of distance from the light source. Questions help learners connect these two ideas to determine if photosynthesis could occur at Saturn.
