Magnetic Fields on the Surface of the Sun

This is a lesson about magnetism in solar flares. Learners will map magnetic fields around bar magnets and investigate how this configuration relates to magnetic fields of sunspots.

The Mathematics of Mars: I Have...Who Has?

This is a brief activity about the mathematics of Mars. By playing this matching card game, learners will gain knowledge of Mars mathematical facts and vocabulary.

Diverse Galaxies Lithograph

This Hubble Space Telescope image shows the diversity of galaxies in the universe. A huge elliptical galaxy, designated ESO 325-G004, dominates the image.

The Trail Back from Near Extinction

This textbook chapter introduces the buffalo as a keystone species, and describes the environmental impacts of its near extinction, including today’s predominance of non-native species in the Great Plains. Human activities that contribute to species extinction are addressed.

Global Energy Budget

Students will explore how energy from the sun is absorbed, reflected and radiated back into space by Earth.

The Data Downpour

The Global Precipitation Mission (GPM) collects rain, snow and other precipitation data worldwide every three hours.

Why is There a Tidal Bulge Opposite the Moon?

In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen in the demonstration is included.

Particle Man and the Photon

In this kinesthetic activity, students learn how photons may be transmitted, absorbed, or scattered. Materials required include a small ball, an overhead projector, 4 clear cups, different liquids (milk, water, black ink, grape juice), and a flashlight.

Odyssey of the Eyes: Beginning Level

In this learning activity, students create a 3D model of part of their local landscape, then make a series of observations from different directions.

Technology Teacher: Evil-doer or Do-gooder - Getting the Goods on Ozone

This article discusses the differences between ozone in the stratosphere and troposphere, and how NASA is measuring ozone using a spectrometer on-board the Aura satellite. The article includes an activity: building a spectroscope using a DVD cover and inexpensive materials.
