Why Is Earth Called the "Water Planet?"

Comparing the amounts of land and water on Earth's surface leads students to discover why it is called the water planet.

Electricity and Magnetism

This is an activity about electromagnetism and the Sun. First, learners will do a KWL activity using six vocabulary words. Next, they will build an electromagnet and investigate how it works.

Discover the Solar Cycle

This is an activity about the periodicity of the solar cycle. Learners will calculate the number of M-class solar flares as a percentage of the total number of X-ray solar flares and graph these results as a function of time.

SciJinks: Saved by a Weather Satellite

This short video illustrates the fundamental role that weather satellites play in search and rescue efforts. SciJinks is a joint NASA/NOAA educational website targeting middle school-aged children and their educators.

Sulfur Dioxide: Its Role in Climate Change

In this problem-based learning activity, learners investigate impact of sulfur dioxide on the environment. Sulfur dioxide comes from both human activities and natural sources. Burning coal and other fossil fuels is the largest source of sulfur dioxide from human activities.

Comet Tails

This activity features real images of comets and challenges students to identify the different types of comet tails shown. It is an assessment activity that is based upon what students observed about comet tails in the activity Make A Comet.

The Adventures of Amelia the Pigeon

This interactive website engages children in a story-based scenario that emphasizes concepts of remote sensing and how NASA scientists use satellite imagery to better understand the Earth's environmental changes. The story features a pigeon named Amelia and is set in New York City.

Modeling Hot and Cold Planets: Activity B Experimenting with Computer Models

In this activity, students pose several hypotheses for what will happen if you continue heating or supplying energy to the hot and cold planet models (Mercury, Mars, Venus, and Earth) and then test their hypotheses using a spreadsheet based radiation balance model.

Supernova Explosions

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star. They are then introduced to the life cycle of a star and how a star's mass affects its process of fusion and eventual death.

Properties of Fresh and Sea Water

This is a hands-on lab activity about the properties and states of water.
