Exploring the Solar Wind and Coronal Mass Ejections

This is an activity about the solar activity cycle. Learners will construct a graph to identify a pattern of the number of observed sunspots and the number of coronal mass ejections emitted by the Sun over a fifteen year time span.

Exploring the Milky Way

As science extension activities, this book of problems introduces students to mapping the shape of the Milky Way galaxy, and how to identify the various kinds of galaxies in our universe.

Measure Up

Students will use various objects in the classroom to experiment with nonstandard measurement. They will make estimates and test them out.

Motion of the Sun and Earth: Using a Playground Model to Explore Rotation and Revolution

This is an activity about the rotation of the Earth and Sun, and the Earth's revolution around the Sun. In chalk, learners will draw the Sun-Earth system, complete with Earth's orbit, and then act out the rotation and revolution of a yearly cycle.

Rising Waters

Using a computer interactive tool, students investigate the changes in coastline that would result from a change in sea level, and suggest what factors could cause a rise in sea level.

Listening to Light

In this activity, students learn that light carries information. Students also discover that infrared (IR) radiation is a form of light that in some cases behaves like visible light and in other cases behaves very differently.

Identificando Estrellas Con Un Planisferio

This is an activity about constellations. Learners will create a simple star finder using basic materials and learn to use it to be able to identify constellations in the night sky for various dates and times.

Exploring Single Images

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

Is the Sea Level?

In this video-based activity, students learn that sea level is an average measurement of the height of the ocean, and sea level changes with the seasons and over time.

Ritter Discovers Ultraviolet

In this activity, students perform a version of the experiment of 1801, in which ultraviolet light was first discovered by Johann Wilhelm Ritter.
