In this kinesthetic activity, students take on roles of either photons or gas molecules. Photons signal a change from visible light to infrared with a piece of folded construction paper, simulating absorption by the Earth's surface and reradiation... (View More) to space. The play is guided by flipping a coin, and students see how stochastic processes result in 70% of visible protons being absorbed and reradiated as infrared. This activity is supported by a textbook chapter, What is the Greenhouse Effect?, part of the unit, Climate Change, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

This activity is an interactive word find game with words related to comets and NASA's Comet Nucleus Sample Return mission. Accompanying text and pictures describe what comets are and why we are interested in them.

This is a legacy site for videos and animations related to the Deep Impact mission and encounter with Tempel 1. Learners can watch videos about the mission, encounter, science, and results.

This is an activity about magnetism and magnetic forces. Learners will explore objects to which a magnet is attracted or repelled and record information in a learning log. Additionally, learners will identify magnetic devices or phenomena they... (View More) encounter at home, at school, in nature, and in other locales. This is the first activity in the Magnetic Math booklet; this booklet can be found on the Space Math@NASA website. (View Less)

This is an activity about depicting the relative strength of magnetic fields using field line density. Learners will use the magnetic field line drawing of six magnetic poles created in a previous activity and identify the areas of strong, weak, and... (View More) medium magnetic intensity using the density of magnetic field lines. This is the fifth activity in the Magnetic Math booklet; this booklet can be found on the Space Math@NASA website. How to Draw Magnetic Fields - II in the Magnetic Math booklet must be completed prior to this activity. (View Less)

In this problem set, learners will calculate the parts-per-thousand measure for different scenarios, including ocean salinity as depicted in the image included. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth... (View More) Science and Climate Change. (View Less)

In this problem set, learners will analyze a graph of the reflectivity of soil and two kinds of vegetation to understand how scientists use these measures to identify different materials. Answer key is provided. This is part of Earth Math: A Brief... (View More) Mathematical Guide to Earth Science and Climate Change. (View Less)

This is an activity about depicting magnetic fields. Learners will observe two provided drawings of magnetic field line patterns for bar magnets in simple orientations of like and unlike polarities and carefully draw the field lines for both... (View More) orientations. This is the third activity in the Magnetic Math booklet; this booklet can be found on the Space Math@NASA website. (View Less)

In this problem set, learners will analyze a table of electrical consumption of appliances when not in use and consider the total consumption in kilowatt-hours (kWh), associated cost and their own consumption when appliances are in "instant-on" or...
