My Angle on Cooling: Effect of Distance and Inclination

Learners will design and conduct experiments to answer the question, "how does distance and inclination affect the amount of heat received from a heat source?" They will measure heat change as a function of distance or viewing angle.

Climate Kids: Winner and Losers In the Arctic

Arctic warming produces biological winners (whales) and losers (polar bears). This article explains why they are impacted differently and includes supplemental images.

Using Data to Understand Polar Changes

In this activity, students analyze regions of sea ice using data and ImageJ software. They measure ice mass and calculate effective albedo, and plot changes in solar energy and water/ice cover percentages. This is part 4 of a four-part activity on polar science.

Plotting the Apparent Daily Motion of the Sun

This is an activity about the Sun's position in the sky. Learners will use a clear plastic hemisphere to create a model of the sky and mark the position of the Sun in the sky on the hemisphere several times throughout the day.

Cook with a Solar Oven

Learners will build a solar oven and use it to bake s’mores. This activity is from the DIY Sun Science app and is for ages 10 and up. It requires a bright sunny day.

NASA eClips™ Real World: ICESat-2 and Earth's Cryosphere

In this video clip, viewers learn about the cryosphere - all of Earth's frozen structures including sea ice, ice caps, and permafrost. Understanding changes in the cryosphere provides scientists with valuable information about the past, present, and future of the planet.

GPM: Too Little, Too Much

This short video (4:44) helps audiences understand and appreciate the importance of measuring precipitation globally.

Hubble Deep Field Lesson Package: How Many Objects Are There?

In this activity, learners practice estimation skills as they begin to explore the Hubble Deep Field image. They first give a rough estimate of the number of objects and then follow several steps, using representative sampling techniques, to improve upon their original estimates.

Where Do They Come From? The Meteorite-Asteroid Connection

This is a lesson about the path meteorites take to get from the asteroid belt to Earth and how rare it is for the Earth to be hit by a large asteroid. Three activities comprise the lesson.
