Magnetic Storms and Aurora

Learners will plot and compare the amount of energy dissipated by auroras in the northern hemisphere with the recorded Kp index of magnetic storm severity.

Space Place: What Causes the Seasons?

This article explains the role of the tilt of Earth's axis on seasonal changes. An accompanying exploration dispels the commonly held misconception that distances between the sun and Earth are a factor. The article is targeted to children ages 10-12.

SciJinks: How Does Weather on the Sun Affect Us?

The effects on Earth of solar wind, solar flares and coronal mass ejections are discussed and presented visually in a video and several photographs. The role of satellites in monitoring space weather is examined.

Space Place: Why Is the Sky Blue?

This article explains how Earth's atmosphere scatters the light from the sun, thereby creating the blue color we typically associate with our sky. Supplementing this article is an explanation of the importance of scattering sunlight. The article is targeted to children ages 10-12.

International Space Station LABS: Technology Activity 1 Heat Transfer: Keeping Cool in Space

Learners will investigate how to build a space suit that keeps astronauts cool. This is technology activity 1 of 2 found in the ISS L.A.B.S. Educator Resource Guide.

Magnetic Poles and Pulsars

Students investigate magnetic fields in two and three dimensions, and compare the magnetic field of a pulsar to that of the Earth and other astronomical objects. This is Activity 3 of the Supernova Educator Guide developed by the XMM-Newton and GLAST E/PO programs.

Reading Strategies

Students utilize two reading strategies that can be used to understand the Cosmic Times materials, as well as other readings that may be challenging to them.

NASA eClips™ Our World: Extremophiles

These two video segments introduce students to extremophiles, organisms that thrive in conditions too extreme for most other living things.

Think Scientifically: Adventures in the Attic

This is a book about seasons. Learners will read or listen to a story about two twins, Matt and Matilda, who are tasked with creating a model of the Earth-Sun system for a science fair project.

The Magnetosphere and Us

This is an activity about Earth's magnetosphere. Using provided information, learners will determine the speed of electromagnetic radiation and the speed of material ejected from a solar flare and calculate when each will reach Earth.
