This is an activity about the movement, or "wandering," of our Earth's magnetic poles. The learner will explore this concept by measuring and calculating the distance the Earth's north magnetic pole has moved over the past 400 years and calculating... (View More) the rate at which the magnetic pole location has changed its position during that time. Finally, learners will use this information to extrapolate how the region for viewing aurorae may change over the next century at the present rate of polar wander. This is Activity 6 in the Exploring Magnetism on Earth teachers guide. (View Less)

This is a booklet containing 24 problem sets that involve a variety of math skills, including scientific notation, simple algebra, and calculus. Each set of problems is contained on one page.

Each set of problems is contained on one page. Learners will use mathematics to... (View More) explore space science topics related to our Sun, auroras, solar features, space weather, sunspots, and solar storms. This booklet can be found on the Space Math@NASA website. (View Less)

This is a lesson about Saturn. Learners will listen to a read-aloud of the history of Saturn discoveries. Next, they learn two reading comprehension strategies (visualizing and wondering) that they can use to become more powerful readers of... (View More) nonfiction text. Finally, students share their work with partners and the class. This is lesson 3 of 12 in the Mission to Saturn Educators Guide, Reading Writing Rings, for grades 3-4. (View Less)

This interactive, online module allows students to discover the velocity needed to escape the Earth's gravitational pull. By completing this activity, students discover how mathematics can be used to find escape velocity. Students may complete this... (View More) activity independently or in small groups.

In this interactive, online activity, bias is explored when the students decide which of several sampling methods are biased. They see how bias affects the percentage of irregular galaxies determined to be in the sample from the Deep Field. After... (View More) completing this activity students will be able to analyze and identify sampling methods that reduce bias. Student may work independently or in small groups to complete each activity. This activity is apart of the online exploration, Galaxy Hunter. Detailed teacher pages, identified as Teaching Tips on the title pages of the activity, provide science background information, lesson plan ideas, related resources, and alignment with national education standards.
