This is a booklet containing 37 space science mathematical problems, several of which use authentic science data. The problems involve math skills such as unit conversions, geometry, trigonometry, algebra, graph analysis, vectors, scientific... (View More) notation, and many others. Learners will use mathematics to explore science topics related to Earth's magnetic field, space weather, the Sun, and other related concepts. This booklet can be found on the Space Math@NASA website. (View Less)

This is an activity about the declining strength of Earth's magnetic field. Learners will review a graph of magnetic field intensity and calculate the amount by which the field has changed its intensity in the last century, the rate of change of its... (View More) intensity, and when the field should decrease to zero strength at the current rate of change. Learners will also use evidence from relevant sources to create a conjecture on the effects on Earth of a vanished magnetic field. Access to information sources about Earth's magnetic field strength is needed for this activity. This is Activity 7 in the Exploring Magnetism on Earth teachers guide. (View Less)

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 an activity about the periodic reversals of Earth's magnetic field. Learners will graph the frequency of magnetic pole reversals over the past 800,000 years and investigate answers to questions using the graphed data. This is Activity 8 in...
