Students use a dipole magnet and compass to model and map Earth's magnetic field. They then induce a magnetic field to represent a Ring Current in order to observe the response to a fluctuating electric current caused by a solar storm. The lesson...

This is an activity about how the Sun can affect the Earth's atmosphere, specifically the ionosphere. Learners will use real data from a Sudden Ionosphere Disturbance Monitor, or SID Monitor, to identify the signatures in the graphed data that can... (View More) be used to determine the times of sunrise and sunset. Although the SID monitors are designed to detect SIDs caused by solar flares, they also detect the normal influence of solar X-rays and UV light during the day as well as cosmic rays at nighttime. There is a distinct shape to a 24-hour SID data graph, with unique shapes, or signatures, of the graph appearing at sunrise and sunset.This activity is part of the Research with Space Weather Monitor Data educators guide. Use of and access to a Stanford Solar Center SID monitor and the internet is encouraged but not required. Locations without a SID monitor can use sample data provided in the educators guide.

This is an activity about identifying solar flares. Learners will cross-reference data collected from a Sudden Ionosphere Disturbance, or SID, Monitor, the GOES solar catalog, and SOHO spacecraft images of the Sun to identify solar flares coming...

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 auroras and the scientific terminology used to describe them. Learners will read an article that provides an introduction to specific terms and concepts related to auroras and auroral substorms and examine photographs of a...
