This is an online lesson associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. Outside of Solar Week, information, activities, and... (View More) resources are archived and available online at any time. This is an activity about measurements of solar activity. Learners will observe an image of the Sun and sketch major features, plot data to begin to recognize patterns of solar activity, look for long-term patterns in graphed data, compare X-ray and visible light images of the Sun to find solar features common to both sets of images, and make a prediction of what the Sun will look like in a visible light image after observing an X-ray image taken on the same day. This activity is scheduled to occur during Monday of Solar Week. (View Less)

This is an activity about the period of the Sun's rotation. Learners will use image of the Sun from the SOHO spacecraft and a transparent latitude/ longitude grid called a Stonyhurst Disk to track the motion of sunspots in terms of degrees of... (View More) longitude. Using this angular motion measurement, learners will then calculate the sunspot’s angular velocity in order to determine the rotation period of the Sun. This activity requires access to the internet to obtain images from the SOHO image archive. This is Activity 4 of the Space Weather Forecast curriculum. (View Less)

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... (View More) from the Sun that are affecting Earth's ionosphere. 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 SID data posted online: http://sid.stanford.edu/database-browser/. (View Less)

This is an activity about graph interpretation. Learners will compare, interpret, and discuss four graphs of the speed, temperature, magnetic field strength, and density of a coronal mass ejection as it swept past Earth in 1997. This is the third... (View More) activity in the Solar Storms and You: Exploring the Wind from the Sun educator guide. (View Less)

This is an activity about the solar activity cycle. Learners will construct a graph to identify a pattern of the number of observed sunspots and the number of coronal mass ejections emitted by the Sun over a fifteen year time span. A graphing... (View More) calculator is recommended, but not required, for this activity. This is the second activity in the Solar Storms and You: Exploring the Wind from the Sun educator guide. (View Less)
