This is an activity 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 resources are archived and available... (View More)

This is an activity about Earth's magnetic field. Learners will construct a soda bottle magnetometer, collect data, and analyze the results to detect magnetic storm events. Ideally, learners should collect data for at least a month. If several... (View More)

Audience: Middle school

This is an activity about sunlight as an energy source. Learners will create a plant box and observe that a plant will grow toward the Sun, its primary source of energy. This hands-on activity is an additional lesson as part of the book, The Day... (View More)

In this activity about the Sun's influence on plant growth, learners will create a plant box and observe that a plant will grow towards the Sun, its primary source of energy. By periodically collecting data on the growth of the plant, they can come... (View More)

This is an activity about the concept of direct versus indirect sunlight. Learners construct and use a sun angle analyzer to investigate the effect of angle on area illuminated. The fraction of light on each square of the analyzer is then calculated... (View More)

In this activity about magnetic fields and their relation to the Sun, learners will simulate sunspots by using iron filings to show magnetic fields around a bar or cow magnet, and draw the magnetic field surrounding two dipole magnets, both in... (View More)

This is an activity about ultraviolet light. Learners will make ultraviolet light detector bracelets and use them to experiment with artificial light and sunlight. Then, they experiment with various sun-blocking materials to see how such materials... (View More)

Audience: Informal education
Materials Cost: $5 - $10

This is an activity about modeling the apparent motion of the Sun as seen from Earth. Learners will use a flashlight, toothpick, and styrofoam model Sun to mimic the relative shadow motion produced by a sundial. The activity will help learners... (View More)

Audience: Informal education
Materials Cost: $1 - $5

This is an activity about the detection of magnetic storms. Learners will plot the locations of magnetic observatories in Canada and analyze the magnetic intensity for each station, looking for the difference between stable magnetic activity and the... (View More)

Audience: High school

This is an activity about the magnetic deflection. Learners will observe and measure the deflection that an iron mass causes in a soda bottle magnetometer and plot the data. The data should show the inverse-square cube law of change in the magnetic... (View More)
