This is an activity about the mathematics of oscillation. Using data obtained in ninth and tenth activities in the Exploring the Earth's Magnetic Field: An IMAGE Satellite Guide to the Magnetosphere educators guide, learners will plot the formula... (View More)

Audience: High school

This is an activity about observing the Sun. Learners will construct a pinhole projector to project an image of the Sun, observe and record the size of the projected image, and calculate the diameter of the Sun using the measurements and a known... (View More)

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)

Audience: High school

This is an activity about oscillation. Learners will observe, time, and graph the data of the side to side motion of the mirror used in the soda bottle magnetometer activity to determine the mirror's oscillation amplitude. This activity requires... (View More)

Audience: High school

This is a lesson about the mathematics of auroras. Learners will be exposed to the mathematical formulas that are used to estimate how much magnetic energy is available in the magnetic tail region of Earth. This is the nineteenth activity in the... (View More)

Audience: High school

This is an activity about polarized light. Learners will use a polarizing filter to build and calibrate a simple polarimeter, use the constructed polarimeter to find sources of polarized light, and measure the angle of polarization of polarized... (View More)

In this activity, learners will explore the properties of color filters and filter bandpass by observing light sources using diffraction grating and color filters and create a graph of percent transmission versus wavelength to characterize the... (View More)

This is an activity about the movement of sunspots. Learners will project an image of the Sun using a telescope, binoculars, or a pinhole projector, observe and record sunspots over the course of several days, and calculate the speed of the observed... (View More)

This is an activity about oscillation. Learners will observe, time, and graph the data of the side to side motion of the mirror used in the soda bottle magnetometer activity to determine the mirror's oscillation period. This activity requires prior... (View More)

Audience: High school

This is an activity about spectroscopy. Learners will build a spectroscope with a scale for measuring wavelength and use it to observe various light sources. They will identify spectral lines in more than one light source and analyze the collected... (View More)
