Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. The...

Learners will build and decorate their own spectrographs using simple materials and holographic diffraction gratings. After building the spectrographs, they observe the spectra of different light sources. Requires advance preparation to spray-paint...

This is an activity about vectors and velocity. It outlines the addition and subtraction of vectors, and introduces the application of trigonometry to describing vectors. The resource is designed to support student analysis of THEMIS (Time History... (View More) of Events and Macroscale Interactions during Substorms) Magnetometer line-plot data. Learners will complete worksheets consisting of problem sets that allow them to work with vector data in magnetic fields. This is activity 15 from Exploring Magnetism: Earth's Magnetic Personality.

This is an activity about Earth's magnetism. Using polar coordinates and several sets of provided information, learners will plot the position of the magnetic north pole to investigate its movement over time. This is the sixth activity in the... (View More) Exploring the Earth's Magnetic Field: An IMAGE Satellite Guide to the Magnetosphere educators guide, pages 23 to 28. (View Less)
