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 magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. This is the fifth activity in the Exploring the Earth's Magnetic... (View More)

This is a series of three activities about light and spectra. First, learners will construct their own spectroscope, observe common light sources, record the observed spectra, and compare their findings. Next, learners will use their spectroscopes... (View More)

This is an activity about photosynthesis. Learners will use the basic principle of photosynthesis and investigate how light intensity diminishes as a function of distance from the light source. Questions help them connect these two ideas to... (View More)

Using a constructed Mystery Light Box, learners will observe what is in the box without removing the object from the box, shining a light into the box, or reaching hands into the box, and they will draw what they see. Next, they will brainstorm... (View More)
