In this lesson, students will be introduced to how the Doppler effect changes our perception of wavelengths of sound (pitch) and light (color). Students will model how astronomers use the line spectra of stars to identify elements in the stars and... (View More)

Audience: Middle school
Materials Cost: Over $20 per group of students

This is an activity about the states of matter. Learners will participate in a demonstration to reintroduce them to three states of matter: solid, liquid, and gas. The demonstration also introduces them to a fourth state of matter, plasma, through... (View More)

This is a lesson about the formation of glaciers, ice layering and stratigraphy, and the cryosphere and cryobotics. Learners will collect evidence of layering, explore the science story that layering tells, study snow and ice for insights into... (View More)

This is a lesson about condensation, snow and snowflakes. Learners will investigate how water and ice exist in the atmosphere as they study water vapor condensing, find that clouds are made of tiny droplets of water, and notice that snow forms in... (View More)

This is a lesson about how and why ice flows, especially in a large mass such as a glacier. Learners will experience the qualities of viscoelastic materials and view videos of glacial ice flows. They will observe ice flows and materials other than... (View More)

This is a lesson about the characteristics of ice as a mineral and how it compares to other minerals with respect to hardness. Learners will observe ice crystals, develop a hardness scale and position ice on it. Learners will also practice working... (View More)

In this activity, students will demonstrate the generator effect, which is due to electromagnetic induction when a conductor (a long metal wire) moves through a magnetic field. Materials required to this activity include: a 100-foot extension cord... (View More)

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)
