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) climate change, and learn about the tools used to explore ice layers on Earth and in the solar system. Connections between rings of a tree and rings in an ice core will be made. Activities include small group miming, speaking, drawing, and/or writing. This is lesson 7 of 12 in the unit, Exploring Ice in the Solar System. (View Less)
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) collaboratively in a team. Activities include small group miming, speaking, drawing, and/or writing. This is lesson 3 of 12 in the unit, Exploring Ice in the Solar System. (View Less)
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) ice flowing differently under stress, and will investigate landscape changes as a result of large scale glacial movement. Activities include small group miming, speaking, drawing, and/or writing. This is lesson 5 of 12 in the unit, Exploring Ice in the Solar System. (View Less)
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 clouds. Activities include demonstrations by the teacher,... (View More) small group miming, speaking, drawing, and/or writing. In addition to commonly found classroom materials, dry ice, an aquarium or terrarium container, magnifying glass are needed. This is lesson 6 of 12 in the unit, Exploring Ice in the Solar System.

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) light sources and attempt to measure the strength of polarization. This activity is from the Touch the Sun educator guide. (View Less)
Materials Cost: Over $20 per group of students
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) bandpass of the filter. This activity requires various light sources, a diffraction grating, and two or more color filters that are transparent to some wavelengths of light and opaque, or nearly opaque, at other wavelengths. This is an activity in the Touch the Sun educator guide. (View Less)
Materials Cost: Over $20 per group of students
Students identify the actual colors of objects bathed in monochromatic light and learn how three colors of light can be combined to produce colors ranging from black to white. Students see how space observatories make use of monochromatic filters to... (View More) collect data on the color of objects in space. The activity is in unit four of the "Space-Based Astronomy" guide that contains background information, worksheets, assessment activities, extensions, and alignment to national education standards.

Students determine the ability of various lenses and mirrors to gather light in order to compare and calculate their light gathering power. This activity is part of Unit 3 in the Space Based Astronomy guide that contains background information,... (View More) worksheets, assessments, extensions, and standards. (View Less)
