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)
This is a lesson about phase changes. Learners will observe ice melting and freezing under a variety of conditions and relate that to the Messenger mission. This is lesson 1 of 12 in Exploring Ice in the Solar System.
This is an activity about the differences in thermal behavior between similar materials having different physical properties. Learners will measure temperature of two different surfaces; sand and stone; on a sunny day, make a series of temperature... (View More) measurements, and plot the results. Extensions include experimenting with different materials, using temperature sensors and noncontact infrared thermometers. The activity is analogous with remote sensing of thermal properties in the Saturn system measured by Cassini. (Note: a separate version of this activity was developed in 2008 for PUMAS - Practical Uses of Math and Science). (View Less)
