Engagement and Exploration (Student Inquiry Activity)
What are the characteristics of the various types of fabric? Students may mention some of the following characteristics:
Allow teams to examine the fabrics to determine how they differ. Encourage students to experiment with many different characteristics of the fabrics. For example, students might examine absorbency by placing pieces of the fabrics into water to see if how much water they absorb. These investigations should be relatively informal and last for only a short time.
Elaboration (Polar Applications)
Assign students to research teams. You may wish to appoint Principal Investigators for each group.
Explain to students the team structure of many types of research teams. These teams usually consist of a Principal Investigator (PI) who is responsible for overseeing the entire research project. PIs assign research responsibilities, develop safety and logistical procedures, and oversee the project budget. It might be useful to pick self-motivated and industrious students to act as Principal Investigators.
In addition to the PI, research teams should also have:
Make sure that students understand that, although each team member will have a specific specialty, all team members are responsible for the final product.
Ask students to read about Peter Amati's research in the Weddell Sea on The Teachers Experiencing Antarctica and the Arctic web site: ../../tea_amatifrontpage.html
In parcticular, note the journal entry from June 6, 1992, in which Peter describes the extreme cold and dryness of Antarctica. ../../amati/6.5.1992.html
Another interesting reference can be found on the GLACIER web site at ../../expedition/2_trainingcamp.html Students should use the information they find to inform their long underwear design.
Student teams research temperatures and conditions found in the Weddell Sea. Weddell Sea conditions can be found on the GLACIER web site at ../../weather/weather.html
Direct teams to discuss what they will need to know to develop their long underwear. Remind students to take into account the characteristics they feel would make the best long underwear. Students should develop a plan by which they can develop their long underwear recommendation. Teams will need to determine the types of tests they will do, what materials the will need, and what they think characterizes the best long underwear.
If necessary, student teams can continue to develop their plans as homework.
Exchange (Students Draw Conclusions)
As a class, determine which tests you will perform and what requirements you feel will make the best long underwear.
Post a list of the selected tests and characteristics.
