Two Weeks

Materials Needed

computers with internet access


Small glass jars or cups 3-4/group

2-3 bowls to test materials/ group

fabric and materials to test


Pre/Post test


1. Use the internet to research equipment used by the Iditarod Mushers.

2. Conduct simple experiments on different materials to determine if it is a good conductor or insulator.

3. Write a compare/contrast essay to explain why one material would make better dog booties than another.

4. Use Microsoft Excel to show the results of experiments using graphs or charts.

5. Use internet to communicate with Iditarod mushers and experts via e-mail


Day 1-Administer pre/post test Introduce students to Iditarod sites to be used in this unit. Start exploring the history of the Iditarod race.

Day 2-Have the students research the equipment used during the Iditarod race Make a list of items used during the race.

Day 3-Students go to the BSSD musher resource page(address) and choose a musher that they can e-mail and use as an expert resource for Iditarod questions.

Day 4-The students will use the internet to shop for these products at and Find out what they are made of and record the price of each item.

Day 5-Students put their equipment list and prices into Microsoft Excel and calculate the total cost of their equipment using the Excel spreadsheet.

Day 6-Teach the experimental process, establish a question to be answered and formulate a hypothesis for the experiment that you will conduct. (ie What material is the best insulator? hypothesis-cotton)

Day 7-Conduct a simple experiment to determine whether the material some of the products are made of is a good conductor or insulator. Experiment: Place a small cup or jar in the center of a larger bowl. Surround the cup or jar with the material being tested. Place a thermometer in the cup or jar and record the temperature reading. Pour ice around the outside of the material being tested so the material becomes a barrier between the ice and the inside container. Let this stand for two minutes then take another temperature reading. Repeat this procedure for all of the materials being tested. Record all results

Day 8-The students will create a powerpoint presentation to display their results. They must have a minimum of five slides to include: a title slide, a list of Iditarod equipment and what each is made of, a chart or graph to display experimental results, a pros and cons page to compare the materials that the equipment is made of, and a page to cite their sources and conclude their presentation.

Day 9-Write a compare/contrast essay to determine what kind of material would be the best choice to make dog booties. Base your reasons on your experimental results.

Day 10-Administer pre/post test.

Evaluation/ Rubric

Under Construction

Teacher Notes

Depending on the age of your student and their ability levels with computers, these daily tasks may require more than one day to complete.




Students could write a persuasive essay to convince other students to buy a particular brand or kind of coat, boots, etc.
