Summary and Objective
Students will understand that ice was a necessary resouce during the 1800's and into the 1900's. Students will learn how ice was harvested and then preserved for use during the warmer months of the year.
Teaching Plan
Step 1.
Ask students to describe the ways that they and their families use ice. List ideas on chart paper.
Ask students how they think ice was used during the 1800's.
List all ideas on chart paper.
Next, ask students where the ice that they use comes from. List ideas on chart paper.
Ask students where the ice that was used during the 1800's came from. You may want to remind them that this was prior to electricity.
List all ideas on chart paper.
Step 2.
Show photographs of “Harvesting ice in New England” in the americancenturies digital collection. Read and discuss each label paragraph with students.
Step 3.
Look back over the charts that were previously made listing ideas for the use of ice and where ice came from. Add any new ideas. Using a Venn diagram to chart the differences and similarities between the use of ice now and during the 1800’s. Do this also for where ice comes from. Note and discuss similarities and differences
Step 4.
Additional Activities Follow:
Step 5.
Print copies of the ice harvesting photographs. With the students, generate a sentence to describe each photograph.
Step 6.
During another lesson present the ice harvesting photographs with the captions. Working in small groups, students sequence the captioned pictures. Each group presents their sequence to the class; differences are discussed.
Step 7.
The links included in this lesson give more information on ice harvesting and preserving ice. Discuss how ice was kept cold in ice houses using sawdust.
Pose the following question:” If you had to keep an ice cube warm for 48 hours at room temperature how would you do it”? “What materials would you need”? Generate a list of modern day insulating materials. Gather those materials that are safe to handle, include sawdust or shavings if available.
Working in small groups have students design,test and record the results of their “modern day” ice boxes using collected materials and thermometers. Students share results and each team of students then try to better the insulating factors of the previously made ice boxes.
