• Physical properties, chemical and physical changes
• Health and Safety Regulations
• Converting metric into imperialmeasurements
• Scaling up recipes
• Cost analysis (i.e. Food items are not taxed)

Teaching Planning Notes

• Review assignment including prior learning required and assessment and
  evaluation tools
• Review Health and Safety Regulations
• Instruct students to bring in winter gloves or a towel.
• Obtain freezer bags. They work the best because they are thicker and less likely to break than sandwich bags. If you are using regular plastic bags make sure you double bag the small bag. (Zip lock work the best)
• Give laboratory instructions only to student A (the trainer)
• Safety Precautions: Teachers must identify students with any milk allergies. These students cannot eat the ice cream or get it near their faces. In the case of severe allergies, students can work on the Analysis portion of the assignment.

Note 1: The application questions are geared towards the TFH 3E course
Note 2: A community connection for this activity could include students serving their homemade ice cream to another class, staff, local day care or retirement home.
Note 3: Students could obtain prices of the materials in a variety of ways such as: taking a field trip to a grocery store, reading weekly grocery flyers, or going to an on-line grocery shopping site
