It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the changes occur and calculate information to use that relates to daily food consumption and the energy used in the body.

Instructional Ideas

• Have students use the lab values they obtain and compare with those found on food labels in supermarkets
• Instruct the class to research organic foods versus processed foods, comparing the information found on their labels with values obtained from the experiment

Classroom Considerations

• Provide math assistance to learners who require additional support
• ELL learners require additional help with the assessment portion of this experiment
• This is the second lesson in a series of six related resources

Pros

• Hands-on application encourages participation and fosters excitement, thus allowing acquisition of the concepts
• Lesson relates to changes occurring in the body and conclusions may be drawn after initial-data collection

Cons

• None
