No Prep Plans: Year 8 Biology – Energy in Food (Calorimetry Lab)-Grades 6-8

No Prep Plans: Year 8 Biology – Energy in Food
Research + Group Project: Food Energy Calorimetry Lab

Bring food science to life with an engaging, hands-on calorimetry investigation! In this inquiry-based lesson, students explore how the energy stored in food can be measured by burning food samples to heat water, collecting experimental data, calculating energy released, graphing results, and evaluating the strengths and limitations of their investigation.

Designed as part of the No Prep Plans: Year 8 Biology series, this resource combines practical laboratory skills with scientific reasoning, data analysis, and real-world applications of nutrition and energy transfer.
