Biology through Inquiry Teacher Guide

(PS-2870C)

Features 25 inquiry based labs covering the fundamental concepts of cell biology, ecology and physiology.

Energy Content of Food

Lab Summary

Use a temperature sensor to measure the change in temperature of water that is heated by burning samples of food and to compare the energy content of those samples.

Theory

Guide students to measure the change in temperature of water that is heated by burning samples of food and to compare the energy content of those samples.
