Middle School Physical Science Teacher Guide

(PS-3852)

Features 23 core lab activities that cover the fundamental concepts of Force & Motion, Energy Transfer, Electricity & Circuits, Fluids and more.

Investigating Evaporative Cooling

Lab Summary

Use a fast response temperature sensor to measure the change in water temperature as it cools.

Theory

In this activity, students investigate the transfer of heat and the cooling rate of warm water.
Students investigate and observe changes in water temperature while learning:

  • That energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, and the nature of a chemical
  • That heat moves in predictable ways, flowing from warmer objects to cooler objects, until both reach the same temperature

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the change in water temperature as it cools
  • Designing and making two different-shaped foil containers for water
  • Testing the cooling rate for water in each of the containers
  • Testing the cooling rate for water in still air and water that is fanned
  • Using math skills to find the difference between changes in time and changes in temperature
