Elementary School Science Teacher Guide

(PS-2875D)

Features 29 inquiry based labs designed for elementary students and coordinated with the standards for life, earth and physical sciences.

Chemical Reactions

Lab Summary

Use a temperature sensor to measure the change in temperature as two substances chemically react.

Method

To understand this content, students:

  • Observe the properties of matter before and after mixing different materials.
  • Identify clues that can be used to determine whether or not a new substance has formed.
  • Use a temperature sensor to measure the change in temperature as two substances chemically react.

Sensors / Equipment Used:

PASPORT Temperature/Sound Level/Light Sensor

(PS-2140)

Allows students to conduct all three measurements simultaneously and continuously. For use with PASPORT Interfaces.
