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.

Conservation of Matter

Lab Summary

Use a temperature sensor and absolute pressure sensor to measure the change in temperature and pressure of an oxidation reaction.

Theory

Students investigate a chemical change and confirm the Law of Conservation of Matter. Using the temperature and pressure sensors, students measure changes during a synthesis reaction.

Students investigate and observe the conservation of matter during a chemical change while they:

  • Achieve a familiarity with chemical and physical reactions and with the ways substances can behave or change in the process
  • Measure a reaction that results in heat transfer
  • Gain skills and confidence in using scientific measurement tools, the temperature and pressure sensors, as well as the graphing capability of a computer to represent and analyze data

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the change in temperature and pressure of an oxidation reaction
  • Measuring the mass of a closed system before and after an oxidation reaction
  • Measuring the change in temperature and pressure during the oxidation reaction of steelwool that has been soaked in vinegar

Sensors / Equipment Used:

PASPORT Chemistry Sensor

(PS-2170)

Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
