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.

Varying Reaction Rates

Lab Summary

Use a fast response temperature sensor to measure the change in temperature over time during four trials of Alka-Seltzer® tablets as they react and produce bubbles in a container of water.

Theory

In this activity, students investigate temperature―a factor that affects reaction rates. They also:

  • Observe and compare the varying amounts of time it takes for the reaction to run its course
    under different conditions
  • Measure the amount of time needed for a reaction to occur
  • Observe that substances react chemically in characteristic ways with other substances to form new substances (compounds) with different properties

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the temperature of two different systems
  • Measure the change in temperature over time during four trials of Alka-Seltzer® tablets as they react and produce bubbles in a container of water
  • Using math skills to average temperature results

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.
