(PS-2875D)

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

Temperature and Change

Lab Summary

Use a temperature sensor to determine the effect of temperature on the time it takes for a sugar cube to dissolve or an antacid tablet to react with vinegar.

Method

To understand this content, students:

  • Time how long it takes a sugar cube to dissolve in three different temperatures of water.
  • Time how long it takes an antacid to react with three different temperatures of vinegar.
  • Analyze the data to determine the effect of temperature on the time it takes for a change to occur.

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.
