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

Mixing Water

Lab Summary

Use a temperature sensor to understand that mixing hot and cold water results in a new temperature that is between hot and cold.


To understand this content, students:

  • Identify the temperature of different objects.
  • Recognize that the position of the line on a graph relates to the hot or cold temperature of the object.
  • Predict the resulting temperature of mixing hot and cold water.

Sensors / Equipment Used:

PASPORT Temperature/Sound Level/Light Sensor


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

Materials Used:

Large paper or plastic cup 
Ice water, approximately 5 °C - 200 mL
Warm water, approximately 40 °C - 200 mL
Towels - Several

The Associated Bundle:

Elementary School Science Standard Sensor Bundle


This bundle contains the probeware needed to perform all 25 lab activities in the Elementary School Introductory Science Experiments.

Interface Required

This experiment may require software and an interface for data collection.
