Reflection: Developing a Conceptual Understanding Measuring Changes - Section 3: Students in Action


Concepts are abstractions that can be applied to new situations.

In this lesson students learn the cause and effect relationship between the volume of fluid and the temperature of the fluid.

A pattern is clear to see in the graph and we know that thermometers are reliable as a measurement tool.

This understanding can be applied to other types of thermometers. 

Digital thermometers measure change in electrical resistance.

Ear thermometers measure thermal radiation coming from your body.

Liquid crystal thermometers reflect different colors of light at different temperatures.

It is important to delve into conceptual understanding to create the background knowledge they will need to transfer understanding to new situations.
