In this FACTivity, you will explore a range of instruments used by scientists. You will then use your imagination to create instruments that measure a range of classroom variables.

The questions you will answer in this FACTivity are:

1. What are at least five more instruments with the word “meter” in their name, and what variables do they measure?
   2. What instrument names can be created for imaginary use in the classroom and what unit of measurement would these instruments use?
   3. What are the characteristics of a useful unit of measurement?
   4. How does having a measurement range help someone to understand the measurement?

Materials:

• Access to a library or the internet for research
• Graphic organizers (included)

An extension activity is also included.
