Simple but effective!Use this quick activity to teach about thermal expansion and particle motion using a bimetallic strip.
Do you have a bimetallic strip in your classroom? If not - try one, they're really cool and only 10 bucks on Amazon! This is a HALF PAGE (make half the copies and cut in half) worksheet that has a quick reading about how thermostats work and then gives instructions on how to use the bimetallic strip. Students draw a before and after and explain how the activity demonstrates thermal expansion. This is a quick activity, so we often use this as a station with this Easy Hands-On Thermal Expansion Activity
and our Clicking Coins Activity
. This is a Word document, so it is easily editable.
