Simple but effective heat activity! Use this engaging 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 worksheet has a quick reading about how thermostats work (thermal expansion) and then gives student instructions on how to use the bimetallic strip. Students will use a candle as a heat source. Students then draw a before and after and explain how the activity demonstrates thermal expansion. This is a quick (but very effective!) activity, so we often use this as a station with this Easy Hands-On Thermal Expansion Activity with Balloons and our Clicking Coins Activity.
