2. Liquid Crystal Temperature Sensors

Ask students if they have seen objects that change color with temperature. (mood rings, strip thermometers..)

Discuss the RULES for using the temperature sensors:

The sensor must not be placed in the sun or near a heat source 

Always hold the strips using the clear laminated part 

Do NOT touch the liquid crystal unless instructed to do so.

Hand out liquid crystal temperature sensors to each pair of students.
