of this demonstration in action.
Use a conductometer (available from science supply catalogs and Amazon) to demonstrate conduction of heat. Students record the materials of the prongs and make predictions as to which material will conduct heat the fastest. They then record the actual results as they watch you perform the experiment or do it themselves. This is a HALF PAGE worksheet so you make half the copies and cut in half. It's quick, so I use it as a station with other quick conduction and convection activities.
This is a Word file, so it is easily editable for your needs.
Combine this resource with some of the following to make a day of stations:
Convection in a Lava Lamp
Convection in a Liquid Activity
Hands-On Convection in Gases Activity
Convection in Hot Air Balloons Reading
Density and Convection Reading
Teaching heat? I highly recommend this Middle School Heat Transfer Lab
and this Insulator Design and Build Challenge
