Product Details

Heat transfer by convection occurs continuously, but is usually only felt, seldom “seen.” Two innovative demonstrations in this kit allow you to create visible convection currents in both water and air. Dramatically show the effect of convection currents in air with a lighted candle—now it’s burning, now it’s not! Follow this up by observing convection currents created when a hot colored liquid rises and a cool clear liquid sinks. Use the comprehensive Teacher Notes to relate these phenomena to applications of real-world convection patterns, such as weather and ocean currents.

Concepts: Convection, heat transfer, thermal equilibrium.
Time Required: 30 minutes
Materials Provided: Red food coloring, glass tubing, two-hole rubber stopper, aluminum foil, candle, clay, template for T-dividers, plastic tube, weighing dish.
