Compact Fluorescent Lamp Experiments

Need a bright idea for an engaging lab? Watch your class light up as they explore the difference in efficiency between incandescent and LED bulbs! The resource makes use of simple materials and encourages learners to infer what's...

Oh nuts! Do macadamias or almonds produce more thermal energy? Energy enthusiasts find out with this experiment. The objective is to demonstrate to your class how the chemical energy contained in foods can be converted into useable...

Here is a fascinating find for future techies: a video about how various light bulbs work. Because it begins with the incandescent bulb, it covers a bit of history of the light bulbs. It concisely and creatively describes how halogen...

Rev up your teaching with a lesson on engines! The 24th installment in a Crash Course physics series explains the basics of an engine through a discussion of thermodynamics. The instructor shows examples explains the efficiency of the...

This analysis activity allows students to calculate electrical usage in home lighting, and create a cost-benefit analysis for cost and energy savings by replacement of incandescent light bulbs with compact fluorescent or LED light bulbs.

Catch up on the technology that has gone into making all types of modern light bulbs. [2:57]

You've probably heard that compact fluorescent light bulbs are more efficient than incandescent bulbs. More of the electricity they use goes into producing light, and less into producing heat than with incandescent bulbs. How much more...

Compared to incandescent lamps, fluorescent lamps last longer, require less energy and produce less heat, advantages resulting from the different way in which they generate light.

Students study the history of the light bulb and how an incandescent light bulb works.  In this electricity lesson students complete several experiments on the light bulb.

If you chew or make a "raspberry" while viewing an LED light source, the light will appear to wiggle or flicker. It is not because of the light itself, but because of the vibration of your skull! Have your physics class give this a try...
