Understanding Power using Kirchhoff’s Rules

An outstanding lesson awaits your physics fledglings! After reading about how hydrogen can act as an energy carrier, they examine the electrolysis of water using solar power. They test the gases produced for flammability and will...

Assist your class with correctly calculating the values for force, work, and power as they determine the amount various activities require. They gather data and participate in a group discussion to compare results upon conclusion of the...

After reading about how wind turbines work to collect clean energy, groups brainstorm and design their own windmill. Within the provided financial and physical constraints, groups must build a working windmill using only the materials...

The left hand rule, also known as Fleming's rule, is covered here with explanations and pictures to help undertanding. Examples of electric motors and generator use are given. A helpful set of slides which will help early physics...

He did the same amount of work, but somehow the result is more powerful! Show learners the difference between work and power and how the calculations relate to moving a box. 

Aristotle said, "The more you know, the more you know you don't know." Physics includes everything from the laws of motion to quantum gravity. An interesting video attempts to cover the main concepts of every branch of physics in only a...

Explore the basics of electric current with an introductory video lesson. The 28th installment in the Crash Course physics series discusses characteristics of electric current. An explanation of Ohm's Law helps scholars understand the...

Scientists know wind is a renewable resource, but is it an efficient one? Scholars adjust the propeller diameter on a wind turbine, the wind speed, and the conversion efficiency within range to learn about the efficiency of these...

What a wonderful way to explore wind power! Through this instructional activity, learners get a background in the history of wind power, create their own wind turbine, and the test their designs. This is a terrific way to tie scientific...

What makes a clock tick or a bulb light up? The concept of work is explained to a backdrop of clever animation. Physics fans learn that the amount of work equals the product of the force and distance, and that the rate equals the amount...
