The pages of this resource are in landscape view and ready-made to use as slides in a presentation on energy transfer in your high school physical science course. Begin with pertinent vocabulary and finish with an explanation of the...

How much work is done when a force moves a block? How far will power lift a block? And how much work can be done by a motor? These are the kinds of questions you will find on this physics problem solving sheet. With 19 problems to solve,...

Written out on this page are 22 problems for physics aces to solve. There isn't enough room for them to solve on the same page, so they will need to be set up and computed on a separate sheet of paper. Pupils answer questions such as,...

Identify how solar energy generates thermal energy by constructing solar cookers with your students. They will evaluate the factors that affect efficiency and the lesson can be adapted to capture data in a variety of ways.

Students examine the basics of luminous efficacy and why it is used.  In this light source instructional activity students test energy efficiency and the luminous efficiency for babies.

Students consider the impacts of global warming and brainstorm ways to help decrease their contribution to the problem.  In this climate change lesson plan, students are exposed to facts concerning global warming and think of ways...

Students reflect on their personal time management and take a quiz identifying areas of improvement.  In this time management lesson, students explore a variety of Internet links and articles that offer strategies for improving time...

Students explore the concept of efficiency. In this efficiency lesson, students read an article about efficiency in various industries such as health care, retail, and auto repair. Students identify a company that they think could...

The "Who's Guide to Saving Our Planet" helps students protect the environment through superior energy efficiency.

By the end of this section, you will be able to contrast consumer surplus, producer surplus, and social surplus; explain why price floors and price ceilings can be inefficient; and analyze demand and supply as a social adjustment mechanism.

Practice what you've learned about consumer and producer surplus in this four-question exercise.

Practice what you have learned about productive efficiency and allocative efficiency in perfect competition in the short run and the long run.
