HotLinks

What is a HotLink?

Occasionally you will find instructions in the Addison Wesley Science 10 textbook that direct you to the Internet for a particular resource. We've developed this HotLink page so that you will always be able to reach safe, reliable resources on the World Wide Web.

These HotLink pages also provide plenty of extra Internet links as additional resources.

The following HotLinks are divided into the three major concepts you will find in the Energy Flow in Technological Systems unit. Click below to jump to a particular topic, or simply scroll down this page.

  • 1.0: Investigating the energy flow in technological systems requries an understanding of motion, work, and energy
  • 2.0: Energy in mechanical systems can be described both numerically and graphically
  • 3.0: Priniciples of energy conservation and thermodynamics can be used to describe the efficiency of energy transformations

Some of the recommended HotLinks may require that you have a plug-in installed in your Internet browser. This allows you to take full advantage of the HotLink. The following icons indicate which plug-ins are necessary. Links to all of the most recent versions of browsers, plug-ins, and helper applications can be found at the Science 10 help page.
