energy

This is such an intense topic to try and create a brief introduction to students. What to keep in? What can I leave out? I found the professional development (PD) resources I listed after the lesson summary to be helpful in guiding the decisions I made. These are the main ideas I’ve come up with for the moment that I would like students to take away from the activities. We will go more in depth with thermal energy in the next lessons since it is such a driving mechanism for many of the “cycles” we will be learning throughout the year.

Student Objectives:

Students will obtain, evaluate, and communicate information as well as develop and use models:

  • To describe the various forms of energy
  • To explain how one form of energy can be transformed into another
  • To distinguish between kinetic and potential energy
  • Energy is something used to make something move, make it move differently, or to change its position.
  • Energy is also something used to change matter in some way.

Key Ideas from the Lessons: 

(Source: http://assessment.aaas.org/topics)

  1. Energy can neither be created nor destroyed but it can be transferred and/or transformed. Regardless of what happens within a system, the total amount of energy in the system remains the same unless energy is added to or released from the system, even though the forms of energy present may change. If the total amount of energy in a system seems to decrease or increase, energy must have gone somewhere or come from somewhere outside the system.
  2. Within a system, one form of energy can be transformed into one or more other forms of energy.
  3. A decrease in one form of energy within a system is associated with an increase in one or more other forms of energy (unless energy is transferred into or out of the system). Similarly, an increase in one form of energy within a system is associated with a decrease in one or more other forms of energy (unless energy is transferred into or out of the system).
  4. Any form of energy can be transformed to other forms of energy and any form of energy can result from a transformation.
  5. Energy transformations can occur when energy is transferred from one system to another.
  6. Most of what goes on in the universe—from exploding stars and biological growth to the operation of machines and the motion of people—involves some form of energy being transformed into one or more other forms of energy.
Sequence of Lessons Summary:

Lesson 1:   Begin by telling students that our world is basically two things:  matter (stuff) and energy (something that makes stuff do stuff). Explain that they will be using various sources to discover some key concepts about energy. Google classroom would be very helpful here with posting the resources and supporting students on their “webquest”. If you don’t have access to Google Classroom, I suggest Edmodo as another helpful place to post these resources. Pass out the students’ sheets and go over the directions:What is energy webquest As students work on the assignment, you are circulating and offering guidance or clarification as needed as well as informally assessing students’ ideas about energy.
