In this lesson you will investigate the energy changes that occur during the chemical reactions involved in photosynthesis, cellular respiration, and combustion. You will learn how these reactions are part of the carbon cycle.

 

As you work through the lesson, you will be planning an ecotour. As an ecotour operator, you are responsible for your clients and for their impact on the environment in which your tour operates. Planning your ecotour will require you to consider how energy changes relate to situations outside of a chemistry laboratory.

 

You will need to keep your clients well-fed by offering them appropriate foods. While there are many qualities to consider when selecting food, in this case you will focus on the energy content of food. To get an idea of how much food your clients will need, you will do an inventory of and evaluate your own personal energy intake and needs.

 

Energy is involved in every activity. In this lesson you will investigate the quantity of energy you intake to support your daily activities.

 

Consider the following questions as you complete Lesson 1:

  • How does society use the energy of chemical changes?
  • How do you use the energy of chemical changes in your life?
Assignment Module 1: Lesson 1 Assignment

 

In the Lesson 1 Assignment you will prepare a spreadsheet to calculate your personal energy intake. Download a copy of the teacher-marked Module 1: Lesson 1 Assignment to your computer at this time. You will receive further instructions on how to complete this assignment later in the lesson.

 

The other questions in this lesson are not marked by the teacher; however, you should still answer these questions. The Self-Check, Try This, and other types of questions are placed in this lesson to help you review important information and build key concepts that may be applied in future lessons. You should record the answers to all the questions in the lesson and place those answers in your course folder.

 

After a discussion with your teacher, you must decide what to do with the questions that are not part of your assignment. For example, you may decide to submit the responses to Try This and other questions that are not marked to your teacher for informal assessment and feedback. Your answers are very important to your teacher. They provide your teacher with information about your learning, and they help your teacher identify where adjustments to your instruction may be necessary.
