IaPS Energy: Activity 58 “Follow the Energy” Absent Work Key Words: Chemical Energy, Elastic Energy, Electrical Energy, Light, Nuclear Energy, Sound Getting Started: 1. Look for a relationship among the words in each list. Cross out the word or phrase that does not belong. Circle the word or phrase that includes the others on the list. Describe how the circled word or phrase includes the others. List 1 roller coaster gravitational potential energy List 2 absorb release transformation chemical energy kinetic energy energy interaction height List 3 potential energy the Law of Conservation of Energy energy transfer energy transformation efficiency 2. Read the Introduction and Challenge to Activity 58, “Follow the Energy,” in your Student Book on page D-32. Procedure: 1. Look at the table “A Summary of Energy Types” on page D-34 of your Student Book. The table describes different types of energy found in nature or human inventions. 2. Examine the eight Energy Event Cards that are attached to this packet, and compare them to the table. 3. Choose an Energy Event Card, and identify all the energy types involved in the transformation shown. Use Student Sheet 58.1, “Follow the Energy,” to record the energy types before and after the transformation. 4. In the last column on Student Sheet 58.1, “Follow the Energy,” write a complete sentence or two that describes the energy transformation shown on the Energy Event Card. Include all the energy types you listed. 5. Repeat Steps 3-4 for the other seven Energy Event Cards. Analysis Questions: 1. Look at the lists of words shown below. List 1 kinetic energy potential energy light sound List 2 chemical energy potential energy nuclear energy thermal energy List 3 fossil fuels stored energy chemical energy absorb energy release a. Look for a relationship among the words in each list. Cross out the word in each list that does not belong with the others. b. Circle the word in each list that is a category that includes the others. c. Explain how the word you circled relates to the other words in the list, and how the word you crossed out does not fit in the list. ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ 2. Look at the diagram on page D-35 of your Student Book. It shows the transfer of energy from the Sun all the way to a student using a computer. Using the table on page D-34, decide on the type of energy at each of the situations. There may be more than one energy type at each place. ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________ Follow-Up: 1.
