Kinetic and Potential Energy
Investigation 3 – PreLab
Wind energy engineers design, build, and monitor wind turbines that convert the kinetic energy of the wind into electrical power.
This Investigation is designed to help you to answer the following Focus Questions:
- Can one form of energy be converted to another? Support your answer with data from the experiments.
- How does converting energy from one form to another relate to the Law of Conservation of Energy?
Note: These questions are located in your SDR at the beginning and end of the Investigation.
As a class, read the Background(s) in Investigation 1. When finished, discuss the following concept as a class:
- Chemical potential energy can be released when substances react chemically to form new substances.
LEARN THE LabLearner LINGO
The following Key Term is introduced in the Investigation Background(s). It should be used, as appropriate, by teachers and students during everyday classroom discourse.
- chemical potential energy
Note: The definition of this term can also be found on the Introduction page to the CELL.
Note: Additional words may be bolded within the Background(s). These words are not Key Terms and are strictly emphasized for exposure at this time.
SET FOR SUCCESS
- Complete the Recall section in your SDR.
- Is there energy in chemical reactions?
- Can energy from chemical reactions be transferred to other forms of energy?
- You will explore how changes in the amount of vinegar affect the chemical potential energy present in the reaction of baking soda and vinegar.
- Play the video below. Remember to follow along with your SDR and make any notes that you think might be helpful in the lab.
- After the video, divide into lab groups to discuss strategy for the lab. For example, you may assign certain group members to perform specific functions during the lab.
Note: The purpose of the video is to allow you to anticipate the laboratory experience you will soon encounter. You should leave this PreLab session with a firm idea of what to expect and how to perform in the lab.
Note: Homework is posted below the video.
You should review the Investigation and video in preparation for the Lab.
