The Energy Quest
To help you with this inquiry, you will be using the Energy Quest website.
Click on this link here to take you to the site. Then, open up Firefox again in a new window and come back here to get instructions for the first part of the quest.
Part 1 - The Energy Story
(a) Open up a new Microsoft Word document and save it as "Energy Quest" in your folder. This will be your electronic UI book. We're not going to have paper UI books for this unit of inquiry.
(b) Make the title "Energy Quest" using Word Art.
(c) Make your first heading "Part One - The Energy Story"
(d) Click the computer screen on the desk on the Energy Quest homepage
(e) Read the text carefully and answer these questions in short paragraphs in your Word document.
- What is the definition of energy?
- What "work" can you see, feel or hear energy doing around you at the moment? Try to include five examples.
(g) Read the first section, and then read the "Stored and Moving Energy" section.
(h) Type the explanations of potential and kinetic energy into your Word document. Then find one library book that contains more information about potential and kinetic energy. Type any information you find that helps you to understand what they are.
(i) Read the pencil example very carefully and do what it says so that you really understand it. Read it again and do it again if you need to. Then, on a piece of white A4 paper, draw a clear diagram to explain what it means. We will then scan your drawing and you can insert it into your Word document.
