1)Your topic string -
a. Your broadest topic - natural resources
How many more years would it take for the world to used up all the natural resources?
b. Your next broad topic - Raw materials
Raw materials takes million of years to form.
c. Your starting topic - renewable energy
Renewable energy provides a another alternatives for the world to use as a energy source.
d. Your narrower topic - Hydroelectricity
Hydroelectricity is electricity generated by water flow.
e. Your even narrower topic - Water flow energy
Water flow energy is the used of natural resource.
2) Think of two questions that you could ask about your topic
a. How much energy are generated using water flow?
b. What is the amount of watts are transferred from electricity power plant to a normal size town such as San Francisco?

Let's think about this string.
ReplyDeleteYour broadest topic is natural resources.
Raw materials is your next topic. Is this smaller than natural resources? What are natural resources if not raw materials? Unless you can actually think of it as being bigger because raw materials could incorporate both natural and man-made resources.
Renewable energy is definitely smaller because not all natural resources/raw materials are renewabls (e.g., oil vs solar)
Hydroelectricity is one form of energy that could be considered renewable, so that is smaller than renewable energy.
Is water flow energy smaller than hydroelectricity or is it simply another term for the same thing? This would make it neither smaller nor larger, but the same size.
Your questions are fine and you will be able to use them for the next few lessons. Just keep thinking about sizing your topic. This is probably one of the hardest assignments I give. It's hard to do this, but it should help you to think about topic size and how to go about the process.
