Grade 8 Science
1:8 Project: Reactors - This assignment is not currently included on Grade 8 Science
This is a tough assignment. If you wish, you may instead write 400 words comparing some of the ways we produce electricity (coal, nuclear, hydroelectric, wind, solar, osmotic, tidal etc.). Explain 2 advantages of at least 3 of these methods over the others. Conclude by saying which one you think we should use most. You could start by reading this.

2:9 Science 8 II Project: Making Graphs
Use this fantastic NCES website to make your graphs. You can do a line graph in place of the pictograph, since they don't have a pictograph option. Be sure you give each of your graphs a title and label both the x and y axis, including units. Also, please INCLUDE YOUR FULL NAME IN THE TITLES. When you are happy with how each one looks, go to the Print/Save tab to download them, so you have a backup. It is probably best to save them as jpeg (,jpg) files unless you have the ability to make pdfs. Then you can email them to me or upload them to the project page in OW. |
3:2 Experiment: Determining Volume
|
This shouldn't be too difficult. Just remember what volume is: the amount of space something takes up. You need to determine the volume of two objects: a rectangular solid (like a shoebox or a piece of finished lumber) and an irregularly shaped object (like a rock). The volume of a rectangular solid is just length X width X depth. Measure the three dimensions and multiply them together. To measure the rocks you need to be more creative. If you drop them into a container that allows you to read the water level (pyrex measuring bowl, water bottle, even many blenders) then you can just determine the change in the water level after you drop each one in. You may have to remember that 1 milliliter = 1 cubic centimeter (or if you are in the English system 28.875 cubic inches = 1 pint) |
3:5 Experiment: Mass of Gas
Does air have mass? Everything that has mass is attracted to everything else that has mass by the mysterious force of gravity. You and your computer have a small amount of gravitational attraction for each other right now. However, we are most attracted to the earth because it is the thing near us with the most mass. That's why you and your computer aren't floating off into space right now. This experiment will help us to see if air has mass by comparing two different amounts of air to see if one has more attraction to the earth than the other. The more the mass the greater the attraction. To watch me do this experiment click here.

4:4 Project: Volcanoes
Be sure your paper is at least 600 words long and is written in your own words. Although the writing should be your own it will obviously be based on things that you have read from other sources. List those sources at the end of your paper under the heading Works Cited. Feel free to refer to your sources in your writing and even to use some exact quotes from your sources as long as you "put them in quotation marks like this" (Putnam, 2011). Otherwise you are "committing plagiarism and cannot receive credit" (Putnam, 2009). Works Cited (example for a website and a book) Putnam, Jesse. "My Amazing Article." Online posting. 4 June 2009.

6:4 Project: The Moon and Tides
This report should be a minimum of 200 words. Here is a good place to start. |
6:12 Project: Marine Report
You only have to respond to one of the two prompts. This doesn't have to be long, but it needs to be well-researched and in your own words as usual. Don't worry about getting the answer "right." It is more important that you do research and then present and support your own thesis (opinion or argument). For the fish meal question you should check on the influence of El Nino and La Nina on fishmeal prices and production. For the Jacques Cousteau article be sure you focus on two or three reasons you think that he was important to the science of oceanography. What did he do, produce, or influence that made the biggest impact?
