What's the tallest tower you can build using only two sheets of newspaper?
Here's the challenge: getting the newspaper to stand up, without using tape, staples, glue, or other materials. But you can bend, fold, or tear the paper itself.
What You Need
• 2 sheets of newspaper
• ruler
Make a Prediction
Make a prediction about how tall a tower you can build. What is your prediction based on?
Try It Out
1. Now construct your tower. If you think you can make it taller, keep redesigning it until you can't go any higher.
2. When you are finished building, measure the height of your tower.
Explain It
• How did your result compare to your prediction?
Give possible reasons for any difference. What limited the height of your tower?
• If you could use one other material to make your tower taller, what would it be? Why?
Build on It
• How much taller can you make the tower if you can add 20 centimeters (about 8 in.) of tape? (You can't tape the tower to the table.) How tall can you make the tower and have it support the weight of a pack of chewing gum?
• How well does your tower withstand environmental forces? Use a fan to imitate wind gusts or shake the table gently to imitate an earthquake. How can you change your design, using 2 sheets of newspaper and 20 cm of tape, to better withstand these forces?
Each student will give a recorded presentation to the class on their selected water pollutant. The presentation should be between 60 and 90 seconds and should include easy to read visual aids. This presentation will be recorded and posted on this website for all students view. There will be a CP on the pollutants presented; every student is responsible to know about ALL pollutants, including presentations from the other class (a.m. responsible for p.m. and vice-versa). A failure to pass this CP will result in revoking the opportunity to travel to Coon Creek in Armada for on-site water quality testing.
The presentation should include a thorough definition of the pollutant, the source of the pollutant, the negative effect of the pollutant, how to test for the pollutant including demonstrating any Hach equipment we have available, and possible methods to remove the pollutant.

Worldwide Pollution Paper
Objective This paper is based upon worldwide problems that negatively effect population’s access to clean water.
Requirements There is never a minimum or maximum number of words or pages required to get your thoughts across in a paper similar to the one you will be writing. If that being said, I would imagine the length of this paper would be between 2 and 3 pages. To make my job easier, I’d prefer 12 points Times New Roman font with either 0.5” or 1.0” margins and 1.5 line spacing. I also cannot imagine the paper being written with fewer than 5 valid sources. I expect the paper to be free of all grammatical errors.
Paper Goals The goal of the paper is to become an expert on your topic. You should be able to provide extensive background on the events of your topic. You should be able to provide extensive information on why your topic is relevant and important, either on a local, state, national, or global level. If at all possible, you should be able to provide information how the event has been resolved. It would not surprise me if there was a picture or two embedded into the paper.
