Chemistry of Materials – Coordinated Science II – 4th Marking Period Project
DUE TUESDAY, MAY 8, 2007
Assignment and Objective: Understanding atomic and molecular structure expands our knowledge of the nature of the material world and advances the technological sophistication of society. Each student will learn about the history and chemical make-up of a commonly used material, and present that information to the class. Students will also be responsible for learning about the topics that are presented by others.
1. Each student will be assigned a topic by lot (random drawing from a container). Each student in the class will have a different topic to research, which will be one of the following topics:
∙Amber∙Henna∙Plastic Bags∙Chili peppers∙ Erasers∙ Honey∙Polyurethane foam
∙Margarine∙Food Coloring∙Food Preservatives∙Citronella Oil∙Kava
∙Artificial Sweetners∙MSG∙Licorice∙Chicken Eggs∙Catnip∙Kitty Litter∙JELL-O®
∙Bug Sprays∙Rain Coats∙Golf Balls∙Sticky Notes∙Soap Bubbles∙Sunscreens
∙Marshmallows∙Gasoline∙Artificial Snow∙Teeth Whiteners∙New Car Smell
∙Motor Oil∙Ice Cream∙Glass∙Opal∙Shampoo∙Shower Cleaners∙Pencils and Pencil Lead
∙Fireworks∙Fluoride∙Aircraft Deicers∙Chocolate∙Silly Putty∙Self Tanners
∙Hair Coloring∙Cheese Whiz∙Asphalt∙Baseballs∙Lycra/Spandex∙Lipstick
This is an independent, at-home research project.
2. Each individual student will present their research information to the class by presenting a brief oral presentation and an 11” by 17” Shutter Fold (foldable) display of their work, which is constructed according to the attached directions and as demonstrated by the teacher. The display is to include the following:
1. a history of the use and invention of the material.
2. diagrams/drawings of the chemical structures, or chemical formula of all the ingredients that make up the material.
3. the health hazards and health benefits of the material.
4. a biography of the inventors of the materials, or a description of a company that manufactures the material.
5. a copy of a patent from http://patft1.uspto.gov/netahtml/PTO/search-bool.html or
http://www.google.com/patents where the name of the material, or the important chemical ingredient in the material, has been put in as a search term.
6. A completed information sheet about the patent.
7. pictures of the material, or actual samples of the material.
8. The student’s research information should include a bibliography (MLA format). This is a formal presentation. The writing and project should reflect a student’s best effort.
3. During the oral presentations, the audience will take notes about each of the materials; everyone will be responsible for knowing the important facts about each material and will graded on their proper participation as an audience.
4. The finished project is due on Tuesday, May 8, 2007. The Middletown Cavalier Chemical Science Meeting will commence on May 9 and run through May 11 to allow for all students to have an opportunity to present the important information about each topic. Late projects will not be accepted. Students must be prepared to present on May 9. The project is 20% of the marking period grade and will be evaluated as follows:
∙ Visual Aid/Foldable presentation 20 points
∙ Important information included 18 points
∙ Well organized 06 points
∙ Pictures of Material 06 points
∙ Copy of Patent with Completed Information Sheet 20 points
∙ Bibliography – must have two sources 12 points
∙ Audience Notes 18 points
4th Marking Period Chemistry Project - Attach This Patent Information Sheet to the patent that you hand in for your project. The project is due Tuesday, May 8, 2007
Patent Information Sheet
Student Name __________________
1. What is the name of the invention?
2. What is the Patent Number of the invention?
3. What is the name of the inventor? If the patent had been assigned to a company, what is the name of the company that “owns” the patent?
4. What is the date of the invention?
5. Summarize the claims, or specifications of the invention. Why did the inventor come up with this idea?
6. What did the inventor do to show that his invention actually works? (This is called reduction to practice.)
7. What resources did the inventor use to manufacture his product?
8. Summarize the history that led to the invention (prior art). What improvements did the inventor make, or why is the invention useful?
9. Is the invention an example of the saying “Necessity is the mother of invention?” Why, or why not?
