Miss Haniak, Science 9 Element Project
Chemistry Unit: Element Project
Purpose
The purpose of this project is to allow you to learn about one element on the Periodic Table. You will research your element and then briefly present the information to the class. You will include 2 things in your project, the elements properties and the elements history and use.
1. Element Properties
One type of information you will find about your element is the element’s various chemical and physical properties. Several examples of properties are:
boiling point, melting point; atomic number, average atomic mass, isotopes and percent abundance; state of matter, color, texture, brittle/ductile, conductor of electricity and/or heat, insulator; radioactivity; metal/nonmetal/metalloid; ions the element forms; reactivity with acids, bases, oxygen, metals; alkali metal, alkaline earth metal, etc.
You need not include all of the above information; different sources will have different pieces of information about a particular element. There may be some properties of the element that have NOT been listed above. You can include these, too.
v Include 10-15 properties of your element!
2. History / Uses of the Element
The second type of information you will find about your element involves man’s relationship to the element. Here, you may include facts about the discovery of the element.
Include the following:
1. What person/people discovered it?
2. Where and when was it discovered?
3. In what country?
4. Is there a story behind the identification or discovery of the element?
You should also include information about how humans interact with the element.
5. Where is the element found in nature?
6. Is it found in ores or minerals? Is it found in the sea or in the air?
7. Do certain plants or animals have high concentrations of this element?
8. What processes must we perform to acquire samples of the element?
9. What is the element used for?
A Final Word About What Information NOT to Include in Your Project
DO NOT copy information word for word from a source or include information that you know nothing about. For example, unless you know the meaning of the following passage, you should not include it or anything like it in your final draft.
“In accordance with valence-shell electron pair repulsion theory, carbon has bond angles of approximately 109.5o. As a result of its symmetric structure, carbon forms a backbone for molecules such as alkanes and alkenes. Since these long-chain molecules are usually nonpolar in nature, the only forces acting between such molecules are Van der Waals forces.”
You NEED NOT include the sources of information on your project.
Sources
There is no limit to the sources you can use. You may use books, encyclopedias, textbooks, videos, newspaper articles, etc. Keep a bibliography/ list of sources that you will attach to this assignment.
We will spend 2 days doing research on Chrome Books.
Some of you who are familiar with the Internet may wish to use it as a source of information. You will find plenty of information if you do a search on periodic table.
What you will hand In
- Information sheet with Physical and Chemical Properties and History of Element
- You will also present to the class some of this information
Assessment
