Notes on Layered Curriculum: 

1. I expect students to be working on this unit at all times while in class.
2. All PACT Coach Activities (Discussion Question and Lesson Review) are to be copied and answered in full.  No credit will be given for partial work.  Be prepared to answer at least one question at your oral defense.
3. Use the checklist to keep track of your work.  You should bring all Cornell Notes to Mr. Hodge when completed.  You will defend your learning by answering some questions from Mr. Hodge.
4. Students should keep all work in their notebook.  Mr. Hodge will provide a folder at the end of the unit so students can place their work in their portfolio.
5. Keep up!  Once you get behind, it becomes very hard to catch up.  If you are out, you have this sheet, and you can work on any work you have not completed.  Then, upon your return, check with another student for your work.  Also, check the folders in the red hanging folder holder for worksheets.

 
 
 

C Layer Activities 

      Items that are starred (µ) are required and will be done together in class.  These items will require an oral defense of student learning before the grade is recorded.

      Other items may be done in class, but may also require time (sometimes substantial amounts) outside of class in order to complete them.  ALL C LAYER WORK MUST BE COMPLETED BEFORE ATTEMPTING ANY B OR A LAYER WORK (NO EXCEPTIONS).  You may do any B Layer Activity that relates to the individual lessons.  Once you complete those, you may begin working on an A Layer activity that relates to the individual lessons.

2. Choose a synthetic element and write a biography of the element.  Include information about the element’s name, location of the synthesis research, and the people responsible.
3. Research and report on models of the atom from the time of the ancient Greeks until the present. (You may make a poster or display of the information.)
4. Make a web page, PowerPoint presentation or 3-D bulletin board to teach others about the atom, atomic structure and the periodic table.
5. Select group 1, Group 2, Group 17 or Group 18 from the periodic table.  Find out the properties and uses of the elements in the group and determine what the elements have in common.  Prepare a poster or presentation that shows what was learned so that the information can be shared with the rest of the class.
6. Research and make a timeline that shows the development of the modern atomic theory, identifying on the timeline the contributions of key physicists and chemists. Include information about other events in history that happened around these key dates.  Create the timeline on a poster.
7. Your Idea (Approved by Mr. Hodge)

 
 

A Layer Activities (Choose One – 30 Points) 

1. Our society is rapidly consuming raw materials that are nonrenewable. Discuss whether we should rely on materials scientists to develop new materials to replace older ones that are no longer available or consume and discard currently available materials more wisely. Is every material replaceable?
2. Discuss what types of materials are most important to recycle. Debate whether recycling should be made the law nationwide. Is the expense of enforcing such a law justified or is the money better spent on other social or scientific programs?
3. Given the high quality and ready availability of substitutes, debate whether rare materials such as gold or diamonds should be used for jewelry and art or saved solely for technology and industry.
4. Discuss how our global society would change if the technology to change one element into a different element were developed. Is this a technology that, if developed, should be made public?
5. One area of great advancement in materials science is the area of medicine. Artificial joints are available, and scientists are currently developing artificial skin and blood. Discuss whether there should be limits placed on the development of physiological substitutes. Can you think of any reasons why advances in this area should be controlled?
6. Many of the greatest advances in materials science have been made accidentally. In light of this, discuss the value of following the scientific method versus chance. Is there ever room for chance when strictly adhering to the scientific method?
