“A” level assignments (Choose one only)
You may answer any one of the following question in a format of your choosing. Some examples might include the following:

3-2. 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?
3.3. 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?
3.4. 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.
3.5. 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?
3-6. Research whether or not fluoride should be in public drinking water. Fluoride is an element found that is helpful in strengthening teeth and preventing tooth decay. Some groups believe fluoride is more dangerous than helpful. You need to choose a position and support it with data and facts.
