Abstract

After making their chemical product, students will make a presentation regarding their product; the class as a whole will compare at least two "brands" of the same product and share their reports with other testers.

Lesson fundamental understandings:
Essential Questions:

1. Is there more than 1 "recipe" or quantity for making something?
Explain your answer.
2. Is there more than 1 technique to making a product? Explain.
3. Would it be truly economical to always purchase a generic product
over a name brand? Defend your answer.
4. Why might one not get 100% yield? Are there specific factors
that cause this?

Standards

National Standards

Scientific explanations must adhere to criteria such as: a proposed explanation must be logically consistent; it must abide by the rules of evidence; it must be open to questions and possible modification; and it must be based on historical and current scientific knowledge. Results of scientific inquiry--new knowledge and methods--emerge from different types of investigations and public communication among scientists. In communicating and defending the results of scientific inquiry, arguments must be logical and demonstrate connections between natural phenomena, investigations, and the historical body of scientific knowledge. In addition, the methods and procedures that scientists used to obtain evidence must be clearly reported to enhance opportunities for further investigation. Technology Standard(s): Standard 4: Technology Communication Tools Students use telecommunications to collaborate, publish and interact with peers, experts and other audiences Standard 5: Technology Research Tools Students use technology tools to process data and report results Information Literacy Standard(s): Standard 1: The student who is information literate accesses information efficiently and effectively Standard 2: The student who is information literate evaluates information critically and competently Standard 3: The student who is information literate uses information accurately and creatively
