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
