Abstract
Instructor will provide students with a recipe for making their
product. However, the recipe will give no specific amounts of
reactants. The recipe will provide general procedure and lab safety
considerations. After recieving their recipes the students will
research the physical properties, chemical properities, and safety
considerations of the reactants and products.
Lesson fundamental understandings:
Essential
Questions: 1. What are the physical and chemical
properties of the reactants and products?
2. How will one
redefine the qualities of the desired products?
Standards
National Standards Scientists usually
inquire about how physical, living, or designed systems function.
Conceptual principles and knowledge guide scientific inquires.
Historical and current scientific knowledge influence the design and
interpretation of investigations and the evaluation of proposed
explanations made by other scientists.
State Standards Nevada: 2.12.1
Investigate and describe intrinsic and extrinsic physical properties
of matter 19.12.1 Identify and determine the credibility of sources
of information beasd on the techniques used to gather that
information 22.12.3 Discuss scientific topics by restating or
summarizing accurately what others have said 24.12.2 Use the
information found in materials safety data sheets (MSDS) to handle,
store, and dispose of chemicals properly 24.12.4 Maintain a
permanent record of procedures, data, analyses, decisions and
understandings of scientific investigations
Lesson
Prerequisite Skills
1. Students must have a knowledge of chemical bonding. 2.
Students must be able to write formulas and equations. 3. Students
need to be able to use the internet to conduct research of
properties.
Teacher
Information/Situations/Setting/Time Time Frame: One
day
Materials/ Resources: Labs giving the reactants to make the
specfic students' products.
Pre-lesson Preparation: Instructor
should reserve computer access prior to class.
NOTE: The
instructor may again choose to do this portion of the project
outside the stoiciometry unit timeframe. Suggestion: Do this portion
during the Chemical formulas and compounds unit.
Assessment
1. Journal enteries for step # 2 of project
2. Worksheet and
evaluation for step # 2
Student Activity/Tasks 1. Students will
given a "recipe" for making their product, which has no specific
amounts of reactants.
2. Students research the properties of the
reactants and products using the internet.
3. Students research
safety considerations of reactants and products.
4. After
researching students may need to redefine qualities of product based
on properties' research.
Enrichment/Alternate Activity:
For research students may use the libary
Cross-Curricular:
English - research
Technology
Requirements/Tools/Materials
Internet - world wide web
