TEKS
addressed:
·
Science
is a way of learning about the natural world. Students should know how science
has built a vast body of changing and increasing knowledge described by
physical, mathematical, and conceptual models, and also should know that
science may not answer all questions.
·
demonstrate
safe practices during field and laboratory investigations
·
collect
data and make measurements with precision
·
express
and manipulate chemical quantities using scientific conventions and
mathematical procedures such as dimensional analysis, scientific notation, and
significant figures
·
demonstrate
the use of symbols, formulas, and equations in describing interactions of
matter such as chemical and nuclear reactions
The Lesson:
Students
will explore Stoichiometry with a hands on lab, introductions
to types of problems, worksheets, and quizzes to reinforce the learning.
Students will be able to:
·
Calculate
the amount of reactants required or product formed in a nonchemical
process.
·
Interpret
balanced chemical equations in terms of interacting moles, representative
particles, masses, and gas volume at STP.
·
Construct
mole ratios from balanced chemical equations and apply these ratios in
mole-mole stoichiometric calculations
·
Calculate
stoichiometric quantities from balanced chemical equations using units of mole,
mass, representative particles, and volumes of gases at STP.

Explore: Quantitative Analysis Students will use the results of the experiment
and with the data collected the students will use Stoichiometry to evaluate
their results Questions |

Explain: Mini lectures on the types of
problems Students will
see that by simply using the given information with the mole ratios from a
balanced chemical equation they can Questions |
Students
actively participate by giving answers as the problems are demonstrated. Students answer examples on the notes. |

Extend / Elaborate: Apply to project Students can
now apply their knowledge of Stoichiometry to the project and allow for
deeper understanding of the reactions taking place. |
Students see
that they can use mole ratios to determine how much product could be made if
certain chemicals mix. |
