Essential Questions - 21st Century Skills and Readiness Competencies (District):
1a. What patterns of chemical reactions exist?
1b. How are chemical reactions distinguished from nuclear reactions?
1c. How is the conservation of mass exhibited in a nuclear reaction and through the
process of recycling?
2a. What evidence identifies that a chemical reaction has occurred?
2b. How is the Law of Conservation of Mass demonstrated through the balancing of
chemical equations?
2c. How would the equations for a chemical reaction differ from that of a nuclear
reaction?
2d. What are the ways that you can differentiate between different types of chemical
reactions?

replacement reactions?
3b. How are the products of fusion and fission different?
4. What is the relationship between the amount (mass) of products and reactants in a
chemical reaction?
Evidence Outcomes (District):
1. Examine, evaluate, question, and ethically use information from a variety of sources
and media to investigate the conservation of mass and energy.
2. Recognize, analyze, interpret, and balance chemical equations (synthesis,
decomposition, combustion, and replacement) and nuclear equations (fusion and
fission.)
3. Predict reactants and products for different types of chemical and nuclear reactions.
4. Predict and calculate the amount (mass) of products produced in a chemical
reaction based on the amount of reactants.
