                                     Assignment Sheet
Learning Goals:
    1. Identify evidence of chemical reactions and demonstrate how chemical equations are
       used to describe them.
    2. Recognize matter is conserved during a chemical reaction.
    3. Determine the molar proportions in a chemical reaction and use them to predict the mass
       of product produced in a simple chemical reaction that goes to completion.
    4. Analyze evidence for the law of Conservation of Energy in chemical reactions.
    5. Describe how electrical energy can be produced in a chemical reaction.
Level A – Knowledge and Comprehension
        Students will be required to complete all the assignments listed under each learning goal.
Because of the nature of these topics we need to work together as a class on most assignments.
We will have more labs for this unit, but we will also have more worksheets that will allow us to
practice the concepts.
Learning Goal 1 – Description of a Chemical Reaction
    1. Note-taking Activity: Listen to a brief presentation and take notes on the entire
        presentation in your chosen format.
    2. Brochure Activity: Create a brochure that defines a chemical reaction, the evidence of
        a reaction, the types of reactions, and the parts of a chemical equation. Make sure to
        include colored and labeled diagrams and written descriptions.

Learning Goal 2 – Conservation of Mass
   3. Note-taking Activity: Listen to a brief presentation and take notes on the entire
       presentation in your chosen format.
   4. Worksheet Activity: Complete the Conservation of Mass worksheet packet.

Learning Goal 3 –Molar Proportions
   5. Note-taking Activity: Listen to a brief presentation and take notes on the entire
       presentation in your chosen format.
   6. Worksheet Activity: Complete the Mole worksheet packet
Learning Goal 4 – Conservation of Energy
   7. Note-taking Activity: Listen to a brief presentation and take notes on the entire
       presentation in your chosen format.
   8. Worksheet Activity: Complete the Conservation of Energy worksheet packet
Learning Goal 5 – Electrical Energy
   9. Note-taking Activity: Listen to a brief presentation and take notes on the entire
       presentation in your chosen format.
   10. Art Activity: Create a poster explaining an electrochemical cell. Explain half-reactions
       and electron transfers. Include a labeled diagram of an electrochemical cell. Make sure
       to include color and written descriptions.

                   Essential Questions
Learning Goal #1

   1. Generalize evidences of chemical reactions.
   2. Compare the properties of reactants to the properties of products in a
      chemical reaction.
   3. Use a chemical equation to describe a simple chemical reaction.

Learning Goal #2

   4. Recognize that the number of atoms in a chemical reaction does not
      change.
   5. Determine the molar proportions of the reactants and products in a
      balanced chemical reaction.
   6. Investigate everyday chemical reactions that occur in a student's home
      (e.g., baking, rusting, bleaching, and cleaning).

Learning Goal #3

   7. Using data from quantitative analysis identify evidence that supports the
      conservation of mass in a chemical reaction.
   8. Use molar relationships in a balanced chemical reaction to predict the
      mass of product produced in a simple chemical reaction that goes to
      completion.

Learning Goal #4

   9. Report evidence of energy transformations in a chemical reaction.
   10. After observing or measuring, classify evidence of temperature change in
       a chemical reaction as endothermic or exothermic.
   11. Using collected data, report the loss or gain of heat energy in a chemical
       reaction.

Learning Goal #5

   12. Using either a constructed or a diagrammed electrochemical cell, describe
       how electrical energy can be produced in a chemical reaction (e.g., half
       reaction, electron transfer).
