Unit: Chemistry (Chemical Rxn/Formula)
Grade: 8
Stage 1: Desired Results
Enduring Understandings
Students will understand that…clues that help you determine that a
Everything is either made up of matter and energy.
There are determine patterns of physical and chemical interactions based on properties of matter.
Essential Questions
Build It Up Questions
How can I describe a chemical reaction?
How is energy involved in chemical reactions?
What are clues that help you determine that a chemical
reaction has taken place?
How is energy involved in a chemical reaction?
What factors will affect the rate of chemical reactions?
What chemical reactions relate to everyday life?
What kind of information is represented by a chemical
equation?
What information is conveyed by a chemical formula?
Knowledge & Skills (8th)
(SAISD scope & sequence, TEKS etc.)
8.9A – demonstrate may react chemically to form new
substances
8.9 C – recognize importance of formulas & equations to
express what happens in a chemical reaction
8.10C – identify & demonstrate that loss and gain of heat
energy occurs during exothermic & endothermic chemical
reactions
Prior Knowledge (7th & 6th)
(SAISD scope & sequence, TEKS etc.)
Skill
Vocabulary
Stage 2: Assessment Evidence
Performance Task:
(be sure to create an assessment rubric for the performance task as well)
Goal = how chemical reactions work and how energy is involved?
Role = Intern
Audience = younger grade level student
Situation = written, oral, visual presentation
Product = scenario
Standard = Rubric
Other evidence:
(quizzes, tests, academic prompts, self-assessments, etc.
note – these are usually included where appropriate in Stage 3 as well)
Stage 3: Learning Activities
(Steps taken to get students to answer Stage 1 questions and complete performance task)
Lab safety and scientific method
Chemical reaction stations day
* Measurements
* Density
*Clues to reaction - express physical prop of materials, describe reaction of reaction
*
Chemical formula Jacks – presenting formula on white board, student will collect the appropriate color / number of jacks
corresponding to the given formula. Introduce coefficient and subscript in relationship to chemical formulas.
Balanced or Unbalanced? (M &M’s) – students look at chemical equations to see if the equation is balanced or unbalanced by
counting the number of elements on the reactant and product side of the equation.
Endo & Exothermic reactions
Guided Labs – expressing
Conduction = hot water add spoon what happened to the temp of the spoon
Convection = beaker on hot plate with water add in aluminum foil ball and watch it move in a circle pattern
Radiation =flood light moving heat to hand. Heat moves through space.
