Timeline
Unit 7
Recommended number of
sessions: 8 sessions - 90
minutes each
Equilibrium
Subunits: a. equilibrium; b. reaction rates; c. acid/ base chemistry
Stage 1 – Desired Results
Established Goals
(Non-negotiables) (Washington State Content Science
Standards)
9-11 PS2I
The rate of a physical or chemical change may be affected
by factors such as temperature, surface area, and
pressure.
9-11 PS2H
Solutions are mixtures in which particles of one substance
are evenly distributed through another substance. Liquids
are limited in the amount of dissolved solid or gas that
they can contain. Aqueous solutions can be described by
relative quantities of the dissolved substances and acidity
or alkalinity (pH).

Transfer
Students will be able to independently use their learning to …
 To alter the rate of a chemical reaction intentionally based on many factors.
Meaning
Understandings (Non-negotiables)
Students will understand that …


Predict the result of adding increased
amounts of a substance to an aqueous
solution, in concentration and pH.*b
Recommended Essential Questions
Students will keep considering …
 What can I do to make a reaction go faster?
 How does pH affect living things?
Predict the effect of a change in temperature,
surface area, or pressure on the rate of a
given physical or chemical change.*b
Acquisition
Students will know …
 Le Chatelier’s Principle
 The various factors that influence chemical equilibrium, including
concentration
 The uses of catalysts and some common catalysts
 The relationship between collisions between reacting particles and
rate of reactions
 The uses of buffers to maintain equilibrium
 That activation energy is required
 Identify the common uses of acids and bases
