Name of Lesson/Unit: Chemical Reactions: Conservation matter
Grade Level: 8
Prepared by:
Section 1: Lesson Summary
Students will explore chemical reactions by creating a model that will show how matter is
conserved. They will first research their choice of chemical reaction, from an available list.
They will write their findings.
Topic:
NGSS Performance Expectation:
MS-PS1-5 Law of Conservation of matter and on physical models or drawings, including
digital forms, that represent atoms.
MS-LS1-7 Describing that molecules are broken apart and put back together and in this process
energy is released.
Crosscutting Concept
Matter is conserved due to atoms conserved in physical and chemical processes.
Engineering Practices
Develop a model to describe phenomena
Develop a model to describe unobservable mechanisms.
Common Core State Standards (Reading)
RST.6-8.7 Integrate quantitative or technical information expressed in words in a text with a
version of that information expressed visually.
Common Core State Standards (Writing)
Students will research reactions and how matter is conserved and it applies to our society.
Common Core State Standards (Math)
6.SP.B.5 Summarize numerical data sets in relation to their context.
Current CA Science Standards
5b. Atoms explain the conservation of matter: In chemical reactions the number of
atoms and total mass stay the same.
Objective of the Lesson or Unit:
Demonstrate how the number of atoms, properties, and mass won’t change.
How is this objective relevant to students?
To show how this phenomenon explains the formation of many of our natural and unnatural
resources.
Lesson Plan Template
Culminating Assessment (How will you know students have met the Performance Expectation?)
Describe the assessment and attach a copy.
Students will have a model that shows how the molecules are reorganized going from reactants to
products.
What has been taught in my class to prepare students for this topic?
The atom structure, their role in the periodic table and how molecules are formed.
Description of the Lesson/Unit (Use the following Table)
With 5 E and How
Short description of activity
People Learn in Mind!
Engagement
Exploration
Explanation
Elaboration
Students research a chemical
equation of their choice.
Use of chem. Models to show
the configuration of molecules
in the equation.
Students will explain the
equation as balanced or
unbalanced. By showing the
moles on the reactants and
products.
Purpose/Intention for the activity or
Key Learning
 How does this activity build
student knowledge and skills
towards meeting the
Performance Expectation?
 Identify at least 1 Practice
How do chemical reactions depict the
Conservation of Mass theory?
Students will use models to depict how
atoms interact with each other
Students will explain the arrangement
and support with evidence the
Conservation of Mass theory.
Students by choosing their own
equation are exploring their interest
and applying it to the content being
learned
Evaluation
Section 2: Laboratory/ Hands-on Lesson
Content Objective:
Using a chemical reaction to show how molecules are arranged as reactants and rearrange as
products.
Language Objective:
Use adjective to describe the reactant-product relationship within the chemical reaction.
Assessment: How will I know students met the objective?
Students will have a table showing each atom and it’s number count.
Lesson Plan Template
Rubric:
4:
* Did the student depict the atoms in the reaction?
*Did the student depict the correct number of atoms in the tables?
*Use of adjectives to describe the relationship found in this reaction (ie, equal, same, form,
move, etc)
*Students in their conclusion questions demonstrate understanding of the Conservation Law
Description of lesson:
Students will use ball and stick models to form the reactants.
They will then create a table showing the number of atoms, on a paper.
Then rearrange them into the products. They will then create another table showing the number,
of atoms in this section, on a separate paper.
Time required for the lesson:
1-2 class period
