6th Grade Science
Lesson: May 15, 2020
Objectives/Learning Targets:
Students will identify chemical properties and changes.
Warm Up - Answer Key
Begin by watching this video clip.
1. Signs of a chemical change:
● The batter took in heat & the baked cake
gave off heat
● The color changed from yellow to golden
brown
● A smell was produced while the cake is in
the oven
● Carbon dioxide was released
● The change is irreversible
2. Answers may vary. Ex: Toasting a slice of
bread, scrambling eggs, cooking chicken
Background Information
Chemical Property:
A property of a substance that describes
how it reacts to other substances and
changes its chemical identity as a result
Examples of chemical properties: toxicity,
combustibility, reactivity with water, acidity
Chemical Change:
A change that is irreversible that changes
the physical & chemical properties of a
substance, creates a new substance
Examples of chemical changes: burning a
match, iron rusting, cooking chicken
Signs that a chemical reaction (change) has occurred:
F- FIZZ
● Formation of bubbles or fizz are a sign of a chemical change.
A- AROMA
● After a chemical change, the smell may change.
R- REPLACEMENT OF COLOR OR REACTIVITY
● A color change or reaction may indicate a chemical change.
T- TEMPERATURE CHANGE
● Exothermic Reaction: Heat Exits, Gets hot! Endothermic Reaction: Feels cold
S- A NEW SUBSTANCE FORMS
● Molecules rearrange and a new substance is present.

Determine if the following are examples of
chemical properties or changes.
Chemical Change
1. A change in the physical and chemical
properties.
2. A new substance is formed.
Chemical Property
1. Indicated how a substance reacts with
something else.
2. Matter will be changed into a new
substance after the reaction.

Practice
Grab your folded piece of paper from yesterday’s lesson. On the blank side,
create a one-pager over chemical properties and changes. Use the directions
below to create your one-pager.
1. Make sure your one-pager has a TITLE.
2. Include four pictures to represent chemical
properties and changes.
3. Include five vocabulary words expressing chemical
properties and changes.
4. Include two questions that you are still wondering
about chemical properties and changes.
5. Connect your one-pager to your life by drawing
something in your home that you can describe its
chemical properties!
