Chemistry Lesson 1

Lesson 1 of 15
Lesson Title:
AZ Teaching Standard: Science C1:Properties and Changes of Properties in Matter
PO1: Identify that matter is made of smaller units called molecules and atoms
Lesson Outcome: TSW identify matter.
Evidence: Graphic organizer that classifies 3 examples of matter into solids, liquids or gases.
Big Idea: Interactions Cause Change
Materials: Science book, meta-cognitive model on classifying objects into each state of matter; graphic
TSW define
states of
matter; liquid,
solid, gas.
TSW classify
different items
into its state of
Teacher Actions
Teacher will use a thinking map to
define each state of matter.
Teacher will remind students to
write definitions in own words.
Teacher will randomly call on
students to share out definitions
and record other definitions.
Teacher will model classifying
different objects into the
corresponding state of matter.
Model will include labels such as
liquid, movement, gas, unseen,
solid, something to hold.
Guided Practice: Working in groups
students will be given the following
states of matter to classify: Helium,
soda, paper clip. Using a graphic
organizer and science book,
students will classify each of them
using justification.
Independent Practice: Students
will determine 3 objects for each
state of matter. When they have
classified an object, they will justify
why they classified each object as
they did.
Participants Actions
√ for
Students will take notes on the
different states of matter.
Students will share out how they
defined each state of matter.
Teacher will
circulate and
make sure
students have
thinking map
completed in own
graphic organizer.
Working in groups and then
individually students will justify
classifying objects into each state
of matter using the graphic
organizer and science book.
