Storyline Narrative 6.2.1

SEEd Standard 6.2.1 asks students to develop and use a model to show that molecules are made of different kinds, proportions, and quantities of atoms. Students should understand that there are differences between atoms and molecules and that certain combinations of atoms form specific molecules.

 

To engage students in this storyline, students look for patterns by observing a system of a patch of grass, a blade of grass, blade of grass under a magnifying glass, and a blade of grass under a microscope. Students ask questions about what else could be going on in the blade of grass on a scale that is unobservable to the naked eye. Students reason that all living and nonliving things are made up of smaller particles that we can't see called atoms. Students read an article about atoms and molecules. Students discover by observing patterns and characteristics that certain combinations of atoms make up all the molecules that make up all matter. Students create models of different types of simple molecules as evidence that molecules are made of different types and quantities of atoms. Proportional reasoning is also emphasized. Students investigate the structure of the airthat they breathe and ask, "Is it the same year round?" Students are left wondering how molecules are organized in the different states of matter that make up our world.

Episode 1

Question

How does looking at the natural world using different scales affect what we know?

Snapshot

Students look for patterns by observing a patch of grass, a blade of grass, a blade of grass under a magnifying glass, and zoomed in under a microscope.

Conceptual Understandings

Living and non-living things are made up of smaller particles that we can’t see with the naked eye called atoms. Atoms make up molecules.

 

How do atoms and molecules make up matter?

How do atoms and molecules make up matter?

Conceptual Understandings

Atoms and molecules combine in two different ways: two or more of the same atom, or combinations of different kinds and quantities of atoms. Both are considered molecules and makeup all matter. All living and nonliving things are made up of atoms that are organized in different ways.

How are molecules organized in the states of matter?

Snapshot

Students looks for patterns in a variety of atoms and molecules. Students sort atoms and molecules into different groups and explain their patterns. Students create models of molecules based on the patterns they have identified.

Episode 2

Question

How do atoms and molecules make up matter?

 

Episode 3

Question

What is the air made up on and in what percentages?

Snapshot

Students will apply scale, proportion and quantity to the substances in the air.

Conceptual Understandings

Even though we cannot see the air it is made of different
substances. These change throughout the year due to air pollution. How can we accurately
measure at this scale?
