Unit 3: Matter
ESSENTIAL IDEA:
- 3.1 - Atomic Structure
- 3.2 - Mixtures & Solutions
ESSENTIAL QUESTIONS
- 3.1 - Atomic Structure
- Why do we use models in science?
- What are the component particles that scientists have discovered within atoms?
- What is the current model of the atom, and how was it developed?
- 3.2 - Mixtures & Solutions
- What forms can matter take and how are the particles arranged?
- What is the difference between matter and non-matter?
- How does temperature affect the movement of the particles as they move through each state of matter?
- How are elements and compounds related to one another?
UNDERSTANDINGS / APPLICATIONS / SKILLS / NATURE OF SCIENCE:
- 3.1 - Atomic Structure
- 3.1.NOS: Scientists have shared their discoveries and collaborated with one another for centuries to better understand the world.*
- 3.1.U2: Atoms are the smallest unit of matter
- 3.1.U3: The periodic table is a collection of all the elements on earth.
- 3.1.S1: The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules.
- 3.1.A1: The different isotopes of an element are identified by its mass number and number of neutrons.
- 3.1.S2: Atoms and their subatomic particles can be represented by drawing Bohr models.
- 3.2 - Mixtures & Solutions
- 3.2 U2: The structures of materials determine their properties.
- 3.2 S1: Heating and cooling curve models are used to represent physical changes in states of matter.
- 3.2 U3: Matter of any type can be subdivided into particles and can be classified as elements, compounds, and
mixtures, depending on how its particles are arranged.
- 3.2.A1: Life would not be possible if solutions did not exist.
- 3.2A2: One’s body is composed of many different solutions which allows it to function properly.*
