Stage 1: Identifying Desired Results
Established Goals:
Maine Learning Results: Science and Technology-D. Physical Science
D3. Matter and Energy
Grades 9-Diploma
Students describe the structure, behavior, and interactions of matter at the atomic level
and the relationship between matter and energy.
Benchmarks for Science Literacy pg 75
Students learn the properties of materials, Changes of state, and temperature effects.
Students are gradual introduced to the complexity of atomic structure, and express the
history of Chemistry today.
Students will understand that:
Atoms are the particles that make up matter.
Atoms are composed of measurable components, with charges and mass.
Isotopes have differing numbers of neutrons.
There are nuclear forces that keep atoms together.
Atoms can transfer or share electrons.
The outer electrons govern chemical properties.
Elements are made up of a single type of atom.
Solids, liquids, and gases differ in the distances and angles between molecules or atoms
and the energy that binds them together.
Essential questions:
What is matter made of?
How are atoms structured?
How are isotopes formed?
Why are atoms held together?
How do atoms interact?
What effect do the outer electrons have on atoms?
Why are elements made up of a single type of atom?
How do solids, liquids, and gases differ?
Students will know:
Vocabulary:
Atoms, Nucleus, Protons, Electrons, Electron Configuration, Mass, Isotopes, Radioactive
Isotopes, Decay, Elements, Molecules, Properties, Concentration, Pressure, and
Temperature.
Concepts:
Atoms are composed of protons, neutrons, and electrons, A system usually has properties
different from its parts, Atoms interact by transferring or sharing electrons, Different
energy levels are associated with different configurations of atoms and molecules, Rates
of reactions among atoms and molecules depend on how often they encounter one
another.
Students will be able to:
Explain the discovery of the atom and its parts.
Illustrate the components of atoms and molecules and how they interact.
Use their knowledge of isotopes to determine their half-life.
Consider the effect of the outer electrons on how atoms interact.
Realize how solids, liquids, and gases differ.
