Overview
Students investigate basic concepts
of chemistry – properties of mixtures and solutions,
dissolving a solid in a solvent, concentration and
saturation of a solution, evidence of chemical reaction,
evaporation, and crystal formation. Students
gain experience with laboratory tools and techniques.
Learning Expectations:
Understand that matter can be classified according to properties
and type.
Understand the atomic nature of matter.
Understand that when substances
interact to form new substances, mass is covered.
- Describe concepts about the structure of matter.
- Gain experience with the concepts of mixture and solutions.
- Gain experience with the concepts of concentration and saturation.
- Gain experience with the concept of chemical reaction.
- Apply an operational definition to determine the relative
concentrations of solutions.
- Use group problem-solving techniques to plan investigations.
- Use measurement in the context of scientific investigations.
- Apply mathematics in the context of science.
- Acquire vocabulary associated with chemistry and the periodic
table.
- Be introduced to the concept that all matter is made of
very small particles called atoms and that atoms combine to
form molecules.
- Use scientific thinking processes to conduct investigations
and build explanations: observing, communicating, comparing,
organizing, and relating.
- Work collaboratively and use tools and scientific techniques
to make better observations.
- Understand science safety and
follow safe practices during investigations.
Assessments:
- Lab experiments
- Performance assessments
- Reflective journals
- Teacher created assessments
- End of unit projects
- Rubrics
- Checklists
- Homework/Class work
- Teacher observations

Content: Physical
Science
Develop students’ understanding of
properties of matter and changes in properties of matter.
- Substances have characteristic properties,
such as solubility. A
mixture of substances often can be separated into the original
substances using one or more of the properties.
- Substances react chemically in characteristic ways with
other substances to form new substances.
- More than 100 known
elements (92 of them naturally occurring) combine in a multitude
of ways to produce compounds, which account for the living
and nonliving substances in our world.
