Chemistry
Chemistry is the study of matter and how matter changes. Throughout this unit students will be studying the following based on Grade Level Expectations:
- Identify that elements and compounds are pure substances that have characteristic properties.
- Describe physical and chemical properties of pure substances
- Describe evidence that supports the theory that mater is composed of moving particles too small to be seen
- Using the Kinetic Theory Model, illustrate and account for the physical properties of a solid, liquid, or gas in terms of the arrangement & motion of the molecules
- Use the Kinetic Theory Model to explain changes in shape, volume, and viscosity
- Predict the effect of energy transfer on physical properties of a substance as it changes from a solid, liquid, or gas
- Identify more than 100 known elements that exist
- Provide evidence that mass is conserved during a chemical change in a closed system
- Recognize describe how chemical energy in stored in chemical compounds
