Tenth grade Science topics covered
Atomic structure
- Use the periodic table as a model to predict the relative properties of elements
- Construct an explanation for the outcome of a simple chemical reaction based on the outermost electron states
- Plan and conduct an investigation to gather evidence for the atomic and molecular structure of pure substances
- Develop models to illustrate the changes in the composition of the nucleus
Chemical bonding
- Use the periodic table model to predict properties of elements and compounds
- Construct a model to explain how the structure of ionic bonding results from electrostatic attraction
- Develop and use a model of a simple covalent molecule
- Communicate scientific and technical information about the molecular structure of synthetic and natural materials
Chemical reactions and stoichiometry
- Construct and revise an explanation for the outcome of a simple chemical reaction
- Develop a model that predicts and describes changes in particle motion, temperature, and state
- Apply mathematical representations of conservation of mass to various chemical reactions
- Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction
Energy in chemical processes
- Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states
- Design a solution to a complex real-world problem by breaking it down
- Develop and use a model of two objects interacting through electric or magnetic fields
- Plan and conduct an investigation to examine the relationships among temperature, heat transfer, and efficiency of an energy conversion device
