PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures

PS 1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

PS 1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.

PS 1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved

PS 1-6: Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.

LS1-6: Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms

LS 1-7: Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism

Chemistry Principles:

1. Matter is made of atoms that combine to make molecules
2. During a chemical reaction, bonds are broken and reattached to make new molecules.
3. Matter is neither created or destroyed
4. Photosynthesis is a chemical reaction where plants use carbon dioxide and water with energy from the sun to make glucose and oxygen.
