A. A working definition of matter is that it takes up space, has mass, and has measurable properties. Matter is comprised of atomic, subatomic, and elementary particles.
B. Electrons are key to defining chemical and some physical properties, reactivity, and molecular structures. Repeating (periodic) patterns of physical and chemical properties occur among elements that define groups of elements with similar properties. The periodic table displays the repeating patterns, which are related to the atom's outermost electrons. Atoms bond with each other to form compounds.
C. In a chemical reaction, one or more reactants are transformed into one or more new products. Many factors shape the nature of products and the rates of reaction.
D. Carbon-based compounds are building-blocks of known life forms on earth and numerous useful natural and synthetic products.

Virtual Manipulatives
Students will pump gas molecules to a box and see what happens as they change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.
- Students can predict how changing a variable among pressure, volume, temperature and number influences other gas properties.
- Students can predict how changing temperature will affect the speed of molecules.
- Students can rank the speed of molecules in thermal equilibrium based on the relative masses of molecules.
Type: Virtual Manipulative
Explore pressure under and above water. See how pressure changes as one change fluids, gravity, container shapes, and volume.
With this simulation you can:
- Investigate how pressure changes in air and water.
- Discover how to change pressure.
- Predict pressure in a variety of situations.
Type: Virtual Manipulative
Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time.
