Students will explore the building blocks of matter and will master the following competencies upon completion of the program:
• Conclude there are more than 100 known elements that combine in a multitude of ways to produce compounds which account for all living and non-living substances.
• Demonstrate that atoms combine to form molecules and molecules formed from different atoms combine to form compounds.
• Recognize a substance has characteristics, such as density, viscosity, boiling point, and solubility, all of which are independent of the amount of the sample.
• Identify the state of matter represented by a molecular diagram.
• Identify examples of compound molecules.
• Explain how changes in states of matter are the results of changes in kinetic energy.
• Explain the relationships between temperature, kinetic energy and states of matter.
Students will study physical and chemical changes and will learn to:
• Differentiate between a physical change in which matter changes state or form and a chemical change in which one or more new substances are formed.
• Conclude a change in the state of matter of a substance is the result of a change in kinetic energy.
• Conclude that energy in a system is conserved and may change from one form to another.
• Identify examples of physical and chemical change.
In addition, atmospheric properties will be explored and students will be able to:
• Determine there are a number of characteristic properties of air including mass, weight, density, volume and pressure.
• Discover air pressure is not constant, varies with altitude, is inversely proportionate to velocity and varies with changes in kinetic energy.
• Identify gases and their proportions that make up the Earth's atmosphere.
• Categorize air as a fluid, similar to the ocean, based on observable properties.
• Explain the relationship between air pressure and temperature.
• Apply the principle that air exerts pressure in all directions.
• Identify the density of Earth's atmosphere.
