Overview: Can you feel the pressure being exerted on your body as you read this? Depending on your altitude you have at least 14.6 pounds of air pressing down on every square inch of your body. Air pressure at sea level is 14.6 lbs. per square inch and as your altitude increases the pressure decreases. We will be discussing and demonstrating the effects of air pressure on such common items as hard boiled eggs, balloons, water, canned soda, 3 by 5 cards, panes of glass and ping pong balls, to name just a few. NATURE OF SCIENCE STANDARDS Indicator 1: Understand the nature and origin of scientific knowledge. Note: Mastery is not expected at these grade levels. Indicator 2: Apply the skills necessary to conduct scientific investigations. Note: Mastery is not expected at these grade levels. PHYSICAL SCIENCE STANDARDS 3-5 Indicator 1: Describe structures and properties of, and changes in, matter. 3.P.1.1. (Comprehension) Describe physical properties of matter using the senses (touch, smell, etc.). 4.P.1.1. (Comprehension) Describe observable physical changes and properties in matter. 4.P.1.2. (Analysis) Explain how some physical properties remain the same as the mass is changed. 4.P.1.3. (Comprehension) Differentiate between the states of matter caused by changes in temperature using water. 5.P.1.1. (Knowledge) Define matter on the basis of observable physical properties. Indicator 2: Analyze forces, their forms, and their effects on motions. 4.P.2.1. (Application) Demonstrate how forces act over a distance. 5.P.2.1. (Knowledge) Identify forces in specific situations that require objects to interact, change directions, or stop. Indicator 3: Analyze interactions of energy and matter. 4.P.3.3. (Application) Use magnets, electromagnets, magnetic fields, and compasses to explore magnetic energy. SCIENCE, TECHNOLOGY, ENVIRONMENT, AND SOCIETY STANDARDS Indicator 1: Analyze various implications/effects of scientific advancement within the environment and society. 4.S.1.1. (Comprehension) Describe how people continue to invent new ways of doing things, solving problems, and getting work done. Indicator 2: Analyze the relationships/interactions among science, technology, environment, and society. 5.S.2.1. (Evaluation) Explain the interrelationship of populations, resources, and environments. NATURE OF SCIENCE STANDARDS Indicator 1: Understand the nature and origin of scientific knowledge. 8.N.1.1. (Comprehension) Differentiate among facts, predictions, theory, and laws/principles in scientific investigations.
Indicator 2: Apply the skills necessary to conduct scientific investigations. Note: These skills should be taught and practiced in grade-level study of Physical, Life, and Earth/Space Science although mastery is not expected at these grade levels. 6.N.2.1 (Application) Pose questions that can be explored through scientific investigations. 7.N.2.1. (Application) Conduct scientific investigations using given procedures. PHYSICAL SCIENCE STANDARDS 6-8 After careful consideration of current research and input from educators throughout the state, the Committee revised former standards to facilitate effective instruction and student mastery. Grade six standards emphasize an integration of Physical, Life, and Earth/Space Science. Grade seven standards emphasize Life Science. Grade eight standards emphasize Earth/Space Science. Nature of Science and Science, Technology, Environment, and Society standards continue to emerge over these grades. Indicator 1: Describe structures and properties of, and changes in, matter. 6.P.1.2. (Application) Classify matter based on physical and chemical properties. 6.P.1.3. (Comprehension) Describe phase changes in matter differentiating between the particle motion in solids, liquids, and gases. 8.P.1.3. (Comprehension) Compare properties of matter resulting from physical and chemical changes. Indicator 2: Analyze forces, their forms, and their effects on motions. 6.P.2.1. (Comprehension) Describe how push/pull forces acting on an object produce motion. Indicator 3: Analyze interactions of energy and matter. 6.P.3.1. (Comprehension) Identify types of energy transformations NOTE: Each site must audio mute upon connecting to the session to prevent voice activated moving of the cameras from site to site. |
