Overview: Nitrogen gas is the most abundant gas in the atmosphere. When it is compressed and cooled, it turns to a liquid, which boils at 250 degrees below zero. Discover the science behind Cryogenics, as we experiment with liquid nitrogen, by observing the effects of super cooling and the changing states of matter. Observe objects changing from one state of matter to another and back again. The student will observe changes between the solid, liquid and gas states of matter as we use items such as racquet balls, balloons, metals and super conductors.

NATURE OF SCIENCE STANDARDS
6-8  

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 3: Analyze interactions of energy and matter.

6.P.3.1. (Comprehension) Identify types of energy transformations.

SCIENCE, TECHNOLOGY, ENVIRONMENT, AND SOCIETY STANDARDS
6-8  

Indicator 1: Analyze various implications/effects of scientific advancement within the environment and society.

6.S.1.1. (Comprehension) Describe how science and technology have helped society to solve problems.

7.S.1.1. (Comprehension) Describe how science and technology are used to solve problems in different professions and businesses.

8.S.1.1. (Comprehension) Describe how science and technology have been influenced by social needs, attitudes, and values.

NOTE: Each site must audio mute upon connecting to the session to prevent voice activated moving of the cameras from site to site.
