Technology & Engineering

  • Society benefits when engineers apply scientific discoveries to design materials and processes that develop into enabling technologies.

    • How do science concepts, engineering skills, and applications of technology improve the quality of life?

Life Science

Earth and Space Science

  • 6 The cosmos is vast and explored well enough to know its basic structure and operational principles.

    • What big ideas guide human understanding about the origin and structure of the universe, Earth's place in the cosmos, and observable motions and patterns in the sky?

      • GLE 0207.6.1 Realize that the sun is our nearest star and that its position in the sky appears to change.

      • GLE 0207.6.2 Make observations of changes in the moon's appearance over time.

  • 7 Major geologic events that occur over eons or brief moments in time continually shape and reshape the surface of the Earth, resulting in continuous global change.

    • How is the earth affected by long-term and short term geological cycles and the influence of man?

      • GLE 0207.7.1 Compare and record the components of a variety of soil types.

      • GLE 0207.7.2 Describe rocks according to their origin, size, shape, texture, and color.

      • GLE 0207.7.3 Differentiate between renewable and non–renewable resources.

  • 8 The earth is surrounded by an active atmosphere and an energy system that controls the distribution life, local weather, climate, and global temperature.

Physical Science

  • 9 The composition and structure of matter is known, and it behaves according to principles that are generally understood.

  • 10 Various forms of energy are constantly being transformed into other types without any net loss of energy from the system.

    • What basic energy related ideas are essential for understanding the dependency of the natural and man-made worlds on energy?

      • GLE 0207.10.1 Explain why the sun is the primary source of the earth's energy.

  • 11 Objects move in ways that can be observed, described, predicted, and measured.

    • What causes objects to move differently under different circumstances?

      • GLE 0207.11.1 Investigate how vibrating objects produce sound.

      • GLE 0207.11.2 Classify sounds according to their loudness and pitch.

  • 12 Everything in the universe exerts a gravitational force on everything else; there is an interplay between magnetic fields and electrical currents.

    • What are the scientific principles that explain gravity and electromagnetism?

      • GLE 0207.12.1 Experiment with magnets to determine that objects can move without being touched.

      • GLE 0207.12.2 Realize that things fall toward the ground unless something holds them up.
