Actions

1 Physical Science

  • 1 Energy comes in many forms such as light, heat, sound, magnetic, chemical, and electrical

    • Inquiry Questions:

    • Relevance and Application:

      • 1 There are multiple energy sources, both renewable and nonrenewable.

      • 2 Energy can be used or stored. For example, it can be stored in a battery and then used when running a portable media player such as an iPod.

      • 3 Transportation, manufacturing, and technology are driven by energy.

    • Nature of Science:

      • 1 Ask testable questions about energy, make a falsifiable hypothesis and design an inquiry based method of finding the answer, collect data, and form a conclusion.

      • 2 Understand that models are developed to explain and predict phenomena that cannot be directly observed.

      • 3 Critically evaluate models of energy, identifying the strengths and weaknesses of the model in representing what happens in the real world.

      • 4 Create plans to decrease electrical energy use for one week and evaluate the results.

2 Life Science

3 Earth Systems Science

  • 1 Earth is part of the solar system, which includes the Sun, Moon, and other bodies that orbit the Sun in predictable patterns that lead to observable paths of objects in the sky as seen from Earth

    • Inquiry Questions:

      • 1 What are the patterns of movement for the Sun and Moon across the sky?

      • 2 How does Earth compare to other objects orbiting the Sun?

      • 3 How do we study the solar system?

    • Relevance and Application:

      • 1 Space exploration has produced data to answer questions about the solar system.

      • 2 Comets are observable objects seen from Earth which provide scientists data about the solar system.

      • 3 Orbits in a predictable pattern in space influence season's on Earth.

    • Nature of Science:

      • 1 Understand that models are developed to explain and predict natural phenomena that cannot be directly observed because they happen over long periods of time.

      • 2 Critically evaluate models of the solar system, identifying the strengths and weaknesses of the model in representing what happens in the real solar system.
