1 Physical Science

2 Life Science

3 Earth Systems Science

  • 1 Weather is a result of complex interactions of Earth's atmosphere, land and water, that are driven by energy from the sun, and can be predicted and described through complex models

    • Inquiry Questions:

      • 1 Why does weather vary from day to day?

      • 2 What are the strengths and limitations of different types of weather models?

      • 3 What are the variables that make predicting weather challenging?

      • 4 How do weather patterns relate to climate?

    • Relevance and Application:

    • Nature of Science:

      • 1 Evaluate of the accuracy of various tools used in forecasting weather.

      • 2 Use the historical context and impact of early weather research and consider the potential implications for current weather studies on science and our society.

  • 2 Earth has a variety of climates defined by average temperature, precipitation, humidity, air pressure, and wind that have changed over time in a particular location

    • Inquiry Questions:

    • Relevance and Application:

      • 1 Data tables, charts, and graphs allow people to compare and contrast various climates around the globe.

      • 2 Computer models help people understand past, present, and future climates.

    • Nature of Science:

      • 1 Ask testable questions and make a falsifiable hypothesis about earth's climate and use an inquiry based approach to find an answer.

      • 2 Describe various techniques that scientists use to study climate, and suggest ways that each technique can be used to better understand various climates and changes in climate.

  • 3 The solar system is comprised of various objects that orbit the Sun and are classified based on their characteristics

    • Inquiry Questions:

      • 1 How are the various bodies in the solar system similar and different?

      • 2 How does investigating characteristics of the various bodies in the solar system provide clues to Earth's origin and evolution?

      • 3 Why do objects such as satellites, Moons and planets stay in orbit?

      • 4 How is the life cycle of a star such as the Sun similar to the cycle of life on Earth?

    • Relevance and Application:

      • 1 Various technological methods and equipment such as telescopes are used to investigate far-away objects in the solar system and beyond.

      • 2 By representing galaxies and solar systems, planetariums allow people to simulate the experience of outer space.

    • Nature of Science:

      • 1 Understand that scientists work from the assumption that the universe is a single system in which the basic rules are the same everywhere – that planets follow the same rules about forces as other objects.

      • 2 Recognize that our current understanding of the solar system has developed over centuries of studies by many scientists, and that through continued scientific investigations and advances in data collection, we will continue to refine our understanding of the solar system.

  • 4 The relative positions and motions of Earth, Moon, and Sun can be used to explain observable effects such as seasons, eclipses, and Moon phases
