1-4 Scientific and engineering practices

  • 1 The student asks questions, identifies problems, and plans and safely conducts classroom, laboratory, and field investigations to answer questions, explain phenomena, or design solutions using appropriate tools and models. The student is expected to:

  • 2 The student analyzes and interprets data to derive meaning, identify features and patterns, and discover relationships or correlations to develop evidence-based arguments or evaluate designs. The student is expected to:

  • 3 The student develops evidence-based explanations and communicates findings, conclusions, and proposed solutions. The student is expected to:

    • A develop explanations and propose solutions supported by data and models;

    • B communicate explanations and solutions individually and collaboratively in a variety of settings and formats; and

    • C listen actively to others' explanations to identify important evidence and engage respectfully in scientific discussion.

  • 4 The student knows the contributions of scientists and recognizes the importance of scientific research and innovation for society. The student is expected to:

    • A explain how science or an innovation can help others; and

    • B identify scientists and engineers such as Alexander Graham Bell, Marie Daly, Mario Molina, and Jane Goodall and explore what different scientists and engineers do.

5 Recurring themes and concepts

6 Matter and its properties

7-8 Force, motion, and energy

  • 7 The student knows that forces cause changes in motion and position in everyday life. The student is expected to:

  • 8 The student knows that energy is everywhere and can be observed in everyday life. The student is expected to:

    • A demonstrate and explain that sound is made by vibrating matter and that vibrations can be caused by a variety of means, including sound;

    • B explain how different levels of sound are used in everyday life such as a whisper in a classroom or a fire alarm; and

    • C design and build a device using tools and materials that use sound to solve the problem of communicating over a distance.

9-11 Earth and space

  • 9 The student knows that there are recognizable patterns in the natural world and among objects in the sky. The student is expected to:

    • A describe the Sun as a star that provides light and heat and explain that the Moon reflects the Sun's light; and

    • B observe objects in the sky using tools such as a telescope and compare how objects in the sky are more visible and can appear different with a tool than with an unaided eye.

  • 10 The student knows that the natural world includes earth materials that can be observed in systems and processes. The student is expected to:

  • 11 The student knows that earth materials and products made from these materials are important to everyday life. The student is expected to:

    • A distinguish between natural and manmade resources; and

    • B describe how human impact can be limited by making choices to conserve and properly dispose of materials such as reducing use of, reusing , or recycling paper, plastic, and metal.
