PS Physical Sciences

  • 2-PS2 Motion and Stability: Forces and Interactions

  • 2-PS3 Energy

    • 2-PS3-1 Demonstrate how a stronger push or pull makes things go faster and how faster speeds during a collision can cause a bigger change in the shape of the colliding objects.

    • 2-PS3-2 Make observations and conduct experiments to provide evidence that friction produces heat and reduces or increases the motion of an object.

  • 2-PS4 Waves and Their Applications in Technologies for Information Transfer

    • 2-PS4-1 Plan and conduct investigations to demonstrate the cause and effect relationship between vibrating materials (tuning forks, water, bells) and sound.

    • 2-PS4-2 Use tools and materials to design and build a device to understand that light and sound travel in waves and can send signals over a distance.

    • 2-PS4-3 Observe and demonstrate that waves move in regular patterns of motion by disturbing the surface of shallow and deep water.

LS Life Sciences

ESS Earth and Space Sciences

ETS Engineering, Technology, and Applications of Science

  • 2-ETS1 Engineering Design

    • 2-ETS1-1 Define a simple problem that can be solved through the development of a new or improved object or tool by asking questions, making observations, and gather accurate information about a situation people want to change.

    • 2-ETS1-2 Develop a simple sketch, drawing, or physical model that communicates solutions to others.

    • 2-ETS1-3 Recognize that to solve a problem, one may need to break the problem into parts, address each part, and then bring the parts back together.

    • 2-ETS1-4 Compare and contrast solutions to a design problem by using evidence to point out strengths and weaknesses of the design.

  • 2-ETS2 Links Among Engineering, Technology, Science, and Society

    • 2-ETS2-1 Use appropriate tools to make observations, record data, and refine design ideas.

    • 2-ETS2-2 Predict and explain how human life and the natural world would be different without current technologies.
