  • 2-PS2-3 Recognize the effect of multiple pushes and pulls on an object's movement or non-movement.

• 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

• 2-LS1 From Molecules to Organisms: Structures and Processes

  • 2-LS1-1 Use evidence and observations to explain that many animals use their body parts and senses in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water, and air.

  • 2-LS2-2 Predict what happens to animals when the environment changes (temperature, cutting down trees, wildfires, pollution, salinity, drought, land preservation).

• 2-LS3 Heredity: Inheritance and Variation of Traits

  • 2-LS3-1 Use evidence to explain that living things have physical traits inherited from parents and that variations of these traits exist in groups of similar organisms.

    • Match animals to their parents (2)
    • Match plants to their parents (2)

ESS Earth and Space Sciences

• 2-ESS1 Earth's Place in the Universe

  • 2-ESS1-1 Recognize that some of Earth's natural processes are cyclical, while others have a beginning and an end. Some events happen quickly, while others occur slowly over time.

    • Changes to Earth's surface: earthquakes (2-P.3)
    • Changes to Earth's surface: volcanic eruptions (2-P.4)
    • Changes to Earth's surface: erosion (2-P.5)

• 2-ESS2 Earth's Systems

  • 2-ESS2-1 Compare the effectiveness of multiple solutions designed to slow or prevent wind or water from changing the shape of the land.

    • Changes to Earth's surface: erosion (2-P.5)
    • Evaluate multiple design solutions to prevent flooding (3-V.2)

  • 2-ESS2-2 Observe and analyze how blowing wind and flowing water can move Earth materials (soil, rocks) from one place to another, changing the shape of a landform and affecting the habitats of living things.

    • Changes to Earth's surface: erosion (2-P.5)

  • 2-ESS2-3 Compare simple maps of different land areas to observe the shapes and kinds of land (rock, soil, sand) and water (river, stream, lake, pond).

    • Water on Earth (2-O.1)
    • Identify Earth’s land features (2-O.3)

  • 2-ESS2-4 Use information obtained from reliable sources to explain that water is found in the ocean, rivers, streams, lakes, and ponds, and may be solid or liquid.

ETS Engineering, Technology, and Applications of Science
