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.

2-LS1 From Molecules to Organisms: Structures and Processes

2-LS2 Ecosystems: Interactions, Energy, and Dynamics

  • 2-LS2-1 Develop and use models to compare how animals depend on their surroundings and other living things to meet their needs in the places they live.

  • 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-ESS1 Earth's Place in the Universe

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.

  • 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.

  • 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).

  • 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.

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.
