PS Physical Sciences

2.PS2 Motion and Stability: Forces and Interactions
- 2.PS2.1 Analyze the push or the pull that occurs when objects collide or are connected.
  - Identify pushes and pulls (2-G.1)
- 2.PS2.2 Plan and carry out an investigation to demonstrate how pushing and/or pulling an object affects the motion of the object within a system.
  - Investigate pushes and pulls (2)
  - How do mass and force affect motion? (2-G.2)
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.
  - How do mass and force affect motion? (2-G.2)
- 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 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 Obtain information to describe how devices communicate over a distance using light or sound.
  - How do we use light and sound to communicate? (2)

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.LS1.2 Obtain and communicate information to classify animals based on their physical characteristics.
  - Identify mammals, birds, fish, reptiles, and amphibians (2-I.3)
  - Identify animals with and without backbones (2-I.4)
- 2.LS1.3 Identify ways in which some animals, both parents and offspring, participate in behaviors that help the offspring survive.
  - Benefits of group behavior: North American caribou (2-M.15)
  - Benefits of group behavior: African wild dogs (2-M.16)
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).

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.
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-R.5)
  - Evaluate multiple design solutions to prevent erosion (2-S.1)
- 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-R.5)
  - Evaluate multiple design solutions to prevent erosion (2-S.1)
- 2.ESS2.3 Develop and 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-Q.2)
  - Identify Earth’s land features (2-Q.4)
- 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.
  - Bodies of water (2-Q.1)
  - Water on Earth (2-Q.2)

ETS Engineering, Technology, and Applications of Science

2.ETS1 Engineering Design
- 2.ETS1.1 Apply an engineering design approach to identify and solve practical problems.
  - Evaluate multiple design solutions to prevent erosion (2-S.1)
- 2.ETS1.2 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.
  - Evaluate multiple design solutions to prevent erosion (2-S.1)
- 2.ETS1.3 Compare and contrast solutions to a design problem by using evidence to point out strengths and weaknesses of the design.
  - Evaluate multiple design solutions to prevent erosion (2-S.1)
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.
