4-PS3 Energy

  • 4-PS3-1 Use evidence to explain the cause and effect relationship between the speed of an object and the energy of an object.

  • 4-PS3-2 Observe and explain the relationship between potential energy and kinetic energy.

  • 4-PS3-3 Describe how stored energy can be converted into another form for practical use.

4-PS4 Waves and their Application in Technologies for Information Transfer

  • 4-PS4-1 Use a model of a simple wave to explain regular patterns of amplitude, wavelength, and direction.

  • 4-PS4-2 Describe how the colors of available light sources and the bending of light waves determine what we see.

  • 4-PS4-3 Investigate how lenses and digital devices like computers or cell phones use waves to enhance human senses.

4-LS2 Ecosystems: Interactions, Energy, and Dynamics

4-LS4 Biological Change: Unity and Diversity

4-ESS1 Earth's Place in the Universe

  • 4-ESS1-1 Generate and support a claim with evidence that over long periods of time, erosion (weathering and transportation) and deposition have changed landscapes and created new landforms.

  • 4-ESS1-2 Use a model to explain how the orbit of the Earth and sun cause observable patterns:

    • 4-ESS1-2-a day and night;

    • 4-ESS1-2-b changes in length and direction of shadows over a day.

4-ESS2 Earth's Systems

  • 4-ESS2-1 Collect and analyze data from observations to provide evidence that rocks, soils, and sediments are broken into smaller pieces through mechanical weathering (frost wedging, abrasion, tree root wedging) and are transported by water, ice, wind, gravity, and vegetation.

  • 4-ESS2-2 Interpret maps to determine that the location of mountain ranges, deep ocean trenches, volcanoes, and earthquakes occur in patterns.

  • 4-ESS2-3 Provide examples to support the claim that organisms affect the physical characteristics of their regions.

  • 4-ESS2-4 Analyze and interpret data on the four layers of the Earth, including thickness, composition, and physical states of these layers.

4-ESS3 Earth and Human Activity

  • 4-ESS3-1 Obtain and combine information to describe that energy and fuels are derived from natural resources and that some energy and fuel sources are renewable (sunlight, wind, water) and some are not (fossil fuels, minerals).

  • 4-ESS3-2 Create an argument, using evidence from research, that human activity (farming, mining, building) can affect the land and ocean in positive and/or negative ways.
