STEM.S. SCIENCE: Next Generation Science Standards (NGSS)

NGSS.4-ESS. EARTH AND SPACE SCIENCE

4-ESS2. Earth’s Systems
Students who demonstrate understanding can:
4-ESS2-1. Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.4-ESS2-2. Analyze and interpret data from maps to describe patterns of Earth’s features.
4-ESS3. Earth and Human Activity
Students who demonstrate understanding can:
4-ESS3-1. Obtain and combine information to describe that energy and fuels are derived from natural resources and their uses affect the environment.4-ESS3-2. Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans.

NGSS.4-LS. LIFE SCIENCE

4-LS1. From Molecules to Organisms: Structures and Processes
Students who demonstrate understanding can:
4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.

NGSS.4-PS. PHYSICAL SCIENCE

4-PS3. Energy
Students who demonstrate understanding can:
4-PS3-1. Use evidence to construct an explanation relating the speed of an object to the energy of that object.4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
4-PS4. Waves and their Applications in Technologies for Information Transfer
Students who demonstrate understanding can:
4-PS4-1. Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.
