Colorado Grade 5 Science Standards

The full text of every grade 5 science standard in the Colorado Academic Standards: Science. If your Colorado classroom or report card mentions a code, you will find it here.

5.1 Physical Science

  • 5.1.1.aParticles, Atoms, Elements, and CompoundsDevelop a model to describe that matter is made of particles too small to be seen
  • 5.1.1.bScientific Tools, Measurement, and Data DisplaysMake observations and measurements to identify materials based on their properties
  • 5.1.2.aMixtures, Solutions, and Conservation of MatterMeasure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling or mixing substances, the total weight of matter is conserved
  • 5.1.2.bChemical and Physical ChangesConduct an investigation to determine whether the mixing of two or more substances results in new substances
  • 5.1.3.aGravity and Object MotionSupport an argument that the gravitational force exerted by Earth on objects is directed down
  • 5.1.4.aOrganism Needs, Structures, and Life CyclesUse models to describe that energy in animals' food (used for body repair, growth and motion and to maintain body warmth) was once energy from the sun

5.2 Life Science

  • 5.2.1.aOrganism Needs, Structures, and Life CyclesSupport an argument that plants get the materials they need for growth chiefly from air and water
  • 5.2.2.aOrganism Needs, Structures, and Life CyclesDevelop a model to describe the movement of matter among plants, animals, decomposers, and the environment

5.3 Earth and Space Science

  • 5.3.1.aSun, Moon, Earth, Stars, and Space SystemsSupport an argument that differences in the apparent brightness of the sun compared to other stars is due to their relative distances from the Earth
  • 5.3.2.aSun, Moon, Earth, Stars, and Space SystemsRepresent data in graphical displays to reveal patterns of daily changes in length and direction of shadows, day and night, and the seasonal appearance of some stars in the night sky
  • 5.3.3.aWater Cycle, Weather, Climate, and AtmosphereDevelop a model using an example to describe ways the geosphere, biosphere, hydrosphere and/or atmosphere interact
  • 5.3.4.aEarth's Water, Freshwater, and Saltwater ResourcesDescribe and graph the amounts and percentages of saltwater and freshwater in various reservoirs to provide evidence about the distribution of water on Earth
  • 5.3.5.aNatural Resources and Human ImpactsObtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment
