Iowa Grade 5 Science Standards
The full text of every grade 5 science standard in the Iowa Academic Standards: Science. If your Iowa classroom or report card mentions a code, you will find it here.
PS Physical Science
- 5-PS1-1Particles, Atoms, Elements, and CompoundsDevelop a model to describe that matter is made of particles too small to be seen
- 5-PS1-2Mixtures, 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-PS1-3Material Properties and UsesMake observations and measurements to identify materials based on their properties
- 5-PS1-4Chemical and Physical ChangesConduct an investigation to determine whether the mixing of two or more substances results in new substances
- 5-PS2-1Forces, Motion, and InteractionsSupport an argument that the gravitational force exerted by Earth on objects is directed down
- 5-PS3-1Energy in Food and Living SystemsUse models to describe that energy in animals' food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun
LS Life Science
- 5-LS1-1Organism Needs, Structures, and Life CyclesSupport an argument that plants get the materials they need for growth chiefly from air and water
- 5-LS2-1Organism Needs, Structures, and Life CyclesDevelop a model to describe the movement of matter among plants, animals, decomposers, and the environment
ESS Earth and Space Science
- 5-ESS1-1Sun, Moon, Earth, Stars, and Space SystemsSupport an argument that the apparent brightness of the sun and stars is due to their relative distances from the Earth
- 5-ESS1-2Sun, 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-ESS2-1Water Cycle, Weather, Climate, and AtmosphereDevelop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact
- 5-ESS2-2Earth's Water, Freshwater, and Saltwater ResourcesDescribe and graph the amounts of saltwater and fresh water in various reservoirs to provide evidence about the distribution of water on Earth
- 5-ESS3-1Natural Resources and Human ImpactsObtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment
ETS Engineering, Technology & Society
- 5-ETS1-1Engineering Design and Solution EvaluationDefine a simple design problem, reflecting a need or a want, that includes specified criteria for success and constraints on materials, time, or cost
- 5-ETS1-2Engineering Design and Solution EvaluationGenerate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem
- 5-ETS1-3Carry Out Fair Tests Which Variables Controlled FailurePlan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved
