Idaho Grade 3 Science Online Center

Idaho tests science in grades 5, 8, and 11, not in grade 3, so third grade is the year to build the ideas ISAT Science will ask about later. Practice tests, skill quizzes, flashcards, and every Idaho science standard for this grade, free.

Idaho Grade 3 Science Topics

These are the 12 science standards Idaho sets for grade 3, from the Idaho Science Content Standards, grouped and ordered exactly the way the state's own standards document groups them. Each one is tagged with its official code so you can trace it straight back to the state document.

Idaho standard codes

PS Physical science

  • PS-1.1PS-1.3Forces, Motion, and Interactions
  • PS-1.2Observations Measurements Object'S Motion Provide Evidence Pattern Used
  • PS-1.4Magnets, Electricity, and Circuits

LS Life science

  • LS-1.1LS-2.1LS-3.1LS-3.3Organism Needs, Structures, and Life Cycles
  • LS-3.2Cells, Body Systems, and Genetics

ESS Earth and space science

  • ESS-2.1Claim About Merit Solution Reduces Impacts Weather Related

Grouped and ordered from the state's own standards document.

Idaho Grade 3 Science Standards

The full text of every grade 3 science standard in the Idaho Science Content Standards. If your Idaho classroom or report card mentions a code, you will find it here.

PS Physical science

  • PS-1.1Forces, Motion, and InteractionsPlan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object
  • PS-1.2Observations Measurements Object'S Motion Provide Evidence Pattern UsedMake observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion
  • PS-1.3Forces, Motion, and InteractionsAsk questions to determine cause and effect relationships of static electricity or magnetic interactions between two objects not in contact with each other
  • PS-1.4Magnets, Electricity, and CircuitsDefine a problem that can be solved by applying scientific ideas about magnets

LS Life science

  • LS-1.1Organism Needs, Structures, and Life CyclesDevelop models to demonstrate that living things, although they have unique and diverse life cycles, all have birth, growth, reproduction, and death in common
  • LS-2.1Organism Needs, Structures, and Life CyclesConstruct an argument that some animals form groups that help members survive
  • LS-3.1Organism Needs, Structures, and Life CyclesAnalyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms
  • LS-3.2Cells, Body Systems, and GeneticsUse evidence to support the explanation that traits can be influenced by the environment
  • LS-3.3Organism Needs, Structures, and Life CyclesConstruct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all

ESS Earth and space science

  • ESS-1.1Water Cycle, Weather, Climate, and AtmosphereRepresent data in tables and graphical displays to describe typical weather conditions expected during a particular season
  • ESS-1.2Water Cycle, Weather, Climate, and AtmosphereObtain and combine information to describe climates in different regions of the world
  • ESS-2.1Claim About Merit Solution Reduces Impacts Weather RelatedMake a claim about the merit of a design solution that reduces the impacts of a weather-related hazard

Idaho Grade 3 Science FAQ

Does Idaho test science in grade 3?

No. Idaho gives ISAT Science in grades 5, 8, and 11, so grade 3 students do not sit a state science test this year. The standards on this page are still the ones grade 3 teachers teach, and they are what the next science test builds on.

Which standards does grade 3 science in Idaho follow?

Idaho follows the Idaho Science Content Standards, published by the Idaho Department of Education. All 12 of this grade's standards are listed further down the page with their official codes.

How long are the practice tests?

Each of the six practice tests has 25 questions and a 45-minute timer. The timer auto-submits at zero and you get your score, a breakdown by science area, and a written explanation for every question.

Is any of this free?

Yes, every practice test, quiz, and flashcard set on this page is free and needs no login. Your progress is saved in your own browser and nowhere else.

What is the fastest way to use this page?

Take practice test 1 cold. Look at the topic breakdown, pick the weakest science area, and do that skill quiz. Then read the quick review for that area and come back for practice test 2.
