IDAHOTHE GEM STATE
Idaho Grade 2 Science Online Center
No state science assessment in grade 1 or 2. The ISAT science assessment is given in grades 5, 8, and 11. Grade 2 is where the habit of looking closely gets built, so this page keeps it small and hands-on: six short practice tests, 9 skill quizzes, and every Idaho science standard for this grade, free.

Every grade 2 science standard in the Idaho Content Standards – Science. If your Idaho classroom or report card mentions a code, you will find it here with its full wording.
Physical Science
- 2-PS-1.1Describing and Sorting MaterialsPlan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
- 2-PS-1.2Choosing the Right MaterialAnalyze data obtained from testing different materials to determine which materials have the properties best suited for an intended purpose.
- 2-PS-1.3Taking Apart and RebuildingMake observations to construct an evidence-based argument that objects, when disassembled, may be used to create new objects using the same components.
- 2-PS-1.4Heating and Cooling ChangesConstruct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
Life Science
- 2-LS-1.1What Plants NeedPlan and conduct an investigation to determine the impact of light and water on the growth of plants.
- 2-LS-1.2Seeds and PollinationDevelop a model that demonstrates how plants depend on animals for pollination or the dispersal of seeds.
- 2-LS-2.1Habitats and Diversity of LifeMake observations of plants and animals to compare the diversity of life in different habitats.
Earth and Space Science
- 2-ESS-1.1Fast and Slow Earth ChangesUse information from several sources to provide evidence that Earth events can occur quickly or slowly.

Idaho Grade 2 Science FAQ
Does Idaho test science in grade 2?
No state science assessment in grade 1 or 2. The ISAT science assessment is given in grades 5, 8, and 11. The standards on this page are still what grade 2 teachers in Idaho teach, and they are what later science testing is built on.
Which standards does grade 2 science in Idaho follow?
Idaho follows the Idaho Content Standards – Science. All 11 of this grade’s standards are listed further down this page with their official codes.
How long are the practice tests?
Each of the six practice tests has 14 questions and no timer. A second grader can work through one in about ten to fifteen minutes, and there is no clock counting down while they think.
My child cannot read the questions yet. Can we still use this?
Yes, and that is how most families use it. The questions are written short and plain so you can read them aloud, and the explanation after each answer is written for you, not for the child. It says why the right answer is right and suggests something you can try together.
Is any of this free?
Yes. Every practice test and quiz on this page is free and needs no login. Progress is saved in your own browser and nowhere else.
What is the fastest way to use this page?
Do practice test 1 together, without helping. Look at the breakdown by science area, pick the weakest one, and do that skill quiz. There are 9 quizzes, one per idea, so you can work on the shaky part instead of everything at once.
