PS Physical Sciences
- 4-PS4-2Light Reflecting Objects Entering Eye Allows Objects SeenDevelop a model to describe that light reflecting from objects and entering the eye allows objects to be seen
- 4-PS4-1Light, Sound, and Wave BehaviorDevelop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move

- 4-PS3-1Evidence Explanation Relating Speed Object Energy Object SpeedUse evidence to construct an explanation relating the speed of an object to the energy of that object
- 4-PS3-2Magnets, Electricity, and CircuitsMake observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents
- 4-PS3-3Questions Outcomes About Changes Energy Occur When ObjectsAsk questions and predict outcomes about the changes in energy that occur when objects collide
- 4-PS3-4Energy Forms, Transfer, and TransformationApply scientific ideas to design, test, and refine a device that converts energy from one form to another

Arkansas Grade 4 Science FAQ
Does Arkansas test science in grade 4?
Yes. Arkansas students take ATLAS Science in grade 4. ATLAS replaced ACT Aspire statewide in 2024. Arkansas tests science annually in grades 3 to 8, so grade 4 receives a science assessment.
Which standards does grade 4 science in Arkansas follow?
Arkansas follows the Arkansas Science Standards and Courses, published by the Arkansas Division of Elementary and Secondary Education. All 17 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 30 questions and a 55-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.
