Missouri Grade 4 Science Online Center

Missouri tests science in grades 5 and 8, not in grade 4, so fourth grade is the year to build the ideas MAP Grade-Level Assessment Science will ask about later. Practice tests, skill quizzes, flashcards, and every Missouri science standard for this grade, free.

PS Physical Sciences

  • 4.PS2.A.1Forces, Motion, and InteractionsMake observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion
  • 4.PS2.A.2Forces, Motion, and InteractionsPlan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object
  • 4.PS2.B.1Forces, Motion, and InteractionsPlan and conduct a fair test to compare and contrast the forces (measured by a spring scale in Newtons) required to overcome friction when an object moves over different surfaces (i.e., rough/smooth)
  • 4.PS2.B.2Forces, Motion, and InteractionsPredict how changes in either the amount of force applied to an object or the mass of the object affects the motion (speed and direction) of the object
  • 4.PS3.A.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.B.1Magnets, Electricity, and CircuitsProvide evidence to construct an explanation of an energy transformation (e.g. Temperature change, light, sound, motion, and magnetic effects)
  • 4.PS3.B.2Energy Forms, Transfer, and TransformationApply scientific ideas to design, test, and refine a device that converts energy from one form to another
  • 4.PS3.C.1Models Simple Machines Change Amount Effort Force DirectionUse models to explain that simple machines change the amount of effort force and/or direction of force
  • 4.PS4.A.1Light, Sound, and Wave BehaviorDevelop a model of waves to describe patterns in terms of amplitude or wavelength and that waves can cause objects to move

LS Life Sciences

  • 4.LS1.A.1Organism Needs, Structures, and Life CyclesConstruct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and plant reproduction
  • 4.LS1.D.1Organism Needs, Structures, and Life CyclesUse a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways

ESS Earth and Space Sciences

  • 4.ESS1.C.1Earth Materials, Rocks, Fossils, and LandformsIdentify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time
  • 4.ESS2.A.1Earth Materials, Rocks, Fossils, and LandformsPlan and conduct scientific investigations or simulations to provide evidence how natural processes (e.g. Weathering and erosion) shape Earth's surfaces
  • 4.ESS2.B.1Data Analysis, Patterns, and Model LimitsAnalyze and interpret data from maps to describe patterns of Earth's features
  • 4.ESS3.A.1Natural Resources and Human ImpactsGenerate and compare multiple solutions to reduce the impacts of natural Earth processes on humans

ETS Engineering, Technology, and Application of Science

  • 4.ETS1.A.1Engineering Design and Solution EvaluationDefine a simple design problem reflecting a need or a want that includes specified crtieria for success and constraints on materials, time, or cost
  • 4.ETS1.B.1Engineering Design and Solution EvaluationGenerate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and contraints of the problem
  • 4.ETS1.C.1Carry Out Fair Test Which Variables Controlled FailurePlan and carry out fair test in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved

Missouri Grade 4 Science FAQ

Does Missouri test science in grade 4?

No. Missouri gives MAP Grade-Level Assessment Science in grades 5 and 8, so grade 4 students do not sit a state science test this year. Missouri also gives a high school biology test. The standards on this page are still the ones grade 4 teachers teach, and they are what the next science test builds on.

Which standards does grade 4 science in Missouri follow?

Missouri follows the Missouri Learning Standards: Science, published by the Missouri Department of Elementary and Secondary Education. All 18 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.
