Missouri Grade 3: Math and English Too
Science is one of three Missouri grade 3 centers. Same format, same standards-first approach, for the other two subjects.

Open the English center →Missouri Grade 3 Science FAQ
Does Missouri test science in grade 3?
No. Missouri gives MAP Grade-Level Assessment Science in grades 5 and 8, so grade 3 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 3 teachers teach, and they are what the next science test builds on.
Which standards does grade 3 science in Missouri follow?
Missouri follows the Missouri Learning Standards: Science, published by the Missouri Department of Elementary and Secondary Education. All 14 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.

Missouri Grade 3 Science: study questions
How should I choose a Grade 3 science study target?
Start with the course or standards reference for this state. Explain one idea before doing its related practice, then use the feedback to decide what needs another example.
Official source ↗Are these activities official state assessments?
These are independently published learning resources. A practice score does not predict or replace an official state score. Use the directions in each activity and consult your school for official testing and accommodation rules.
