Arizona Grade 3 Science Online Center

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

Arizona Grade 3 Science FAQ

Does Arizona test science in grade 3?

No. Arizona gives the AzSCI 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 Arizona follow?

Arizona follows the Arizona Science Standards, published by the Arizona Department of Education. All 8 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.
