What the Oklahoma 5th grade science test covers
The blueprint reports three categories, and the questions here keep their shares. Earth and Space Sciences is the largest: why the Sun outshines other stars, patterns of shadows, the Moon and seasonal stars, Earth's four systems, where its water is, and how communities protect resources. Physical Sciences is all about matter: particles too small to see, weight that stays the same through a change, telling materials apart, and mixing substances. Life Sciences follows matter and energy through plants, animals and decomposers.
Two standards that sit where you may not expect
Gravity (5.PS2.1) is reported with Earth and Space Sciences, and the energy in food (5.PS3.1) with Life Sciences. The topics here are grouped the same way. Each answer names its standard.
This test says "weight" or "amount" where later grades say mass, and it measures matter in grams.
Questions and answers
What is the Oklahoma 5th grade state science test?
It is the Grade 5 Science test of the Oklahoma School Testing Program, OSTP. The state's science blueprints for grades 3 to 8 cover two grades, 5 and 8.
How many questions are on the Oklahoma 5th grade science test?
About 45 that count, in 15 clusters: three questions about one shared table, graph or model. About 9 more, in 3 clusters, are field-test questions that do not count. The state calls these counts approximate.
How long is the Oklahoma 5th grade science test?
It has two sections. The state estimates 45 to 55 minutes for each, and 105 to 125 minutes in all with login and directions. Its suggested maximum is 250 minutes.
Can you use a calculator on the Oklahoma 5th grade science test?
No. The specifications allow no calculators and no reference sheets on the Grade 5 Science test. Any formula or information a question needs is given in the question.
What is a passing score on the Oklahoma 5th grade science test?
There is no percent to pass. The state describes four performance levels: Advanced, Proficient, Basic and Below Basic. The percent on this page is practice and is not one of those levels.
