1A student places 10 grams of white sugar into a glass containing 100 grams of warm water and stirs until the sugar crystals disappear. The liquid remains completely clear. The student then measures the total mass of the glass and liquid. Which statement best describes the properties of the sugar in this phenomenon?
2Students tested four solid metal objects using a bar magnet to classify them by their physical properties. They recorded their observations in the table below: [Data Table: Magnetic Testing] - Object 1 (Iron Nail): Attracted to magnet - Object 2 (Aluminum Foil): Not attracted - Object 3 (Copper Wire): Not attracted - Object 4 (Steel Paperclip): Attracted to magnet Based on these observations, which conclusion is supported by the evidence?
3A student drops a wooden block and a solid iron cube of identical volume into a tub of fresh water. The wooden block floats at the surface, while the iron cube sinks to the bottom. What physical property explains why the wooden block floats while the iron cube sinks?
4During an electrical conductivity investigation, a student connects four test materials into a simple circuit with a 1.5V battery and a light bulb. The results are shown below: [Data Table: Electrical Circuit Testing] - Material A (Copper Strip): Light bulb shines brightly - Material B (Plastic Straw): Light bulb does not light - Material C (Salt Water Solution): Light bulb shines brightly - Material D (Dry Wooden Stick): Light bulb does not light Which statement correctly classifies these materials based on their physical properties?
5A teacher places three spoons made of different materials—metal, wood, and plastic—into a bowl of hot soup (85°C). Small dots of butter are stuck to the top handle of each spoon outside the bowl. After 3 minutes, the butter on the metal spoon melts completely, while the butter on the wooden and plastic spoons remains solid. What does this investigation demonstrate about thermal conductivity?
6A science class measures the mass and volume of four unknown solid samples to determine their physical properties. They record the data in the table below: [Data Table: Mass and Volume Measurements] - Sample 1: Mass = 27.0 g, Volume = 10.0 cm³ - Sample 2: Mass = 78.0 g, Volume = 10.0 cm³ - Sample 3: Mass = 11.3 g, Volume = 1.0 cm³ - Sample 4: Mass = 27.0 g, Volume = 3.0 cm³ Given that pure aluminum has a density of 2.7 g/cm³ (Density = Mass ÷ Volume), which sample is most likely made of pure aluminum?
7A student pumps air into an empty, deflated basketball until it becomes firm and round. The student measures the mass of the ball before and after pumping air into it, as shown below: [Scenario Data] - Mass of deflated ball: 570 grams - Mass of fully inflated ball: 584 grams Which statement is best supported by this phenomenon?
8A lab technician investigates four clear liquids to determine their physical properties. The data collected is presented in the table below: [Data Table: Properties of Clear Liquids] - Liquid W: Boiling Point = 100°C, Density = 1.00 g/mL, Freezing Point = 0°C - Liquid X: Boiling Point = 78°C, Density = 0.79 g/mL, Freezing Point = -114°C - Liquid Y: Boiling Point = 100°C, Density = 1.00 g/mL, Freezing Point = 0°C - Liquid Z: Boiling Point = 290°C, Density = 1.26 g/mL, Freezing Point = 18°C Based on these physical properties, which two samples are most likely the exact same substance?
9A student is given a dry mixture containing iron filings, table salt, and coarse sand. The student needs to separate all three components using their physical properties. [Proposed Separation Procedure] Step 1: Pass a strong magnet over the mixture. Step 2: Add water to the remaining mixture and stir thoroughly. Step 3: Filter the mixture through filter paper. Step 4: Evaporate the liquid collected from the filter. Which statement correctly evaluates this plan?
10A student pours 20 mL of vinegar into a zipper plastic bag and places a small scoop of baking soda into the corner before sealing the bag tightly. When the student tilts the bag to mix the powders, bubbles vigorously form, the bag inflates like a balloon, and the bottom feels cold to the touch. What evidence indicates that a chemical change occurred?
About the OSTP Science Grade 5 Exam
The OSTP Grade 5 Science assessment measures proficiency against the Oklahoma Academic Standards for Science using a three-dimensional, phenomenon-based cluster format. Two physical science standards are deliberately reported outside Physical Sciences: 5.PS3.1 is reported in Life Sciences and 5.PS2.1 in Earth and Space Sciences, reflecting how they are usually taught.
Assessment
Online cluster-based test delivered in two sections. Each of the 15 operational clusters aligns to one Oklahoma Academic Standard with its Disciplinary Core Idea(s), Science and Engineering Practice and Crosscutting Concept. Blueprint: Earth and Space Sciences 33-40%, Physical Sciences 27-33%, Life Sciences 27-33%.
Time Limit
Approximately 125 minutes across two sections of 45-55 minutes each (suggested maximum 250 minutes); not strictly timed
Passing Score
No pass/fail mark. Reported on the Oklahoma Performance Index (OPI) 200–399 scale, where 300 is always Proficient, in four performance levels: Below Basic, Basic, Proficient, Advanced.
Exam Fee
No fee to students (Oklahoma State Department of Education (OSDE); delivered under contract by Cognia)
OSTP Science Grade 5 Exam Content Outline
Earth and Space Sciences
Apparent brightness of stars, patterns of shadows and sky objects, interactions of the geosphere, biosphere, hydrosphere and atmosphere, distribution of Earth's water, protecting Earth's resources, and gravity as a downward force (5.ESS1-5.ESS3, 5.PS2.1a).
Physical Sciences
Matter made of particles too small to see, conservation of matter when heating, cooling or mixing, identifying materials by their properties, and investigating whether mixing substances forms new substances (5.PS1.1-5.PS1.4).
Life Sciences
Plants obtaining materials for growth from air and water, movement of matter among plants, animals, decomposers and the environment, factors that upset ecosystem stability, and energy in food tracing back to the sun (5.LS1-5.LS2, 5.PS3.1a).

Frequently Asked Questions
How many questions are on the official OSTP Grade 5 Science test?
The operational test contains 15 clusters. Each cluster has three items — either three multiple-choice items, or two multiple-choice items plus a technology-enhanced item — so about 45 operational items in total.
What is a science cluster?
A cluster is a set of items linked to one common stimulus, usually a real-world phenomenon. Each cluster aligns to a single Oklahoma Academic Standard with its Disciplinary Core Idea, Science and Engineering Practice and Crosscutting Concept.
Why do some physical science standards appear under other categories?
The blueprint states that 5.PS3.1 is reported in Life Sciences and 5.PS2.1 in Earth and Space Sciences, because that is how those standards are typically incorporated into classroom units.
Is there a passing score?
No. Results are reported on the Oklahoma Performance Index scale of 200–399, where 300 is always Proficient, and in four performance levels: Below Basic, Basic, Proficient and Advanced.
Is the Grade 5 Science test available in Spanish?
Yes. Cognia offers Spanish online forms for Grades 5 and 8 Science, along with Spanish text-to-speech; students must be scheduled for the Spanish test.
