Sample SD Science Grade 5 Practice Questions

Try these sample questions to test your SD Science Grade 5 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which model BEST describes what all matter, including solids, liquids, and gases, is made of?
A.Particles that are too small to be seen without special magnification
B.Solid blocks that expand when heated and disappear when cooled
C.Continuous liquid sheets that stretch into different shapes
D.Tiny visible dust specks floating in air and water
Explanation: All matter is made of tiny particles (atoms or molecules) that are far too small to be seen with the naked eye. These particles are in constant motion and determine the properties and states of matter. Observing macro-level properties provides evidence for this particle model.
2A student pumps air into a deflated basketball until it feels firm. How does this provide evidence that air is matter?
A.The ball becomes heavier and takes up more space as air particles fill it
B.The ball becomes lighter because air has negative weight
C.The leather shell of the ball changes into a new chemical substance
D.The air inside the ball disappears and turns into energy
Explanation: Matter is anything that has mass and takes up volume. Adding air increases the mass of the basketball and inflates its volume, demonstrating that air is made of particles of matter.
3A student freezes 100 grams of liquid water in a sealed container. What will the total mass of the ice be after freezing?
A.100 grams
B.50 grams
C.120 grams
D.0 grams
Explanation: According to the law of conservation of mass, matter is neither created nor destroyed during state changes. Freezing liquid water into ice changes its state and volume, but the total mass remains exactly 100 grams.
4Which tool should a student use to measure the mass of a wooden block accurately?
A.A balance scale or electronic mass scale
B.A graduated cylinder filled with water
C.A metric ruler or tape measure
D.A digital thermometer
Explanation: A balance or electronic scale measures mass in grams or kilograms. Graduated cylinders measure volume, rulers measure distance/length, and thermometers measure temperature.
5In what direction does Earth's gravitational force always pull objects near Earth's surface?
A.Down toward the center of Earth
B.North toward the geographic North Pole
C.East toward the rising Sun
D.Up toward the upper atmosphere
Explanation: Earth's gravitational force attracts all objects toward Earth's center. No matter where a person stands on Earth, 'down' points directly toward the center of the planet.
6Where does the energy stored in food originally come from?
A.Sunlight absorbed by plants during photosynthesis
B.Nutrients created deep inside Earth's core
C.Oxygen gas absorbed directly from water
D.Artificial heat generated by soil bacteria
Explanation: The primary energy source for almost all life on Earth is the Sun. Plants capture light energy from the Sun and convert it into chemical energy (sugars), which is then passed to animals through food.
7A student stirs spoonfuls of sugar into warm water until it dissolves completely. What type of change has occurred?
A.A physical change because the sugar can be recovered by evaporating the water
B.A chemical change because the sugar turns into liquid water permanently
C.A nuclear change because new atoms are created in the solution
D.No change at all because sugar disappears from existence
Explanation: Dissolving sugar is a physical change because no new chemical substance is formed. The sugar particles disperse between water molecules and can be recovered in solid form by evaporating the water.
8Which property is characteristic of all gases?
A.They expand to fill the container they are placed in
B.They maintain a fixed shape regardless of container shape
C.They cannot be compressed into a smaller volume
D.They are always heavier than liquids
Explanation: Gases have neither a fixed shape nor a fixed volume. Gas particles move freely and spread apart until they completely fill whatever container holds them.
9An ice cube weighing 25 grams melts inside a tightly closed glass jar. What is the weight of the water inside the jar after melting?
A.25 grams
B.20 grams
C.30 grams
D.0 grams
Explanation: In a closed system, melting is a physical state change that conserves total mass. The 25 grams of solid ice yields exactly 25 grams of liquid water.
10Why does an apple fall straight down when dropped anywhere on Earth?
A.Earth's gravitational force pulls objects toward Earth's center
B.Air currents always push objects toward the ground
C.Earth's rotation creates a magnetic field pushing objects down
D.The Sun pulls objects toward the horizon during the day
Explanation: Gravity is an attractive force between Earth and all objects near it, pulling them directly toward Earth's center. This downward pull causes dropped objects like apples to fall toward the ground everywhere on Earth.

About the SD Science Grade 5 Exam

The South Dakota Science Assessment for Grade 5 is the state's annual summative science assessment measuring 5th-grade students' mastery of South Dakota Science Standards. Built around three-dimensional learning (Disciplinary Core Ideas, Science and Engineering Practices, Crosscutting Concepts), the assessment evaluates matter properties, conservation of mass, gravity, food energy, plant requirements, ecosystem food webs, stellar brightness & distance, Earth rotation/orbit phenomena (shadows, day/night, constellations), and Earth system interactions (spheres). Please note: This 100-question practice bank is an English-language multiple-choice question (MCQ) study adaptation created by OpenExamPrep to help 5th-grade students practice core science standards in an accessible study format.

Assessment

One non-segmented online session. Each student receives 2 clusters and 4 stand-alone items per science discipline, presented in random order, plus either one field-test cluster or four field-test items.

Time Limit

Untimed. SD DOE reported an 85th-percentile testing time of about 107 minutes for grade 5 in spring 2025.

Passing Score

No pass/fail score. Grade 5 scale scores run 400-600: Level 1 (400-476), Level 2 (477-507), Level 3 (508-526, proficient), Level 4 (527-600).

SD Science Grade 5 Study Tips from Top Performers

1Master the particle model of matter to explain how matter is made of particles too small to be seen.
2Understand conservation of mass by remembering that total weight remains unchanged during state changes, dissolving, and mixing.
3Study ecosystem food webs to trace how energy originates from the Sun and moves through producers, consumers, and decomposers.
4Learn plant biology fundamentals: plants get the materials they need for growth chiefly from air and water, utilizing sunlight energy.
5Analyze Earth phenomena related to rotation and orbit, such as daily shadow length patterns, day/night cycles, and seasonal constellation changes.
6Understand how Earth's four major spheres (geosphere, hydrosphere, atmosphere, biosphere) interact and influence one another.
