Sample ISAT Science Grade 5 Practice Questions

Try these sample questions to test your ISAT Science Grade 5 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 101+ question experience with AI tutoring.

1Most of Earth's water is found in oceans. About what fraction of Earth's water is salt water?
A.About one-fourth
B.About one-half
C.About three-fourths
D.Almost all of it
Explanation: Nearly all of Earth's water is salt water in the oceans. Fresh water in lakes, rivers, ice, and underground is only a small fraction of the total.
2Why does the Sun look much brighter than other stars in the night sky?
A.The Sun is the only star that produces light
B.The Sun is much closer to Earth than other stars
C.Other stars are always behind the Moon
D.The Sun is made of different materials that glow more
Explanation: The Sun is a star, just like many stars we see at night. It appears much brighter mainly because it is far closer to Earth than those distant stars.
3A class in Boise records that the Sun appears in the east each morning and sets in the west each evening, and that the pattern of daylight and darkness repeats about every 24 hours. What causes this daily pattern?
A.Earth rotates once on its axis about every 24 hours
B.Earth moves closer to and farther from the Sun each day
C.The Moon blocks the Sun every night
D.Clouds cover the Sun every evening
Explanation: Earth spins once on its axis about every 24 hours. The side turned toward the Sun has daylight and the side turned away is in darkness, and that same spin makes the Sun appear to move from east to west across the sky.
4A student stands outside at noon and again late afternoon. Why is the student's shadow longer in the late afternoon?
A.The Sun is lower in the sky, so sunlight strikes the student at a lower angle
B.The student grows taller during the day
C.Earth moves farther from the Sun each afternoon
D.Shadows always get longer as temperature drops
Explanation: As the Sun appears lower toward the horizon, sunlight strikes objects at a lower angle and casts longer shadows. At noon the Sun is higher, so shadows are shorter.
5Which statement best describes weather?
A.The average conditions of a place over many years
B.The day-to-day conditions of the atmosphere at a place
C.Only the temperature of a place
D.The number of mountains near a place
Explanation: Weather is what the atmosphere is like day to day—temperature, rain, wind, clouds, and so on. Climate is the long-term average pattern of those conditions.
6Fossils of ocean animals are found in rock layers high in mountains. What is the best explanation?
A.Ocean animals once climbed the mountains and died there
B.Those rock layers formed in an ancient ocean and were later lifted up
C.People carried the fossils up and buried them
D.Rain turns mountain rocks into ocean fossils
Explanation: Fossils form where organisms lived and were buried. Ocean animal fossils in mountain rocks show those layers formed under ancient seas, then Earth's forces lifted them upward over long time.
7Which process breaks large rocks into smaller pieces without moving them to a new place?
A.Erosion
B.Weathering
C.Condensation
D.Photosynthesis
Explanation: Weathering breaks rocks into smaller pieces. Erosion is the process that moves those pieces to new places by water, wind, ice, or gravity.
8Coal, oil, and natural gas are often called fossil fuels. Why?
A.They form quickly from living plants each year
B.They form over millions of years from remains of ancient organisms
C.They are rocks mined only from volcanoes
D.They are pure water stored underground
Explanation: Fossil fuels form when remains of ancient plants and animals are buried and changed by heat and pressure over millions of years. They are nonrenewable on human timescales.
9Which human action best helps protect fresh water resources?
A.Pouring unused paint into a storm drain
B.Using less water and preventing pollution from entering rivers and aquifers
C.Dumping trash along riverbanks to keep streets clean
D.Removing all plants from the edges of streams
Explanation: Protecting fresh water means using water wisely and keeping pollutants out of rivers, lakes, and groundwater. Plants along streams also help filter runoff.
10Which Earth system includes all living things?
A.Atmosphere
B.Hydrosphere
C.Geosphere
D.Biosphere
Explanation: The biosphere is the part of Earth made of living organisms. The atmosphere is air, the hydrosphere is water, and the geosphere is rock and land.

About the ISAT Science Grade 5 Exam

The Idaho Standards Achievement Test (ISAT) Science — Grade 5 is Idaho's statewide summative science assessment for grade 5. It measures three-dimensional Idaho State Science Standards (ISSS) across Earth and Space Science, Life Science, and Physical Science using phenomena-based item clusters and stand-alone items. Official forms are computer-based on the Idaho Portal. The elementary blueprint samples grade 3–5 Idaho State Science Standards. OpenExamPrep free practice is an English-language four-option MCQ study aid aligned to ISAT Science domains—not official secure content, not a full simulation of multi-part clusters, and not a substitute for classroom three-dimensional science learning. Official ISAT Science administration is available in English and in Spanish: the SDE ISAT program page states that Spanish-speaking students may take the math and science tests in Spanish or receive Spanish text-to-speech, and the Idaho UAAG lists Spanish dual-language supports for science. This practice bank is English-only.

ISAT Science Grade 5 Study Tips from Top Performers

1Practice explaining a short phenomenon with evidence before choosing an answer—ISAT Science clusters start from real-world observations.
2Connect core ideas to a science practice (model, analyze data, construct an argument) and a crosscutting concept (cause and effect, systems, energy and matter).
3Rotate study across Earth and Space, Life, and Physical Science so no domain is neglected—blueprints balance domain coverage.
4Use Idaho Portal practice/sample science tests to learn the delivery tools and cluster navigation; use this bank for domain knowledge and reasoning.
5For design or hazard items, identify criteria, constraints, and tradeoffs instead of guessing a single 'best invention.'
6Review grade-band vocabulary from the Idaho Science Content Standards rather than memorizing trivia disconnected from standards.

Frequently Asked Questions

What is the ISAT Science Grade 5 assessment?

It is Idaho's statewide summative science assessment for grade 5, administered by the Idaho State Department of Education and delivered through the Idaho Portal (Cambium Assessment). It aligns to three-dimensional Idaho State Science Standards across Earth and Space Science, Life Science, and Physical Science.

Who takes ISAT Science?

All Idaho public school students in grades 5, 8, and 11 take ISAT Science unless they qualify for the Idaho Alternate Assessment (IDAA) in science. Off-grade summative science testing is not permitted.

How many questions are on ISAT Science?

Elementary ISAT Science summative blueprint: 18 operational items (6 clusters + 12 stand-alones) balanced as 6 Earth/Space, 6 Life, and 6 Physical Science items, plus field-test items that do not count toward the score. Total delivered length is about 19–22 items depending on field-test assignment. Official items are not all four-option multiple choice.

How long is ISAT Science?

Estimated about 88 minutes total for elementary science (about 9 minutes per cluster, 2 minutes per stand-alone, plus ~10 minutes for field-test items) per SDE Science ISAT FAQ timing table. Schools schedule within the statewide spring summative window; treat as planned school session time rather than a hard student stopwatch limit.

What score is proficient?

Students scoring Level 3 (Proficient) or Level 4 (Advanced) are considered proficient. Exact scale cut scores by grade are published on the Idaho Portal as ISAT Cut Scores.

Is there a student fee?

No direct student registration fee. ISAT Science is part of Idaho's school-administered statewide assessment program.

Are these official ISAT items?

No. These are original English multiple-choice study questions aligned to ISAT Science domains and Idaho science standards. They do not copy secure operational items and are not a full simulation of phenomena-based clusters.

Is ISAT Science the same as Smarter Balanced?

No. ISAT English Language Arts and Mathematics use the Smarter Balanced assessment system. ISAT Science is a separate Idaho science assessment aligned to the Idaho State Science Standards.
