Sample ISASP Science Grade 5 Practice Questions

Try these sample questions to test your ISASP 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.

1An Iowa prairie food chain is: big bluestem grass → grasshopper → meadowlark → fox. What is the role of the big bluestem grass?
A.Producer that makes its own food using sunlight
B.Consumer that eats other animals
C.Decomposer that breaks down dead material only
D.Predator that hunts grasshoppers
Explanation: Producers such as grasses make their own food using sunlight (photosynthesis). Consumers eat other organisms; the grass is the starting producer in this chain.
2Why do green plants need sunlight to grow well?
A.Sunlight warms the leaves, and that warmth is the plant's food
B.Sunlight provides energy plants use to make food
C.Sunlight turns soil into plant food
D.Plants need sunlight only for color, not for energy
Explanation: Plants use light energy to make food from carbon dioxide and water. Soil minerals help, but sunlight supplies the energy for photosynthesis.
3A rabbit has brown fur like its parents. What is the best elementary explanation?
A.The rabbit chose brown fur after birth
B.Weather painted the fur brown
C.Many traits are inherited from parents
D.All rabbits must have identical fur forever
Explanation: Offspring often resemble parents because traits such as fur color can be inherited. Environment can affect some traits, but parent–offspring similarity points to heredity.
4Fossils of sea shells are found in rock layers in a place that is dry land today. What does this most strongly suggest?
A.Shells formed from rain recently
B.Fossils only form on dry land
C.Shells always travel from oceans each year
D.That area was covered by water in the past
Explanation: Marine fossils in current dry land are evidence that the area was once underwater. Rock layers can preserve organisms from past environments.
5In a pond ecosystem, frogs eat insects and herons eat frogs. If a drought kills many insects, what is a likely short-term effect?
A.Frog numbers may decrease because their food supply drops
B.Heron numbers may rise because frogs become easier to catch
C.Insect numbers will rise because frogs disappear instantly
D.The pond will stop needing any producers
Explanation: Fewer insects mean less food for frogs, so frog populations may decline. Changes at one level of a food web can affect other levels.
6Which structure–function pair is best matched for animals?
A.Bird wings: dig deep underground tunnels only
B.Fish gills: take in oxygen from water
C.Deer antlers: filter oxygen out of the air
D.Frog sticky tongue: store water for months
Explanation: Gills are structures that help many aquatic animals obtain oxygen from water. Structure and function are linked in living things.
7Where does most of a growing plant’s added mass come from?
A.Only minerals absorbed from soil
B.Sugar the roots pull directly out of the soil
C.Air and water used to build plant matter during photosynthesis
D.Electricity in the ground
Explanation: Plants build mass mainly from carbon dioxide (from air) and water using light energy. Soil minerals are needed in small amounts but are not the main source of mass.
8Which organism is a decomposer in a forest ecosystem?
A.Oak tree making food with sunlight
B.Deer eating leaves
C.Hawk hunting rabbits
D.Fungi breaking down a fallen log
Explanation: Decomposers break down dead organisms and return materials to the environment. Many fungi and bacteria are decomposers.
9A young duckling follows its mother soon after hatching. How does this behavior help survival?
A.It helps the duckling stay near protection and food sources
B.It turns the duckling into a plant
C.It stops the duckling from ever learning
D.It makes predators unable to see any ducks
Explanation: Following a parent keeps young animals near care, protection, and food. Behaviors can help survival just as structures can.
10Two siblings have the same parents but different freckle patterns. What does this best illustrate?
A.Traits never come from parents
B.Offspring of the same parents can show variation in traits
C.Siblings must be identical in every trait
D.Freckles form only from eating freckled food
Explanation: Even siblings can differ because offspring inherit combinations of traits and show variation. Variation is normal within a species.

About the ISASP Science Grade 5 Exam

The Iowa Statewide Assessment of Student Progress (ISASP) Science — Grade 5 is Iowa's statewide summative science assessment developed by Iowa Testing Programs. Science is assessed statewide in grades 5, 8, and high school (grade 11 beginning 2026–27). Items are phenomena-based and aligned to three-dimensional Iowa science standards across Life, Physical, and Earth/Space domains. OpenExamPrep offers free English multiple-choice practice aligned to those domains as a study aid—not official items or a substitute for investigations, modeling, constructed responses, or the official assessment.

Questions

32 scored questions

Time Limit

Untimed. District communications commonly schedule about 60–75 minutes for science sessions; official specifications describe ISASP as untimed with recommended administration times for planning.

Passing Score

Science continues prior reporting through spring 2026 administrations; ISASP will report four performance levels (Below, Approaching, Meeting, Exceeding) for Science after the spring 2027 administration (ITP/Pearson bulletin, Changes with ISASP Reporting for 2026).

Exam Fee

Free to students and families; ISASP is Iowa's state-funded statewide summative assessment administered through public schools and ESA-funded nonpublic schools. (Iowa Department of Education; Iowa Testing Programs (University of Iowa); delivered via Iowa Testing Programs (University of Iowa) with Pearson (TestNav / PearsonAccessnext))

ISASP Science Grade 5 Exam Content Outline

about 25–45%

Life Science

Molecules and organisms, ecosystems, heredity, and biological evolution (Iowa Core science domains).

about 25–45%

Physical Science

Matter and its interactions, motion and stability, energy, and waves.

about 25–45%

Earth and Space Sciences

Earth's place in the universe, Earth's systems, and Earth and human activity.

ISASP Science Grade 5 Study Tips from Top Performers

1Study phenomena with all three dimensions: disciplinary core ideas, science and engineering practices, and crosscutting concepts.
2Use official ISASP science practice tests on the ISASP Portal to learn item clusters and tools.
3Balance Life, Physical, and Earth/Space practice roughly evenly (each domain is targeted ~25–45%).
4Explain claims with evidence and reasoning rather than memorizing isolated facts.
5Review graphs, models, and data tables—many items require interpretation, not recall alone.
6Build stamina with untimed multi-item science clusters.

Frequently Asked Questions

What is the ISASP Science assessment for Grade 5?

It is Iowa's statewide summative science assessment for Grade 5, developed by Iowa Testing Programs and aligned to Iowa science standards across Life, Physical, and Earth and Space Sciences.

Who takes ISASP Science?

Students in the required science grades take ISASP Science unless they qualify for the DLM alternate assessment. For 2026–27 the required grades are 5, 8, and 11.

How many questions are on the official ISASP Science test?

Official ISASP Science is a 32-item test at each assessed grade. The current ISASP Science Test Specifications set the Total Number of Items per Test at 32 and distribute them across three reporting domains — Life Science, Physical Science, and Earth and Space Sciences — each targeted at 25–45% of the test (8–14 operational items) and delivered in clusters of 3–5 items built on a shared phenomenon. Iowa Testing Programs has announced that updated Science test specifications and blueprints for the 2027 ISASP will be published later in 2026, so the grade-11 counts are not yet set. Do not treat practice-bank length as the official count. Science is assessed statewide in grades 5, 8, and high school (grade 11 beginning 2026–27).

Is ISASP Science timed?

No. ISASP is untimed; schools use recommended session lengths for scheduling.

What score is considered meeting expectations?

Science continues prior reporting through spring 2026 administrations; ISASP will report four performance levels (Below, Approaching, Meeting, Exceeding) for Science after the spring 2027 administration (ITP/Pearson bulletin, Changes with ISASP Reporting for 2026).

Are these practice questions the real ISASP exam?

No. These free multiple-choice practice questions are a study aid aligned to Iowa science domains. They are not official ISASP items and do not replace phenomena analysis, scientific modeling, investigations, constructed responses, or the official assessment.
