Sample KĀʻEO Science G8 Practice Questions

Try these sample questions to test your KĀʻEO Science G8 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which organelle is the primary site of photosynthesis in plant cells?
A.Chloroplast
B.Mitochondrion
C.Nucleus
D.Ribosome
Explanation: Chloroplasts contain chlorophyll and carry out photosynthesis, converting light energy into chemical energy stored in sugars.
2In a food chain, which organisms capture energy from sunlight first?
A.Primary consumers such as insects
B.Secondary consumers such as small fish
C.Decomposers such as fungi
D.Producers such as plants and algae
Explanation: Producers use photosynthesis (or, rarely, chemosynthesis) to convert energy into organic matter that supports the rest of the food web.
3What is the main function of the cell membrane?
A.To produce food from sunlight in animal cells
B.To give plant cells their rigid box-like shape alone
C.To control what enters and leaves the cell
D.To store the cell's DNA permanently outside the nucleus
Explanation: The selectively permeable cell membrane regulates the movement of materials into and out of the cell.
4A trait that helps an organism survive and reproduce in its environment is best described as a(n)
A.extinction event
B.adaptation
C.mutation that is always harmful
D.learned habit with no genetic basis only
Explanation: An adaptation is a heritable trait that increases fitness in a given environment over generations of natural selection.
5Which process releases energy from glucose for use by cells?
A.Cellular respiration
B.Photosynthesis
C.Transpiration
D.Evaporation
Explanation: Cellular respiration breaks down glucose (often with oxygen) to release usable energy as ATP for cellular work.
6In sexual reproduction, offspring receive genetic material from
A.only one parent and never any DNA mixing
B.the environment alone with no parents
C.viruses that replace all parent DNA
D.two parents
Explanation: Sexual reproduction combines genetic material from two parents, producing genetically varied offspring.
7Which body system transports oxygen and nutrients throughout the human body?
A.Skeletal system alone
B.Integumentary system alone
C.Circulatory system
D.Digestive system alone
Explanation: The circulatory system (heart, blood, vessels) moves oxygen, nutrients, hormones, and wastes around the body.
8A population of beetles includes green and brown individuals. Birds more easily see green beetles on brown bark. Over many generations, brown beetles become more common. This best illustrates
A.complete random extinction of every green allele in one day
B.natural selection
C.individuals choosing to change color during their lifetime as a permanent genetic fix
D.all mutations being caused by the birds directly
Explanation: Natural selection favors traits that improve survival and reproduction; better-camouflaged brown beetles leave more offspring over generations.
9Which statement best describes a gene?
A.A segment of DNA that codes for a protein or functional product
B.An entire organism's complete set of habitats
C.A single atom that forms all living tissue
D.A type of organ that pumps blood
Explanation: A gene is a DNA sequence that provides instructions for making a protein or other functional product that can influence traits.
10Decomposers such as bacteria and fungi are important in ecosystems mainly because they
A.produce most of the oxygen by photosynthesis in deep ocean trenches only
B.prevent all energy from entering food webs
C.eliminate the need for producers
D.recycle nutrients by breaking down dead organisms
Explanation: Decomposers break down dead material and waste, returning nutrients to soil and water for producers to reuse.

About the KĀʻEO Science G8 Exam

KĀʻEO Science Grade 8 is Hawaiʻi’s statewide Hawaiian-medium science assessment for Kaiapuni immersion students in grade 8. HIDOE administers KĀʻEO science in grades 5 and 8. OpenExamPrep free practice is an English-language four-option MCQ study adaptation of assessable standards knowledge—not an official KĀʻEO translation, not a Hawaiian-medium testing environment, and not a substitute for authentic Kaiapuni reading, writing, listening, speaking, multi-step modeling, constructed responses, or the secure assessment.

Assessment

Question count not published by the exam provider

Time Limit

School-scheduled within the statewide KĀʻEO window. SY 2025–26 KĀʻEO window: Language Arts & Mathematics grades 3–8 and Science grades 5 & 8 open 04/01/26 and close 05/28/26 (subject to change).

Passing Score

KĀʻEO reports one overall scale score per content area mapped to four achievement levels — Level 1 Beginning, Level 2 Developing, Level 3 Proficient, Level 4 Distinguished. Cut scores were set by standard setting (2016 for grades 3–4 HLA and mathematics, 2019 for grades 5–8 and grade 8 science, 2023 for grade 5 science) and are not republished as a single public percentage; read the score report for the year administered.

Exam Fee

Free to students and families; administered for Kaiapuni Hawaiian language immersion students in Hawaiʻi public and public charter schools (no separate family registration fee published). (Hawaiʻi State Department of Education (HIDOE) with University of Hawaiʻi–Mānoa partners)

KĀʻEO Science G8 Exam Content Outline

Largest reported subscale (39 points in the 2022 KĀʻEO technical report)

ʻO Ko Lalo (all on and below the earth)

Earth and life systems below the horizon: organisms and heredity, ecosystems and cycling of matter, geology and plate processes, and ocean systems.

Reported subscale (see the KĀʻEO technical report for the year administered)

ʻO Ko Luna (all above the earth)

Sky, atmosphere and space: solar system motions, seasons, weather and climate patterns, and energy arriving from the sun.

Smallest reported subscale (14 points in the 2022 KĀʻEO technical report)

ʻO Ko Halawai (the meeting place / horizon)

A grade 8 subscale unique to KĀʻEO. HIDOE reports it separately but does not publish a public content definition, so treat it as the interface where sky and earth systems meet.
