Sample HI HSA Science G8 Practice Questions

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

1A pure sample of copper is made of only copper atoms. Which statement best describes copper in this sample?
A.It is a mixture of many different elements
B.It is an element made of one type of atom
C.It is a living cell that can reproduce
D.It is a form of energy with no mass
Explanation: An element is a pure substance made of only one kind of atom. A pure copper sample contains only copper atoms.
2Which process do plants use to convert light energy into chemical energy stored in sugars?
A.Cellular respiration
B.Photosynthesis
C.Transpiration
D.Fermentation
Explanation: Photosynthesis uses light energy, carbon dioxide, and water to make sugars that store chemical energy.
3Earth’s tectonic plates move because of energy from which main source?
A.Ocean tides pulling on coastlines
B.Heat from Earth’s interior driving mantle convection
C.Wind patterns in the upper atmosphere
D.Daily changes in sunlight at the surface
Explanation: Heat from Earth’s interior causes convection in the mantle, which helps move tectonic plates.
4A ball rolls down a hill and then slows to a stop on flat ground. Where did most of the ball’s kinetic energy go?
A.It was destroyed completely
B.It was transferred as heat and sound through friction
C.It turned into new matter inside the ball
D.It stayed locked as unused potential energy only
Explanation: Energy is conserved. Friction transfers kinetic energy into thermal energy and sound as the ball slows.
5In a food chain, grass → rabbit → hawk, which organism is a primary consumer?
A.Grass
B.Rabbit
C.Hawk
D.Soil minerals
Explanation: Primary consumers eat producers. The rabbit eats grass, so it is the primary consumer.
6Which weather instrument is designed to measure air pressure?
A.Thermometer
B.Barometer
C.Anemometer
D.Rain gauge
Explanation: A barometer measures atmospheric pressure, which helps forecast weather changes.
7Two students push a box with equal force in opposite directions. The box does not move. Which statement is most accurate?
A.There are no forces acting on the box
B.The forces are balanced, so the net force is zero
C.Gravity is the only force acting on the box
D.Unbalanced forces always make objects stay still
Explanation: Equal and opposite forces cancel, so the net force is zero and the box’s motion does not change.
8Offspring receive half of their chromosomes from each parent. What does this best explain?
A.Why all offspring look identical to one parent
B.Why offspring share traits with both parents
C.Why traits never vary within a species
D.Why DNA is found only in plant cells
Explanation: Each parent contributes genetic material, so offspring inherit a mix of traits from both parents.
9Which Earth layer is a solid, rocky outer shell broken into tectonic plates?
A.Inner core
B.Outer core
C.Lithosphere
D.Atmosphere
Explanation: The lithosphere is Earth’s rigid outer shell and includes the crust and uppermost mantle, divided into plates.
10When ice melts into liquid water at the same temperature of melting, which property stays the same?
A.The chemical identity of the substance
B.The arrangement of particles as a rigid lattice
C.The state of matter
D.The amount of thermal energy required to keep melting
Explanation: Melting is a physical change. Water remains H₂O; only its state changes from solid to liquid.

About the HI HSA Science G8 Exam

The Hawaiʻi State Assessment in Science (NGSS) Grade 8 is Hawaiʻi’s statewide middle-school science assessment. It measures NGSS performance expectations from the grades 6–8 band using phenomena-based clusters and stand-alone items. Scale scores range 400–600 with proficient performance at 500 or higher. OpenExamPrep free practice uses English-language four-option MCQs as a study aid for standards knowledge and task decisions. It is not an official HIDOE form, not a full simulation of item clusters, technology-enhanced tasks, equation entry, or constructed responses, and not a substitute for classroom instruction or the secure assessment.

HI HSA Science G8 Study Tips from Top Performers

1Practice interpreting multi-step phenomena with data tables, models, and energy diagrams.
2Review grades 6–8 NGSS, not only topics labeled grade 8.
3Include chemical reactions, force/motion, ecosystems, heredity, plate tectonics, and climate ideas.
4Explain how evidence supports a claim when kinetic energy, matter, or systems change.
5Use short mixed-domain practice sets weekly before the spring window.
