Sample CT NGSS Science Grade 5 Practice Questions

Try these sample questions to test your CT NGSS 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.

1A student seals ice cubes in a plastic bag and lets them melt on a classroom windowsill. Which claim is best supported by the particle model of matter?
A.The water particles disappear when the ice melts
B.Melting creates brand-new particles that did not exist as ice
C.The same water particles stay in the bag but move more freely as liquid
D.The particles freeze harder after the ice turns to liquid
Explanation: Melting is a change of state. Water particles remain the same kind of matter; they gain energy and move more freely as a liquid. In a sealed bag, matter is conserved.
2Which observation is a physical property that can help identify a metal sample without changing what the metal is made of?
A.It burns and leaves ash
B.It is shiny and is attracted to a magnet
C.It reacts with vinegar and forms bubbles of a new gas
D.It forms a new solid when mixed with another chemical
Explanation: Shininess and magnetism are physical properties that can be observed without turning the metal into a different substance. Chemical reactions change the material into new products.
3Students measure 100 mL of water, add 20 g of salt, and stir until the salt can no longer be seen. What most likely happened to the salt?
A.It vanished, so the total mass dropped by 20 g
B.It turned into air and left the cup
C.The water destroyed the salt atoms completely
D.It dissolved and mixed with the water as tiny particles
Explanation: Dissolving spreads salt particles throughout the water so crystals are no longer visible, but the salt is still present. Total mass is conserved if nothing leaves the system.
4A cart is at rest on a flat classroom floor. What must happen for the cart to start moving?
A.Friction must disappear so the cart can begin rolling on its own
B.An unbalanced force must act on the cart
C.Balanced forces on all sides must stay equal forever
D.The cart must become warmer without any push or pull
Explanation: An object at rest stays at rest unless an unbalanced force acts on it. A push or pull that is not canceled by other forces starts the cart moving.
5When a rubber band is stretched and then released so it snaps a paper wad across a desk, how is energy changing?
A.New energy is created from nothing when the rubber band snaps
B.Stored energy in the stretched rubber band transfers into motion of the paper wad
C.All energy is destroyed the moment the rubber band is released
D.The paper wad gains energy only if gravity disappears
Explanation: Stretching stores elastic energy in the rubber band. When released, that stored energy transfers into the kinetic energy of the moving paper wad. Energy is transferred, not created from nothing.
6A student hears a drum from across the gym. Which statement best describes how the sound travels?
A.Sound particles leave the drum and land only on the eardrum as solid bits
B.Sound can travel only through empty space with no air at all
C.Sound travels as vibrations through the air between the drum and the ear
D.Sound reaches the ear only if light from the drum is also visible
Explanation: Sound is produced by vibrations and travels as waves through a medium such as air. You can hear a drum even when you are not looking at it.
7Which change is most clearly a chemical change?
A.Ice melting into liquid water
B.Wood burning and leaving ash and smoke
C.Paper tearing into smaller pieces
D.Water freezing into ice cubes
Explanation: Burning wood produces new substances such as ash, smoke, and gases. Melting, freezing, and tearing change form or size without making new kinds of matter.
8A lamp lights when a battery, wires, and bulb form a complete loop. Why does the bulb go dark if one wire is disconnected?
A.The battery runs out of stored energy the moment a wire is removed
B.Light can only travel through broken wires
C.The complete path for electric energy is broken
D.The bulb uses up all the air in the room
Explanation: A complete circuit provides a closed path for electric energy to reach the bulb. Opening the path stops the transfer of energy that lights the bulb.
9Two magnets are placed so their north poles face each other. What is most likely to happen?
A.The magnets pull together, because magnets always attract each other
B.Nothing happens unless the magnets are touching
C.The magnets lose their magnetism when like poles face each other
D.The magnets push apart
Explanation: Like magnetic poles repel, so two north poles push away from each other. This is a non-contact force: the magnets act on each other across a gap without touching, and neither magnet is changed by the interaction.
10Which material is best for a pot handle if the goal is to keep a cook’s hand cooler?
A.Metal that quickly transfers heat
B.A thin bare wire wrapped around the handle
C.Wood or plastic that transfers heat more slowly
D.A handle made only of solid aluminum foil
Explanation: Materials that transfer heat slowly are better insulators for handles. Wood and many plastics keep more heat in the pot metal and less in the hand.

About the CT NGSS Science Grade 5 Exam

The Connecticut NGSS Science Assessment — Grade 5 is Connecticut’s statewide mastery examination for science in grade 5. It measures Next Generation Science Standards understanding across the grades 3–5 band in Life Science, Physical Science, and Earth and Space Science using phenomena-based item clusters and stand-alone items on the Cambium online Test Delivery System. Results include an overall science score and discipline claim scores. OpenExamPrep free MCQ practice is an English-language study aid aligned to NGSS domains—not official secure content or a full simulation of multi-part clusters and technology-enhanced tasks.

CT NGSS Science Grade 5 Study Tips from Top Performers

1Use official NGSS practice and training items on the Connecticut Comprehensive Assessment Program Portal so students learn tools and interaction types.
2Review NGSS Performance Expectations for grades 3–5, not only grade 5 labels—the Grade 5 form samples the band.
3Practice explaining phenomena with evidence: claim–evidence–reasoning across Life, Physical, and Earth/space contexts.
4Include questions that use graphs, tables, and fair-test design ideas; official items integrate Science and Engineering Practices.
5Mix matter, forces/energy, ecosystems, heredity, weather/Earth systems, and resource/environment topics for balanced discipline coverage.
6Use short, frequent practice across the year rather than cramming only in the spring window.
