Key Facts: NYS Grade 8 Science Exam

The NYS Grade 8 Intermediate-Level Science Test is New York's free, NGSS-aligned state assessment that measures eighth-grade mastery of the P-12 Science Learning Standards across physical, life, and earth and space science using phenomenon-based multiple-choice and constructed-response items, with results reported in four performance levels.

1During a chemical reaction in a sealed container, the total mass of the substances is measured before and after the reaction. According to the law of conservation of mass, what should the measurement show?
A.The total mass stays the same before and after the reaction
B.The total mass increases because new substances are made
C.The total mass decreases because atoms are destroyed
D.The total mass doubles because bonds are broken
Explanation: In a chemical reaction, atoms are rearranged but never created or destroyed, so the total number of each type of atom is the same before and after. In a sealed (closed) container, no matter can enter or leave, so the total mass is conserved and stays constant.
2A student pushes a box across the floor and then pushes it the same way on ice. The box slides much farther on the ice. Which statement best explains why?
A.There is less friction between the box and the ice
B.Gravity is weaker over the ice than over the floor
C.The box has less mass when it is on the ice
D.There is no force acting on the box on the ice
Explanation: Friction is a force that opposes motion between two surfaces in contact. Ice is much smoother and slipperier than the floor, so it produces far less friction, allowing the box to keep sliding much farther before it stops.
3A skateboarder rolls down a ramp from the top to the bottom. As the skateboarder descends, how does the energy change?
A.Gravitational potential energy is transformed into kinetic energy
B.Kinetic energy is transformed into gravitational potential energy
C.Energy is created as the skateboarder speeds up
D.Total energy is destroyed because of friction
Explanation: At the top of the ramp the skateboarder has the most gravitational potential energy because of their height. As they roll down, height decreases and speed increases, so potential energy is transformed into kinetic energy (energy of motion).
4Sound travels from a speaker to a listener's ear through the air. Which statement correctly describes how sound moves through the air?
A.It travels as a wave that makes air particles vibrate back and forth
B.It travels as particles of sound that fly through empty space
C.It travels only when there is no matter in the way
D.It travels faster through a vacuum than through air
Explanation: Sound is a mechanical wave that needs a medium such as air to travel. The wave moves energy by making air particles vibrate back and forth, which passes the disturbance along to the listener's ear without the air itself traveling to the ear.
5A scientist looks at plant tissue under a microscope and sees many small compartments, each with its own boundary and contents. These compartments are the basic units of the plant. What are they called?
A.Cells
B.Atoms
C.Organs
D.Molecules
Explanation: Cells are the smallest unit of structure and function in living things. All organisms are made of one or more cells, and observing tissue under a microscope reveals these small membrane-bound compartments as the basic building blocks of the plant.
6In a cornfield, some plants produce ears with many different kernel colors. This variation among the corn plants is mostly caused by differences in which of the following?
A.The genes the plants inherited from their parents
B.The amount of sunlight each plant received last week
C.The temperature of the soil on a single day
D.The order in which the seeds were planted
Explanation: Traits such as kernel color are controlled by genes that are passed from parent plants to offspring. Differences in the genes (genetic variation) inherited from the parents lead to the variety of kernel colors seen across the corn plants.
7Two organisms share many similar bone structures in their limbs even though they live in different environments. Scientists use this similarity as evidence that the two organisms most likely
A.share a common ancestor
B.live in exactly the same habitat
C.are the same species today
D.never change over time
Explanation: Similar bone structures, called homologous structures, suggest that organisms inherited those features from a shared ancestor in the past. This anatomical evidence is one of the main lines of support for evolutionary relationships between species.
8In a meadow ecosystem, hawks eat field mice, and field mice eat grass seeds. If a disease greatly reduces the number of field mice, what is the most likely short-term effect?
A.The hawk population will likely decrease because it has less food
B.The grass will immediately disappear from the meadow
C.The hawk population will increase because there is more food
D.The number of grass seeds will decrease right away
Explanation: Hawks depend on field mice as a food source. If the mouse population drops sharply, the hawks have less food available, so their population is likely to decrease as well. This shows how organisms in a food chain depend on one another.
9Scientists find that earthquakes and volcanoes occur most often along the edges of large sections of Earth's outer layer. These large moving sections are called
A.tectonic plates
B.ocean currents
C.weather fronts
D.magnetic poles
Explanation: Earth's rigid outer layer is broken into large pieces called tectonic plates that slowly move. Most earthquakes and volcanoes happen at plate boundaries, where plates collide, separate, or slide past one another, releasing energy and allowing magma to reach the surface.
10A weather forecaster reports that a cold front is moving into the area. As the cold air pushes under the warmer air ahead of it, what weather change is most likely?
A.Clouds and storms may form as the warm air is forced upward
B.The sky will always become completely clear and calm
C.The temperature will rise steadily for several days
D.The air pressure will stay exactly the same all day
Explanation: When a cold front moves in, the denser cold air pushes under the warmer air and forces it upward. As the warm, moist air rises and cools, water vapor condenses, which can form clouds and trigger showers or thunderstorms along the front.

About the NYS Grade 8 Science Exam

The New York State Grade 8 Intermediate-Level Science Test is a state summative assessment that measures how well eighth graders have learned the New York State P-12 Science Learning Standards, which are New York's adaptation of the Next Generation Science Standards (NGSS). First administered in its revised, NGSS-aligned form in Spring 2024, the test covers science from grades 6 through 8 and is built around real-world phenomena rather than simple recall. It is a computer-based test given in a single session, using multiple-choice questions along with constructed-response and technology-enhanced items such as drag-and-drop and dynamic graphing. Roughly 60 percent of the credit comes from multiple-choice questions and about 40 percent from constructed-response items. The test emphasizes applying science and engineering practices and crosscutting concepts across physical science, life science, and earth and space science. Results are reported in four performance levels, and the test is free to students.

NYS Grade 8 Science Study Tips from Top Performers

1Study all three areas, physical science, life science, and earth and space science, since each makes up roughly a third of the test.
2Practice applying concepts to new, real-world phenomena rather than just memorizing facts, because most items are built around scenarios you may not have seen before.
3Master core physical science ideas such as conservation of mass in reactions, forces and motion, energy transformations, and how waves carry energy.
4Review key life science ideas including cell structure, photosynthesis and respiration, inheritance and variation of traits, ecosystem energy flow, and natural selection.
5Learn earth and space science topics like plate tectonics, the water cycle, weather and climate, and the motions of Earth, the Moon, and objects in the solar system.
6Use data tables, graphs, and diagrams when answering, since many items present models and ask you to analyze evidence and draw conclusions.
