1A student pours a spoonful of sugar into a glass of warm water and stirs. The sugar disappears from sight, but the water tastes sweet. What is the best explanation?

A.The sugar broke apart into pieces too small to be seen, and those pieces are still in the water

B.The sugar was destroyed and no longer exists

C.The sugar turned into water

D.The sugar floated out of the glass into the air

Explanation: Matter is made of particles that are far too small to see. When sugar dissolves, its particles spread out among the water particles instead of disappearing. The sweet taste is direct evidence that the sugar is still there.

2A student blows up a balloon and ties it shut. Which statement about the air inside the balloon is correct?

A.Air is matter made of particles too small to see, and it takes up space

B.Air is not matter because it cannot be seen

C.Air is made of one solid piece that fills the balloon

D.Air only becomes matter when it is cold

Explanation: Air is a gas, and gases are matter. Air is made of particles far too small to see. Those particles push outward on the balloon, which is why the balloon holds its shape and takes up space.

3A student puts a few drops of food coloring into a still glass of water and does not stir. After several minutes the color has spread through the whole glass. Which model best explains what happened?

A.Particles of the coloring, too small to see, moved and spread among the water particles

B.The color soaked into the glass and then leaked back out

C.The water changed into food coloring

D.The coloring evaporated and then fell back down as color

Explanation: A particle model explains the result: the coloring is made of particles too small to see, and those particles keep moving and mix in among the moving water particles. Over time this spreading colors the entire glass even with no stirring.

4A student seals a small amount of rubbing alcohol in a clear bag. The next day the liquid is gone, but the bag looks slightly puffed up. What is the best explanation using a particle model?

A.The alcohol particles spread out into the space in the bag as a gas and are still inside

B.The alcohol particles passed through the sealed plastic and left the bag

C.The alcohol particles were used up and no longer exist

D.The alcohol particles turned into plastic

Explanation: In a sealed bag, matter cannot get out. The liquid alcohol became a gas, so its particles spread far apart and filled the space in the bag. That is why the liquid seems to vanish while the bag puffs up.

5Two students argue about a sealed jar of air. One says the jar is empty. Which piece of evidence best supports the claim that the jar actually contains matter?

A.A sealed jar of air has slightly more mass on a balance than the same jar with the air pumped out

B.The jar looks clear when you hold it up to the light

C.The jar feels smooth on the outside

D.The jar makes a sound when it is tapped

Explanation: Matter has mass, so measuring mass is the strongest test. A jar of air weighs slightly more than the same jar with the air removed, which is evidence that air is made of particles that are matter even though they cannot be seen.

6A student wants to build a model showing why a gas can be squeezed into a smaller space but a liquid cannot be squeezed much at all. Which model would work best?

A.Marbles spread far apart in a box for the gas, and marbles packed closely together for the liquid

B.One large marble for the gas and one small marble for the liquid

C.A solid block for the gas and a hollow tube for the liquid

D.A drawing of a cloud for the gas and a drawing of a puddle for the liquid, with no particles shown

Explanation: A useful particle model shows spacing. In a gas the particles are far apart with empty space between them, so they can be pushed closer. In a liquid the particles already touch, so there is very little space left to squeeze out.

7A student places a sealed container of water on a balance. The container and water together have a mass of 250 grams. The student puts the sealed container in a freezer until the water becomes ice, then weighs it again. What mass should the balance show?

A.250 grams

B.Less than 250 grams, because ice is lighter than water

C.More than 250 grams, because freezing adds cold

D.It cannot be predicted

Explanation: Cooling changes the state of the water but does not add or remove matter. Because the container is sealed, all of the same particles are still inside, so the total mass stays 250 grams.

8A student measures 30 grams of salt and 170 grams of water, then stirs the salt into the water until it dissolves completely. What is the mass of the salt water?

A.200 grams

B.170 grams, because the salt dissolved

C.140 grams

D.It depends on how long the student stirs

Explanation: When substances are mixed, the total mass is conserved. The salt particles are still present in the water, so the mass of the mixture equals 30 grams plus 170 grams, or 200 grams.

9A student burns a candle that starts with a mass of 50 grams. After it burns for a while, the candle that is left has a mass of 35 grams. A classmate says 15 grams of matter was destroyed. How should the student respond?

A.The 15 grams became gases and soot that went into the air, so the matter still exists

B.The classmate is right, because burning destroys matter

C.The 15 grams turned into light, which has mass

D.The 15 grams sank into the candle holder

Explanation: Matter is conserved during burning. The wax that seems to disappear combines with gases from the air and leaves as gases and tiny soot particles. If every product could be collected and weighed, the total mass would still be accounted for.

10A student wants to show that mass is conserved when baking soda and vinegar are mixed and bubbles form. Which setup would give the best evidence?

A.Mix them inside a sealed plastic bottle and weigh the whole bottle before and after

B.Mix them in an open cup and weigh the cup before and after

C.Mix them in an open bowl and only weigh what is left in the bowl

D.Weigh the baking soda before and the vinegar after

Explanation: The bubbles are a gas. If the container is open, that gas escapes and the measured mass drops, which hides the conservation of matter. Sealing the container keeps every product inside so the balance reading stays the same.

Nebraska NSCAS Science Grade 5 Study Tips from Top Performers

1Connect a force to its effect: pushes and pulls can change an object's speed or direction, and gravity always pulls toward Earth's center.

2Trace energy as it moves and changes form (light, heat, sound, motion), and notice that some energy is always transferred away as heat.

3For weather and climate, distinguish daily weather (short-term conditions) from climate (long-term patterns over years).

4Relate an organism's structures to their functions (roots take in water; beaks match food; thick fur insulates) and to survival in its environment.

5Read data tables, models, and described investigations carefully before choosing an answer in phenomena-based scenario items.
