Cameron tests four rocks. All of the rocks are gray. He wonders whether they are made of the same material. He does the following tests on each of the rocks to find out whether the rocks are made of the same or different materials: He examines the surface with a magnifying glass. He drags the rock across a piece of glass. If the rock is harder than glass, the rock will scratch the glass. If the rock is not harder than glass, nothing will happen to the glass. He puts a drop of vinegar on the rock. For some materials, the vinegar will cause bubbles to form. For other materials, nothing will happen. The data from his tests are in the table. Carlos believes that Rocks 1 and 4 are made of the same material. What data supports his conclusion? Select all that apply.

• Rocks 1 and 4 scratch glass.

• Rocks 1 and 4 do not have large holes.

• Rocks 1 and 4 have the same surfaces.

• Vinegar does not make Rocks 1 and 4 bubble.

Derrick has a glass of water. After he adds a few drops of black dye to it, he can see black swirls in the water. After a while, all of the water is gray. If you could zoom in to see what the water and dye are made of, which set of models best shows how the water turned grey?

Julie and Michael have two white materials made up of crystals. They need to figure out whether they are the same or different. What observations would be useful for determining whether they are the same material? Choose all that apply.

• the size of the crystals

• the weight of the material

• whether the material dissolves in water

• whether adding vinegar makes bubbles

• the temperature at which it melts and turns into a liquid

Gail adds sugar to a cup of warm water, the sugar dissolves. She wonders whether the sugar is still there since she cannot see it anymore. She thinks the sugar must still be there because the water tastes sweet. Tim is not sure if the sugar is still there. The sugar taste is still there, but he believes the sugar may be gone since he cannot see it. Which tests do you think will help them determine whether the sugar is still there? Circle all that apply.

• Mix the sugar with cold water and hot water.

• Add more sugar to the water, and observe what happens.

• Weigh the sugar and water separately before they are combined; after they have been combined, weigh the solution.

• Have more students taste the material, and collect their observations.

• Remove the water by letting the container sit until all of the water evaporates.

Matter that is made up of one or more substance is called a ______________.

• Soluble

• Atom

• Mixture

• Dissolve

Matter that is made up of only one kind of atom or molecule is called a ________________.

• Soluble

• Model

• Mixture

• Substance

Which of the following best describes the process of matter amplification in a scientific context?

• Increasing the mass of a substance by adding more atoms

• Enhancing the properties of a material through chemical reactions

• Expanding the volume of a gas by heating

• Converting a solid directly into a gas

In an experiment to amplify matter, a scientist observes that the density of a material increases. What could be a possible explanation for this observation?

• The material absorbed moisture from the air

• The material underwent a chemical reaction forming a denser compound

• The material was heated causing it to expand

• The material was placed in a vacuum
