Question 7

A hot-air balloon pilot controls the balloon by adding or releasing hot air as the balloon flies high in the sky. Which of the following best describes why hot air is used to make the balloon rise?

Accepted Answer

The hot air molecules move quickly, bouncing off each other and the walls of the balloon to create energy.

Answer

The hot air molecules stay still, which creates energy that helps the balloon to float.

Answer

The hot air molecules disappear after they are created, causing the balloon to rise.

Answer

The hot air molecules are heavy, which creates energy and causes the balloon to rise in the air.

Question 8

When the ice froze, it lost some water in the process.

Question 9

Georgia has been learning about matter in science class. Her class has created a chart that summarizes the ideas that they have discovered. The teacher sets up stations to allow students to further investigate matter. Refer to the below chart as you consider each of their investigations. When Greta 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. Sam 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. They talk about how they can decide whether the sugar is still there. Which tests do you think will help them determine whether the sugar is still there? Mark all that apply.

Accepted Answer

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

Accepted Answer

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

Answer

Mix the sugar with cold water and hot water.

Answer

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

Answer

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

Question 10

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.

Accepted Answer

Rocks 1 and 4 scratch glass.

Accepted Answer

Rocks 1 and 4 have the same surfaces.

Accepted Answer

Vinegar does not make Rocks 1 and 4 bubble.

Answer

Rocks 1 and 4 do not have large holes.
