Which statement is a measurement of what is shown in the picture?

• Sample X is a different color than sample Y.

• Sample X and sample Y are liquids.

• Sample X fills more of the container than sample Y.

• Sample Y has a volume of 50 milliliters.

Alan plans to draw models to show the state of matter of each sample. He will do this by drawing how the particles are arranged in each sample.

Is it possible to use only the models to identify which sample is X and which is Y?

• No, because the samples are both made of the same elements.

• No, because the samples are both liquids.

• Yes, because the samples are different colors.

• Yes, because the samples have different volumes.

Kate is observing properties of matter. Which of these properties can't she observe using her senses?

• hardness

• color

• mass

• texture

Sam wants to draw a model to show that the particles of matter are too small to be seen. Which would best help him to show this concept?

• Sam should model the temperature of a sugar mixture.

• Sam should model the mass of a sugar cube.

• Sam should model the elements that make up water.

• Sam should model the height, width, and length of a block of ice.

The different colors of the foam balls are meant to show that the balls represent different elements, so the model shows that carbon dioxide is a (an)...

Carbon dioxide is a gas found in the air. Simone uses foam balls and pencils to model carbon dioxide. How can Simone’s model be changed to show a different kind of matter?

• Use larger foam balls.

• Connect another black foam ball to the model.

• Connect the foam balls using shorter pencils.

• Use rubber balls instead of foam balls.

Petra has a container of water. Based on what she knows about particles in matter, she draws a model of the water particles before her investigation and after her investigation. Petra’s model is shown below. What did Petra most likely do in her investigation?

• She took the lid off the container of water.

• She heated the water.

• She took the lid off the container of water.

A group of students carries out an investigation. They observe and measure different properties of matter. Their data for four samples of matter are shown in the table. Next, the group places one of the samples in a beaker of 100 milliliters of water and stirs the contents. After 10 minutes, they notice that there is a solid left in the beaker. Which sample did they place in the beaker?

• x

• y

• z

• w
