Science Topic 1 Review

Alan has two samples of matter as shown in the picture. 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 three properties can she observe using her senses?

• Hardness

• Color

• Mass

• Texture

Santosh is investigating a property of matter. He connects a lightbulb to a battery using different materials. He tests copper wire, string, and aluminum wire and observes how well the lightbulb works. Which property of matter is Santosh most likely investigating?

• Conductivity

• Solubility

• Color

• Texture

Claire is studying properties of matter. She finds the following data in a science book. Claire has a sample of matter and knows that the sample is one of the four substances in the table. Her sample is white and has a crystal appearance. Which TWO substances could Claire have?

• W

• X

• Y

• Z

Claire discovers that her sample does not have a solution. Can the sample now be identified based on the data in the chart?

• Yes, she can identify it as substance Y.

• No, she needs to know if it forms a conductive solution.

• Yes, she can identify it as substance Z.

• No, because more than one substance has the same properties.

Gian investigates a property of matter using a balance. Which best explains what Gian is doing.

• He is observing a property because he is comparing the property to a standard unit of measure.

• He is measuring a property because he is comparing the property to a standard unit of measure.

• He is observing a property because he is only using his senses to gather information.

• None of the Above

Which conclusion is supported by Gian's investigation?

• The matter weighs more than 20 grams.

• The matter weighs 20 grams.

• The matter weighs less than 20 grams.

• None of the Above

Which other two properties can Gian identify without using any additional materials?

• color

• solubility

• magnetism

• texture

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.

• She stirred the water.

• She heated the water.

• She took the lid off the container of water.

• She poured the water into a larger container.
