Interim Review 1

A teacher gives students a beaker filled with sand and water. The teacher asks the students to pour the contents of the beaker through a filter as shown.

The purpose of this activity is to show that

• a new substance forms when a solid dissolves in a liquid

• onlv substances in different states of matter can be mixed

• a mixture can be separated into the original substances

• only substances in the same states of matter can be separated

A student divided the following items into two groups. The student placed five items in one group and two items in the other group.

The student most likely classified the items into the two groups based on their

• attraction to a magnet

• ability to conduct electricity

• physical state

• solubility in water

Students constructed this table to show physical properties of the objects they examined. The heading for the physical property in the last column is missing

Which heading belongs in the last column?

• Floats on the Surface of Water

• Dissolves Quickly in Water

• Conducts Electricity

• Insulates Thermal Energy

A student is separating mixtures using the equipment shown.

Which mixtures could BEST be separated using this equipment?

Select TWO correct answers.

• Sand and water

• Vinegar and oil

• Salt and pepper

• Sugar and water

• Vinegar and beans

A student uses the recipe shown to make food for hummingbirds.

Hummingbird Food Recipe

62 grams white sugar

237 milliliters water

1 - Boil water.

2 - Stir in sugar.

3 - Turn off heat.

4- Allow the liquid to cool.

The student pours the liquid into a hummingbird feeder. The student observes that there are no visible sugar particles in the liquid

Which inference can be made about the results of this recipe?

• The liquid is a solution because the sugar changes the temperature of the water.

• The liquid is a solution because the sugar dissolves evenly throughout the water.

• The liquid is not a solution because the original ingredients change their physical state.

• The liquid is not a solution because the original ingredients keep their individual properties.

A ball is at rest on the floor in a classroom. A student pushes the ball twice as shown by the arrows.

As the ball is rolling after Push 1, the student applies Push 2 to the ball. Which answer choice describes the change in motion due to the two pushes on the ball?

• The ball moves toward Position M and then comes to rest at Position K.

• The ball moves toward Position N and then comes to rest at Position L

• The ball moves toward Position K and then comes to rest at Position N

• The Ball moves toward Position L and then comes to rest at Position M

Students investigate how the amount of force applied to a wad of paper affects the distance that the paper travels. They create a catapult using a flexible piece of balsa wood. The wood is bent back, the wad of paper is placed on the end, and then the wood is released. A scale is used to measure the force. The students conduct five trials using the setup shown.

In order for the students to form a valid conclusion, which procedures should be completed during each trial?

Move the correct answer to each box in the table. Each answer may be used more than once or not at all.​ ​

Change the length of the balsa wood for each trial.

​ ​ (a)  

Use different wads of paper for each trial.

​ ​ (b)  

Use a metric ruler for each trial.

​ (c)  

Record data for force and distance for each trial.

​ (d)  

• No
• Yes

A student designed an electrical circuit for supplying light to two areas of a model house. The model will use a battery as the power source. The design must allow one light to be on when the other is off but also allow both lights to be on at the same time.

Which statement correctly describes one effect of the switches on the lights?

• When Switch I is closed and Switches 2 and 3 are open, both bulbs will light.

• When Switches 1 and 3 are closed and Switch 2 is open, only Bulb Y will light

• When Switches 2 and 3 are closed and Switch _ is open. both bulbs will light.

• When Switches 1 and 2 are closed and Switch 3 is open, neither bulb will light.

The diagram shows a spot on the wall formed by light from a light source.

Which of these best describes the behavior of the light along the path shown, after it leaves the light source?

• The light beam is refracted as it enters and leaves the prism and is reflected by the mirror

• The light beam travels through the prism without bending and is reflected by the mirror.

• The light beam is reflected and refracted through both the prism and the mirror.

• The light beam is reflected by the prism and is refracted by the mirror.
