5th Grade Science Quarter 2 Review

The ingredients in some mixtures maintain their physical properties. In which of the

following mixtures do all of the ingredients maintain their physical properties?

• Water, salt, and sand

• Pretzels, chocolate chips, and raisins

• Ice, lemon juice, and sugar

• Chocolate powder and milk

A table of different properties of four samples of matter is shown.

Which conclusion can be made about the samples based on the table?

• Sample 1 is made of plastic.

• Sample 2 is made of metal.

• Sample 3 is attracted to magnets.

• Sample 4 is less dense than water.

A student conducts the investigation shown in the diagram. In this investigation, a pullback toy car is pulled back and released. The student measures and records the distance the car travels. The student then adds one penny on top of the car for each of the next two trials.

Which question is the student most likely trying to answer with this investigation?

• How does the mass of the car affect the distance it will travel?

• How does the texture of the road affect the distance it will travel?

• How does the type of car affect the amount of pennies it can carry?

• How does the distance the car travels affect the number of pennies it can carry?

A student builds a circuit allowing the lightbulbs to light, the buzzers to make sound,

and the motors to turn.

Which two switches can be open and still allow all of the parts to work?

• Switches 1 and 3

• Switches 1 and 4

• Switches 2 and 3

• Switches 3 and 4

A student conducts the investigation shown in the diagram. In this experiment a paper cup hangs from a string tied to a single uncooked spaghetti noodle. The student measures and records the mass of a penny. The student then adds pennies to the paper cup one at a time.

Which question is the student most likely trying to answer with this investigation?

• How many spaghetti noodles will it take to hold up the mass of a penny?

• How much force will it take to break the spaghetti noodle?

• How long should the string that holds the paper cup be in order to support the

  greatest mass of pennies?

• How does the distance between the two chairs affect the amount of force it

  takes for the spaghetti noodle to break?

Some students are feeding a crab in an aquarium. They use tongs to place the food directly in front of the crab. The students look through the side of the aquarium. They notice that the image of the tongs appears to break as the tongs enter the water.

Which property of light are the students observing in this situation?

• Light can be refracted and separated into different colors as it moves from air to a different medium.

• Light is refracted as it moves from one medium to another medium.

• Light travels in a straight line and can be reflected off the surface of water.

• Light is absorbed by water and reflected off glass.

Students design an experiment to determine how much force is needed to move blocks of wood of different masses slowly across a lab table.

Which procedure should students include in their design?

• Conduct five trials, pulling a different side of each block each time

• Conduct five trials, using a different scale to pull each block of wood

• Conduct five trials, using a different table for each trial

• Conduct five trials, pulling each block of wood in the same way for each trial

A student constructs the circuit shown for a science demonstration.

With the switches in these positions, which lights are on?

• All the lights

• Lights 1 and 2 only

• Lights 3 and 4 only

• None of the lights

A student adds salt to their soup. Which property of the salt remains the same when the salt is stirred in the soup?

• The color of the salt

• The texture of the salt

• The taste of the salt

• The size of the salt crystals

A student conducts an investigation by shining a flashlight toward a flat mirror. The student changes the angle of the mirror and observes the path of the reflected light.

As the mirror changes direction, the light reaching the mirror can reach the ceiling because the light —

• travels in straight lines and reflects from the surface of the mirror

• enters the mirror and changes direction when it is refracted by the back of the

  mirror

• refracts in the glass of the mirror and is spread out all over the room

• travels through air and does not change its direction in air
