5th QSE 2 Prep

A student wants to build a circuit with four lightbulbs and one bell. The student wants to place a switch in the circuit so that only one light will still be on and the bell will still ring when the switch is opened. Which of these circuits should the student build?

Students investigate force. The masses they use begin at rest on the ramp. The set up the students use is shown below.

Which change will reduce the amount of force needed to move the masss?

• Decrease the height of the ramp

• Increase the height of the ramp

• Add an additional mass

• Pull the spring scale with two hands

A student compares the physical properties of the four objects shown.

Which of these physica l properties do all four objects have in common?

• They all have the same physical state and conduct electricity

• They all conduct electricity and attract the same metal objects.

• They all attract the same metal objects and are not soluble in water.

• They all are not soluble in water and have the same physical state.

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

• Ice, lemon juice, and sugar

• Choclate powder and milk

• Pretzels, chocolate chips and raisins

A student observes an orange falling from a tree. The student designs an experiment to study whether the height of an object affects the length of time it takes for it to hit the ground. The student makes a hypothesis that the length of time it takes an object to hit the ground depends on its height. Some of the steps in the student's experiment are described below.

Which of these most likely completes Step 3 in the student's experiment?

• Use a measuring tape to measure the distance the golf ball travels from the ladder for each trial.

• Use a stopwatch to measure the time it takes the golf ball to stop moving from the release for each trial.

• Use a measuring tape to measure the distance the golf ball travels from the release to the ground for each trial.

• Use a stopwatch to measure the time it takes the golf ball to travel from the release to the ground for each trial.

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 taste of the salt

• The texture of the salt

• The size of the salt cyrstals

What happens when light travels through a microscope lens?

• Light travels through the microscope lens without changing direction.

• Moving in straight lines causes light to increase in brightness.

• Light refracts through the lens of the microscope.

• Moving in straight lines keeps light from reflecting.

• Light travels through the microscope lens without changing direction.

• Moving in straight lines causes light to increase in brightness.

• Light refracts th rough the lens of the microscope.

• Moving in straight lines keeps light from reflecting.

A thin beam of light is shown in this picture.

What does the picture demonstrate about light?

• Light and its reflections travel in straight lines.

• Light cannot reflect from more than one surface.

• Light that goes through water cannot travel in stra ight lines.

• Light can travel in a circular path.
