A student measured out 10 mL of four clear liquids and added one drop of a different-colored dye to each liquid. One of the liquids was water. The student then carefully poured each liquid into a graduated cylinder and let the mixture settle for 30 minutes. The student observed that the liquids had separated into layers, as shown in the diagram.
Which of these procedures would help the student identify the layer of water?
Stir the liquids, let them settle, and then identify the bottom layer as water
Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water
Add water to the graduated cylinder, let the mixture settle, and then identify the layer that increases in volume as water
Carefully pour each layer into separate plastic containers, place the containers in a freezer, and then identify the liquid that takes the longest to freeze as water

The light is refracted or absorbed.
The light is reflected or absorbed.
The light is reflected or refracted.

What is the difference between refraction and reflection?
Light bends when it is reflected and bounces off when it is refracted.
Light bounces off when it is reflected and bends when it is refracted.

light does not strike dark objects.
Some students were investigating which surfaces would allow a ball to roll the farthest. Which of the following would be essential in their investigation?
Stopwatch, meter stick, calculator, soccer ball, 4½-foot-tall student
Grassy field, gym floor, concrete sidewalk, soccer ball, meter stick
Soccer ball, bowling ball, beach ball, stopwatch, meter stick
4-foot-tall student, 4½-foot-tall student, 5-foot-tall student, soccer ball, meter stick
Picking up a heavy box is much more difficult than putting it down. What is a likely explanation for this?
Pushing force is more difficult to accomplish than pulling force.
The force of gravity acts against you when you try to push something to the ground.
The action is less difficult because nothing is pulling the object toward the ground.
The force of gravity is pulling the box toward the ground which makes the action of putting the box down easier to do.
The force of friction was less on the left so the box moved to the right. What can be said about the effect of the force being applied by the above student on the left?
The force of magnetism was greater on the left so the box moved to the right.
The pull of gravity was greater on the right so the box moved to the right.
The pushing force was greater on the left so the box moved to the right.
The force of friction was less on the left so the box moved to the right.
Some students are designing an experiment to test the effect of force on an object. The force they are testing is friction. The students will investigate how far a car will slide when rolled across surfaces with different textures. The cars all have equal masses. Which of the following experimental procedures would be the best one for the students to use to conduct the above investigation?
First, create a ramp for each of the textures to be tested. Then, create a table to record your data. Next, roll each car down each ramp one time. Measure the distance the car traveled, and record the measurement in your table.
First, create a ramp for each of the textures to be tested. Make sure that all the ramps are the same height and length. Next, roll each car down each ramp three times. Each time, measure the distance the car traveled.
