8. Which statement best explains why you can see yourself when you look at a mirror?
Light is refracted as it passes through the mirror.
Light is refracted, bouncing off the mirror.
Light is reflected, bouncing off the mirror.

A. Magnetism
B. Wind
C. Wind

6. Some students were investigating if the height that a ball was dropped would affect its bounce. The ball was dropped at 60 cm and at 80 cm. What statement is true of the results for each of the heights that the balls were dropped?
F. There was no difference in the results.
G. The ball dropped from 60 cm bounced 20 cm higher than
the ball dropped from 80 cm.
H. The ball dropped from 80 cm bounced higher than the ball dropped from 60 cm.
J. The ball dropped from 60 cm bounced higher than the ball dropped from 80 cm.
9. Some students were testing the effects of force on the motion of a water bottle. They set up the experiment picture above and rolled the full water bottle down both ramps. What question were the students most likely trying to answer?
A. How does mass affect the distance a full water bottle will roll?
B. How does friction affect the distance a full water bottle will roll?
C. How does the size of the water bottle affect the distance it rolls?
D. How does ramp height affect the distance a full water bottle will roll?
(2) Mrs. Giet’s class is playing tug of war at recess. They decide to play boys against girls. There are 11 girls and 6 boys. As soon as the game began, the girls were able to move the rope to their side. Why?
There was an equal amount of force pulling on each side making it unbalanced.
There was an equal amount of force pushing on each side making it unbalanced.
There was more force on the girls side making it unbalanced.
There was less force on the girls side making it unbalanced.
(4) John was blowing a feather across the dinner table. When he was blowing with all the breathe he had in him the feather went across the entire table, but when he just blew a little it only went to the edge of his plate. What statement best describes why the feather went across the table?
John used a strong blowing force causing the feather to travel a greater distance.
John used a weak blowing force causing the feather to travel a greater distance.
John used a pulling force to cause the feather to travel a greater distance.
John is a fire breathing dragon.
(7) Which scenario is showing gravity as the main force moving an object?
My pencil fell to the ground when I dropped it.
A plane taking off.
A feather floating in the wind.
A boy threw a ball up in the air.
(8) A car was traveling on a dirt road and on a concrete road. The car was able to travel on the concrete road without using as much force. Which description explains this scientific fact?
The dirt road has more friction because the surface is not smooth.
The concrete road has more friction because the surface is smoother.
The concrete road has more gravity because the surface is not smooth.
The concrete road has less gravity because the surface is not smooth.
(16) A ball has two forces acting on it. One force is pushing it to the left, and a larger force is pushing it to the right. In which direction will the ball move?
Right
Left
Up
Down
