#2 A clear, glass beaker is filled half-full of water. A plastic spoon is placed in the beaker, and one end rests against the top edge of the beaker. When viewed from the side, the bottom of the spoon does not line up with the top of the spoon. What causes this to happen?
Light rays are refracted in the water.
#5 Which question about the effect of force on an object could be answered by conducting a classroom experiment?
What type of surface produces the most friction?
#18 White Sands, New Mexico is a popular tourist attraction. People often say that it is an interesting place to visit because the landscape is different every year. What causes the landscape to be constantly changing?
The shape and size of the sand dunes are changed by the action of the wind.
#12 Based on the information above, which step in the sedimentary rock formation process is known as cementation?
Step 5
#11 A student designed an experiment to determine which type of ball would go the farthest using the trebuchet. The student used 3 types of balls and 3 counter weights, each with a different mass. What should the student do to improve the experiment?
Use the same counter weight for each trial
#1 A student designed the circuit above. What would most likely happen if the student closed Switch 1, Switch 2, and Switch 4?
Both of the bulbs would light up, but the bell would not ring.
#6 Some students were investigating which surfaces would allow a ball to roll the farthest. Which of the following would be essential in their investigation?
Grassy field, gym floor, concrete sidewalk, soccer ball, meter stick
#19 According to the information and image shown above, which of the following statements is NOT an example of how changing coastlines are the result of the action of wind and water?
Waves pull the saltwater from the beach and deposit the excess salt into the ocean.
#13 Based on the information above, which step in the sedimentary rock formation process is known as compaction?
Step 4
#3 The arrows in the diagrams below represent light. Which diagram best shows how a glass mirror would reflect light?
Answer Choice D
#8 Some students are designing an experiment to test the effect of force on an object. Which of the following experimental procedures would be the best one for the students to use to conduct the above investigation?
Answer J
#21 A family traveled to the Grand Canyon for Spring Break. They observed that a section of the Grand Canyon is a wide, U-shaped valley. What type of weathering most likely created this landform?
A slow-moving, large, and heavy glacier many year ago.
#14 Based on the information above, which step in the sedimentary rock formation process is known as weathering?
Step 1
#4 A student designed the circuit below. The bell is on, and both bulbs are lit. What could the student do to turn the bell off but keep the bulbs lit?
Remove Wire 2 only
#9 A teacher did a demonstration for her class. Which student has written a testable hypothesis?
Allison
#15 Which of the following statements describes the first step in the formation of sedimentary rocks?
Exposed rock and other surfaces are broken down by wind, water, ice, or other element
#10 A student wanted to test the effect of friction on a toy car rolling down a ramp. What conclusion could the student make based on this experiment?
The force of friction is least on the tile.
#16 Rocks will break down into smaller pieces. What are those pieces called?
Sediment
