color of the skin

size of rotten spots
c)
length of worms inside
d)
number of broken branches

What is the best question for students to investigate that would help explain the results of this demonstration?
a)
How long did it take for the cube in Beaker 2 to sink?
b)
Would a different sized beaker provide the same results?
c)
Will the cube in Beaker 1 sink if more liquid was added?
d)
What caused one cube to float and the other cube to sink?
6.
Which of the following statements would best explain the results of this demonstration?
a)
The cube in Beaker 1 has a lower density than the cube in Beaker 2.
b)
The liquid in Beaker 1 has a higher density than the liquid in Beaker 2
c)
The cube in Beaker 1 is made from a different material than the cube in Beaker 2.
d)
The liquid in Beaker 1 has the same chemical composition as the liquid in Beaker 2.
7.

8.
The bodies of many cars are designed to compress or crumple during an accident.
Why are cars built with a crumple zone?
Why are cars built with a crumple zone?
a)
The crumple zone is made from cheaper materials, so the car costs less to make.
b)
The crumple zone is made from cheaper materials, so it costs less to repair after an accident.
c)
The crumple zone absorbs the force of an impact, reducing the chance that passengers get injured.
d)
The crumple zone transfers the force of an impact from the car to the object it hits, reducing the chance that passengers will get injured.
9.
Which statement best explains why the temperature leveled off in section 2 of the graph?
a)
Alex turned off the hot plate so the water did not get any warmer
b)
The water reached the boiling point, so the temperature no longer increased.
c)
An experimental error caused the graph to level off, because the water temperature should keep increasing over time.
d)
Cold water heats faster than warm water, so once the cold water was room temperature, it took more than 10 minutes to make it hot
10.
What was the rancher’s average velocity? (V=d/t)

b)
0.9 km/h North
c)
2.6 km/h North
d)
3.0 km/h North

the genotype in the mother’s egg
b)
the genotype that only the girls will inherit
c)
the genotype that any of the children could inherit
d)
the genotype that exactly ¼ of the children will inherit
12.
Alice needed to design a science project. She decided that she wanted to focus her project on how an earthworm’s behavior helps it survive. Before designing her experiment, Alice went to the library to learn more about earthworms. Which of the following resources would provide the best information for her to use?
a)
poems and fictional stories about earthworms
b)
non-fiction books and science websites on earthworm adaptations
c)
science websites and magazine articles about how earthworms fertilize soil
d)
personal websites and interviews with friends about their experiences with earthworms
13.
Alice wrote down four ideas about earthworm behavior that she wanted to test. Which idea can be tested experimentally?
a)
Earthworms like the taste of dirt better than sand.
b)
Earthworms are happier in black dirt than red dirt.
c)
Earthworms exist to decompose decaying materials.
d)
Earthworms will move away from direct light sources.
14.
Alice conducted a controlled experiment and tested a single variable. She used one earthworm for her experiment and conducted the experiment once. She typed her conclusion and glued it to her science project poster. The next day, Alice was surprised to find out that she received a low grade on her conclusion. What could Alice do differently to increase her grade on her conclusion?
a)
test more variables in her experiment
b)
print her conclusion bigger and in brighter colors
c)
collect more data by repeating the experiment or using more worms
d)
copy information on earthworm behavior from the resource materials she used
100 %
