2.
Mixture A contains sugar and water. Mixture B contains lemon juice and water. What does Mixture A have in common with Mixture B?
a)
Both mixtures are solutions in which water has dissolved in a substance.
b)
Both mixtures will taste sweet.
c)
Both mixtures are solutions in which the sugar and the lemon juice have dissolved in water.
d)
The mixtures do not have anything in common.
3.
Mixture A contains sand and water. Mixture B contains rocks and sand. How are mixtures A and B similar or different?
a)
Mixture A is a solution and Mixture B is not.
b)
Both mixtures are solutions.
c)
Neither mixture is a solution

4.
a)
The electrical circuit is working.
b)
The electrical circuit is open.
c)
The electrical circuit is complete.
d)
The electrical circuit is closed.
5.
Students created an electromagnet using copper wire wrapped around a nail and the free ends of the wire attached to the positive and negative poles of a battery. The students knew it was successful because they were able to pick up many paperclips from the table. If the students remove the wire from the negative pole of the battery, what would be most likely result?
a)
Nothing would happen.
b)
It would drop the paper clips.
c)
An electrical shock would occur.
d)
It would pick up more paper clips.
6.
During a discovery investigation, each student group was given the following items: 2 copper wires, tape, a small Christmas tree light bulb, and a "D" battery. The teacher tells them to create a closed electrical circuit. How will the students know if they are successful?
a)
The students will see the light glow.
b)
The students will receive an electrical shock
c)
The students do not have enough material to complete the task.
d)
None of the above statements are correct.
7.
Electromagnets are a type of magnet that can be turned on or off by passing an electrical current through a wire wrapped around an iron object such as a nail. A student wants to conduct an experiment on how the number of coils of copper wire wrapped around a nail will affect the strength of the nail's electromagnetic field. The data collected is listed in the table above. Based on the above information and data table, how does the number of coils of copper wire wrapped around a nail affect the strength of an electromagnetic field?
a)
The strength of the electromagnetic field decreases as more coils of wire are wrapped around the nail.
b)
The strength of the electromagnetic field increases as more coils of wire are wrapped around the nail.
c)
The strength of the electromagnetic field is not affected by the number of coils are wrapped around the nail.
d)
The number of paperclips picked up by the electromagnet increases by 7 for each extra coil of wire wrapped around the nail.
8.
A student tried to create an electrical circuit. He connects a wire to post A on the light fixture and the positive post of the battery as shown in the picture above. What other steps does the student need to complete to create an electrical circuit?
a)
Add a wire to post B on the light fixture and connect it to the positive post of the battery
b)
Add a wire to post A on the light fixture and connect it to the positive post of the battery
c)
Add a wire to post B on the light fixture and connect it to the negative post of the battery
d)
Add a wire to post A on the light fixture and connect it to the negative post of the battery
9.
Observe the image above. A teacher built an electromagnet using a battery, a copper wire, and an iron nail. The teacher asks the class to make a change to the electromagnet in order to collect more paper clips.What is one change that can be done to the electromagnet to collect more paper clips?
a)
Wrap the wire more times around the nail
b)
Flip the battery the opposite direction
c)
Use a longer copper wire
d)
Plug in the electromagnet
10.
In the diagram below, which wires complete the circuit that makes the bell ring?
a)
Wires 1, 2, and 3
b)
Wires 1, 2, 3, and 4
c)
Wires 2, 3, and 4
d)
Wires 2, 3, 4, and 5
11.
During an investigation of soil samples, funnels are placed on top of glass beakers. Each funnel is then filled with different soil samples. Then, 100 mL of water is poured into each soil sample.The purpose of this investigation is to determine –
a)
how much water is retained by each soil sample
b)
the mass of each soil sample
c)
the relative density of each soil sample
d)
which soil is the darkest color
12.
Students conducted an investigation on four different soil samples. They chose to plant black beans in the different soil types. Their data is recorded in the table.Based on the information provided, which soil sample is most likely the best choice for growing black beans?
a)
Soil 1
b)
Soil 2
c)
Soil 3
d)
Soil 4
13.

a)
Cactus
b)
Ferns
c)
Grass
d)
