Nature of Science 1.1 SSA Review Quizizz

Christopher is following these steps during a lab.

Procedure:

1. 1. Fill 4 cups halfway with water
   2. Add 10 drops of both blue and red food coloring to each cup to make purple water

2. 3. Label the cups with: 10 min, 20 min, 30 min, and 40 min

3. 4. Place 1 stalk of celery in to each cup for the amount of time on each cup

4. 5. Record your observations every 5 minutes

5. 
   Which of the following statements is he most likely testing?

• If blue and red food coloring are added to water in equal amounts, then the water will turn purple
  

• If there are 60 seconds in a minute, then 40 minutes will take 2,400 seconds
  

• If the celery absorbs the water through its stem, then the plant will change color
  

• If the celery absorbs purple water, then it will taste better
  

A student is setting up an experiment with several plants. Her teacher recommends that she set up a control plant.
Why should the student have a control group in her experiment?

• To make sure the plant would have grown under normal circumstances
  

• To help the student become a better plant caretaker 
  

• To give the student more work to complete
  

• To create a competition between the plants to encourage growth

After each trial in an investigation, a student changes the mass of an object by adding additional weight. The student then places the object at the top of a ramp that is 25 centimeters in height and measures the distance the object travels down the ramp. Why is the distance the object travels different in each trial??

• The force applied to the object at the top of the ramp changes.​
  

• The height of the ramp changes.​
  

• The mass of the object travelling down the ramp changes.
  

• The material the ramp is made of changes.​

• Drop the same ball from different heights on to the same surface.​
  

• Drop the same ball from the same height on to different surfaces.
  

• Drop the same ball from different heights on to different surfaces.
  

A student measures the distance a toy car travels down a ramp. After each trial, the student adds an additional textbook to increase the height of the ramp by 5 centimeters.? Which question is the student most likely trying to answer with this scientific investigation?

• How does the mass of an object affect the distance it will travel on a ramp?​
  

• What causes an object to travel down a ramp?​
  

• How does the height of the ramp affect the speed of an object?​

Lori wants to see if dark colored soda loses its carbonation faster than clear colored soda. The steps she followed in her experiment are below.
1.  Get several types of dark and clear sodas.
2.  Pour equal amounts of soda in similar glasses.
3.  Recycle all of the bottles that the soda came from
4.  Leave glasses on the counter in an open environment.
5.  Each hour come back and record carbonation results.

Which step in Lori's experiment was not needed?

• Leave glasses on the counter in an open environment.
  

• Each hour come back and record carbonation results.
  

• Recycle all of the bottles that the soda came from
  

• Get several types of dark and clear sodas.
  

• Pour equal amounts of soda in similar glasses.
  

The picture above shows the Earth's layers. Why might a student use a model to study the Earth's layers?

• People, animals and plants are all on the surface.
  

• The Earth's layers are unknown.
  

• The Earth's layers are too large to study directly.
  

• The Earth's layers are too small to study.
