### A scientist plants two rows of corn for experimentation. She puts fertilizer on row 1 but does not put fertilizer on row 2. Both rows receive the same amount of water and light intensity. She checks the growth of the corn over the course of 5 months. What is one controlled variable in this experiment?

• A.

Amount of fertlizer given to experimental group

• B.

Growth of corn

• C.

Type of fertilizer

A. Amount of fertlizer given to experimental group
Explanation
The controlled variable in this experiment is the amount of fertilizer given to the experimental group. This means that the scientist is only changing one factor (the amount of fertilizer) while keeping all other factors constant (same amount of water and light intensity) in order to observe the impact of the fertilizer on the growth of the corn. By controlling this variable, the scientist can accurately determine the effect of the fertilizer on the corn's growth without any other factors influencing the results.

### Which sentence best describes the importance of using a control group?

• A.

When you use a control group you don't need a large sample size.

• B.

When you have a control group you don't have to do any calculations.

• C.

Control groups allow you to compare those recieving the variable and those that are not.

C. Control groups allow you to compare those recieving the variable and those that are not.
Explanation
Control groups are essential in research studies as they provide a basis for comparison between the group that receives the variable being tested and the group that does not. By having a control group, researchers can isolate the effects of the variable and determine its true impact. This comparison helps in drawing accurate conclusions and establishing cause-and-effect relationships.

### Suzy wanted to know if thicker candles burn longer than thinner candles. Her hypothesis was that if she used a thick candle that it would burn for the longest amount of time. She got ten candles that were all the same brand, height, smell, and color. The only difference in the candles was they were all a different size, She lit them at the same time and recorded how long it took for each candle to burn out. What was her independent variable?

• A.

Thickness of the candle

• B.

Length of time the candle burned

• C.

Color of the candle

A. Thickness of the candle
Explanation
The independent variable in this experiment is the thickness of the candle. This is because Suzy is manipulating the thickness of the candles to see if it has an effect on the length of time they burn. The other variables, such as the length of time the candle burns and the color of the candle, are not being manipulated by Suzy and are therefore not independent variables in this experiment.

### Janet wanted to see if the height of a person affected the length of their handspan. She measured three people's heights, and measured their handspans. She found that the taller a person is, the longer their handspan is. What is wrong with her experiment?

• A.

She tested too many variables at once.

• B.

She did not test a large enough sample of people.

• C.

She did not control all of the variables.

B. She did not test a large enough sample of people.
Explanation
The correct answer is that Janet did not test a large enough sample of people. In order to draw accurate conclusions about the relationship between height and handspan, it is important to have a sufficient sample size. Testing only three people may not provide enough data to make a generalization about the entire population. A larger sample size would help to ensure that the results are more representative and reliable.

### Hich of these statements is NOT a good conclusion for the graph shown?

• A.

Big Red blows smaller bubbles than Hubba Bubba.

• B.

All Day Chew blows bubbles almost as large as Hubba Bubba.

• C.

Hubba Bubba is the brand most kids want to chew.

C. Hubba Bubba is the brand most kids want to chew.
Explanation
The graph does not provide any information about which brand of bubble gum most kids want to chew. The graph only compares the sizes of the bubbles blown by different brands of bubble gum. Therefore, the statement "Hubba Bubba is the brand most kids want to chew" is not a good conclusion for the graph.

Rate this question:

• 14.

### Which hypothesis would have been supported by the data from this graph?

• A.

If Stride is chewed, then most kids will like it.

• B.

If Hubba Bubba is chewed, then the flavor will last the longest.

• C.

If Big red is chewed, then it will have the smallest bubble.

C. If Big red is chewed, then it will have the smallest bubble.
Explanation
The graph shows the bubble size for different types of gum. It can be observed that the bubble size for Big Red is consistently smaller compared to the other types of gum. Therefore, the data from the graph supports the hypothesis that if Big Red is chewed, then it will have the smallest bubble.

### What would be a controlled variable in the experiment from this graph?

• A.

Number of times gum is chewed

• B.

Brand of bubble gum

• C.

Size of bubble

A. Number of times gum is chewed
Explanation
In this experiment, the controlled variable would be the number of times gum is chewed. This means that the researchers would keep the brand of bubble gum and the size of the bubble constant throughout the experiment, while only varying the number of times the gum is chewed. By controlling this variable, they can determine the effect of chewing on the size of the bubble.

### Hat would be an independent variable from the experiment with this graph?

• A.

Number of times gum is chewed

• B.

Brand of bubble gum

• C.

Size of bubble

B. Brand of bubble gum
Explanation
The independent variable in this experiment is the brand of bubble gum. This is because the number of times gum is chewed and the size of the bubble are dependent on the brand of bubble gum being used. By changing the brand of bubble gum, we can observe how it affects the number of times gum is chewed and the size of the bubble.

### A ____ group is a group that does not get the variable being tested.

control
Explanation
A control group is a group that does not receive the variable being tested. This group is used as a comparison to the experimental group, which does receive the variable. By having a control group, researchers can compare the results of the experimental group to a baseline and determine if the variable being tested had any effect. The control group helps to ensure that any observed effects are due to the variable being tested and not to other factors.

Rate this question:

### An ____ group is a group that does get the variable that is being tested.

experimental
Explanation
An experimental group is a group that receives the variable that is being tested. In an experiment, the researcher manipulates the independent variable and assigns participants to either the experimental group or the control group. The experimental group is the group that receives the treatment or intervention being tested, while the control group does not receive the variable being tested. By comparing the outcomes of the experimental group to the control group, researchers can determine the effectiveness or impact of the variable being studied.
