a. Write a hypothesis for Krissy.
A hypothesis is an educated explanation for a situation that can be tested. A hypothesis is usually written as an "if..., then..." statement. Therefore, a plausible hypothesis for Krissy would be: "If Skin-So-Soft is present, then there will not be as many mosquitos present".
b. What was the control group?
The control group is the group in a scientific experiment that does not receive the change that is undergoing observation/...

b. What was the control group?
The control group is the group in a scientific experiment that does not receive the change that is undergoing observation/ experimentation. The control group serves as a benchmark to which the other tested groups are referred. Therefore, the control group for Krissy’s experiment would be the container that contained water.
c. What was the independent variable?
The independent variable is the variable that the scientist changes. In this case, it would be the liquid to which the mosquitos are exposed.
d. What was the dependent variable?
The dependent variable is the variable that the scientist is measuring. In this case, the dependent variable would be the number of mosquitos.
e. What should Krissy conclude?
Conclusions summarize how the data from an experiment either supports or rejects the hypothesis. Data from the experiment should be included within a conclusion.
Krissy should conclude that when Skin-So-Soft is present, then there are not as many mosquitos present. Her hypothesis is supported by the fact that rag that contained Skin-So-Soft had 10 mosquitos near it while 50 mosquitos were over the rag that contained water.
