Experimental Design #1: A scientist wants to test their hypothesis that if they shine light into a fish tank for one week, then the fish will gain weight. The scientist sets up two identical tanks with fish of the same age, size and species, and fed them the same amount of food. The light was shined into one tank for one week. Since one fish was looking a little sad, the scientist gave that fish an extra serving of food to cheer up. Which response explains why the Experiment Design #1 is not valid:
a)
Controlled experiments can only change or test one independent variable at a time.
b)
Dependent variables are not used in controlled experiments.
c)
Control groups will always have sad participants.
d)
None of these
9.
Two types of data that can be collected and analyzed are

Draw conclusions
b)
Make a graph
c)
Form a hypothesis
d)
Observe and make inferences
11.

b)
Store the results in a safe area.
c)
Report results.
d)
None of these
12.
Experimental Design #2: A teacher thinks a special scent pumped through the air conditioning vent into the classroom will make the students perform better on tests. The teacher pumps the special scent into the Period A class of 30 students and gives a test. The teacher gives the same test to the Period B class of 30 students, but does not pump the special scent in to the class. The Period A class reports a very relaxed feeling during the test and they score 8% better on the test than the Period B class. What is the teacher’s hypothesis in Experimental Design #2?
a)
If a special scent is pumped through the air conditioning vent into the classroom, the Period A class will be relaxed.
b)
If a special scent is pumped through the air conditioning vent into the classroom, only the Period B class will perform better.
c)
If a special scent is pumped through the air conditioning vent into the classroom, then students perform better on tests.
d)
None of these
