A group of students wanted to find out what affect a light or dark habitat would have on
milk weed bug behavior. They set up a terrarium so there were three different light conditions; full
light, filtered light, and a dark area. They put dry paper towels in the full light area, moist paper
towels in the filtered light area, and very wet paper towels in the dark area. Then they put 8 milk
weed bugs in the terrarium and left them for 2 hours. When they returned, all of the milk weed
bugs were in the full light area. The students concluded that the affect of a light or dark habitat
was that the milk weed bugs prefer the light. This conclusion may be incorrect because:
a.
b.
c.
d.
Students had more than one manipulated variable
Students had more than one controlled variable
Students had more than one responding variable
Students had no variables in this investigation

A group of students wanted to find out what affect a light or dark habitat would have on
milk weed bug behavior. They set up a terrarium so there were three different light conditions; full
light, filtered light, and a dark area. They put moist paper towels in the entire terrarium. Then they
put 8 milk weed bugs in the terrarium and left them for 2 hours. When they returned, all of the
beetles were in the dark area. They conducted the same experiment 3 days in a row and got the
same results. The students concluded that the affect of a light or dark habitat was that milk weed
bugs prefer the dark.
Identify the following:
28.
the manipulated variable
a. Amount of light
b. Length of time in the terrarium
c. Filtered light
d. Milk weed bugs location at the end of the experiment
29.
the responding variable
a. Amount of light
b. Length of time in the terrarium
c. Filtered light
d. Milk weed bugs location at the end of the experiment
30.
a controlled variable
a. Amount of light
b. Length of time in the terrarium
c. Filtered light
d. Milk weed bugs location at the end of the experiment
