Controlled experiments cannot be performed on liveing things.
Only one variable is tested at a time.
All the variables must be kept the same.
Scientists always use controlled experiments.
A well-tested explanation that unifies a broad range of observations.
Another word for hypothesis.

Time in days
Size of the containers.
Number of flies.
Differnce in time per group.
Number of groups studied.
The flies in group B were healthier than those in Group A.
If Group B were observed for 40 more days, the size of the population will double.
A fly population with more available space will grow larger than a population with less space.
In 40 more days, the sizes of both populations would decrease at the same rate.
The pattern shown in the graph is true onliy for fruit flies.
