Factors that can change in an experiment
variable
14
An observation A scientist sees a plant growing in the shade
at the base of a tree. This is an example of: An observation
15
A hypothesis A scientist writes:
The plant, Plantas greenus, grows best in the shade. This is an example of: A hypothesis
16
variables constants The amount of water, soil, and temperature
are examples of: variables constants
17
The independent variable
The amount of sunlight is an example of The independent variable
18
A conclusion A scientist writes:
Plantas greenus grows more when grown in the shade than when grown in partial sun or direct sun. This is an example of: A conclusion
20
Constants those variables that are kept the same
Ex: Each plant gets the same amount of water, sunlight, soil
21
Control: item or group that does not receive treatment
item or group used for comparison Ex: plant that gets no plant food or the original fish food
22
Independent variable:
Variable that is changed in the experiment. The treatment being given What is being tested, investigated Ex: the plant food the different brands of fish food
23
Dependent variable: the variable being measured in an experiment.
Ex: the height of the plants the weight of the mice
