Science

Question 1

Independent Variable

Answer 1

the variable that is purposely changed by the experimenter (I-change)

Question 2

Levels of the Independent Variable

Answer 2

the levels of changes that are made to the IV
(ex. different types of water)

Question 3

Dependent Variable (DV)

Answer 3

the variable that may change in response to the changes in the IV, the variable gets measured or observed (ex. plant growth)

Question 4

Title

Answer 4

written with the words capitalized as
“The Effect of the (Fill in the IV) on the (Fill in the DV)

Question 5

Hypothesis

Answer 5

a prediction about the outcome of the experiment; it states the relationship between the independent variable and the dependent variable, written as an “If…, then…” statement. (educated guess)

Question 6

Constants

Answer 6

all factors that remain the same in an experiment

Question 7

Control

Answer 7

the one IV level in an experiment where the independent variable is not applied and no IV is given to this group (not all experiments have a control) (Standard for comparison)

Question 8

Repeated trials

Answer 8

the number of experimental repetitions, objects, or organisms tested at each level of the independent variable

Question 9

Data table

Answer 9

a table that contains the results in your experiment. It contains the levels of the IV, # of repeated trials, results for the DV, and the mathematical average/computation of the results

Question 10

Experimental Error

Answer 10

potential sources of error should be identified in an experiment
Constants not controlled
Small sample size
Not doing repeated trials
