- 7. conclusion
the factor that you change in an experiment is called...
independent or manipulated variable
the factor that chages the result of the independent variable
responding or dependent variable
an experiment in which all factors except for one are kept constant
a statement that describes how a particular variable is to be measured or how a term is to be defined.
the observations and measurements you make in an experiment
a statement that sums up what you have learned from an experiment.
Where do scientists record their measurements and data
used to display data in a number of separate, or distinct, categories
used to show how one variable (responding variable) changes in response to another variable (control)
a graph or chart that shows a category compared to 100%
A question or purpose to guide your activity
problem, question, or objective
The background information to help answer the problem question
an educated guess written as an if. . . then statement
list of items used ot conduct experiment
sequential list of the steps to complete experiment
details about what is observed during the lab using your five senses. recorded in tables, graphs, diagrams
a summary of data collected based on facts, not opinions. an interpretation of the data
An answer to the problem question based on data collected and applied to real life situations. Flaws in experiment are explained.
