Method, the Scientific Method
The study of the natural world
What is science?
A testable idea or explanation that leads to a scientific investigation.
What is a hypothesis?
What percentages in a circle graph must add up to.
What is 100%.
The summary of what you have learned from an experiment.
What is a conclusion?
An organized procedure to study something under controlled conditions.
What is an experiment?
The variable that is deliberately manipulated in an experiment.
What is independent variable?
The type of graph is used when showing how each group of data relates to all of the data.
What is a circle graph/pie chart?
The independent variable in the following:
What effect does the amount of light have on plant growth?
What is amount of light?
The process of obtaining information by using the senses.
What is an observation?
The factor that changes as a result of manipulation of one or more independent variables.
What is dependent variable?
The type of graph used to display and compare data in a number of categories.
What is a bar graph?
The dependent variable in the following:
If plants are watered, then growth height will increase.
What is growth height?
The two types of evidence that scientists gather.
What are quantitative observations and qualitative observations?
Facts, figures, and other evidence scientists gather when they conduct an investigation
What is data?
The type of graph used to show continuous change over time.
What is a line graph?
A farmer wants to test a new fertilizer to increase the fruit yields. He sprays garden A with the fertilizer that he has used for years and garden B with the new fertilizer for 2 months. Garden B’s plants have wilted and are not producing fruit while garden A’s fruit production is the same as years prior.
Which is the control?
What is garden A?
All the measurements and data scientists gather in support of a scientific explanation
What is empirical evidence?
The difference between repetition and replication.
What is:
Repetition occurs when an activity is repeated by the same person.
Replication occurs when an activity is repeated by a different person.
Where independent and dependent variables are located on a graph
What is independent variable on the x axis and the dependent variable on the y axis?

Independent Variable ________________________________________
Dependent Variable __________________________________________
What is
