Scientific Method and Graphs

All scientific investigations begin with:

• Asking a question or a problem

• Conducting an experiment

• Forming a hypothesis

The variable that is deliberately changed in an experiment is called the:

• Control

• Independent

• Dependent

How does the length of a pendulum affect the number of swings?  In this investigative question, what is the INDEPENDENT variable?

• Length of the string

• Number of swings

• Time of the swing

How does the type of liquid drops put on a penny affect the number of drops it will hold?  In this investigative question, what is the DEPENDENT variable?

• Type of liquid

• Number of drops on a penny

• Temperature of the liquid

How does the type of liquid drops put on a penny affect the number of drops it will hold?  In this investigative question, what is the INDEPENDENT variable?

• Type of liquid

• Number of drops on a penny

• Temperature of the liquid

A hypothesis is written as  __________________

• a question

• an if and then statement

• an opinion statement

A bar graph:

• Good for comparing the relationship between two sets of quantitative data

• Is good for comparing quantitative data of experimental tests or how one variable affects another

• Is good for showing percentages of a whole

• Is good for tracking changes over time

A pie graph:

• Good for comparing the relationship between two sets of quantitative data

• Is good for comparing quantitative data of experimental tests or how one variable affects another

• Is good for showing percentages of a whole

• Is good for tracking changes over time
