Graphing In Science2013

Objective• SWBAT (1) Communicate data through tables and

graphs.(2) Create appropriate graphs based on data.

What is the purpose of a data table?• Present information in a usable format

What is the point of a graph?• Make information more accessible• Make information more clear

What are the parts of a graph?

Dependent vs. Independent Variables• Dependent Variable- depends on the other

variable to occur• Growth of a plant depends on days or daylight• Deer population depends on the time of year

• Independent Variable- Occurs with or without the dependent variable• Ex-Time• Also known as the• controlled variable• manipulated variable

Types of Graphs/Charts• Bar-Used to compare individual information

• Ex- average height of boys vs. girls• Line-Used to compare things over a period of

time• Average monthly growth of boys vs. girls over a year

• Pie-(Not used in science) Used for percentages
