Creating a Paper Graph

Line Graph for Number of Seeds Germinated

You will need a large poster board or butcher paper, thickline markers, a meterstick or ruler, and a pencil with an eraser. Do the outline in pencil to make sure you get straight lines and have enough columns and rows. When the lines are right, go over them with thick line markers; black is best when constructing graphs and charts. Enter the numbers from the bottom to the top and the days from left to right.

The number of seeds that germinated go in the first column and continue until you get to the highest number of seeds that germinated in one observation. The Days go in the bottom row and continue until you have all the days for which you recorded information.

When you have the graph drawn, you can use pencil/pen marks or stickers to show how many seeds germinated that day. See the example below:

You can use one graph for each temperature and label them "Cool Location" and "Warm Location" or use one graph for both by using differently colored ink or stickers to show the number of seeds. For example, you could use blue to show the cool location and red to show the warm location numbers. Make sure your graph has a legend to clearly show which data belongs to which location. Also include your written description in your display.
