Period 8 October 26, 2010

Today, like any other day, we started off with marking the spots on our grids, on our petri dishes. After finishing marking our data we started to work on writing notes for our graphs. We had already started taking notes yesterday. These are those notes and the ones that we added on today! While making a line graph include these items:

• Labels, title, and units.
• Scale-even intervals-don't need to start at zero ALL the time.
• More than one line can be on the graph (double line graph) use symbols or colors.
• Don't need to number every tick mark.
• Trend Line-line that shows a pattern in the data; shows direction; doesn't need to go through dots; represents the data: also allows us to keep in mind that human error might be a reson for imperfections.
• Dependant variable on y axis and independent variable goes on x axis.

Trand lines dont have to be perfect but they also help!!!!!
