How to Graph our Temperature Data1. Give it a title2. Add time on the bottom3. Labels4. Plot your points

• Mark each data point with a pencil x

• Once you have all the data points check they make sense

• Marker the data points• Connect the data points

using a ruler (pencil 1st)• Look at your graph and

answer the questions as a group.
