There are a lot of different objects around the room for students to measure. If you cannot think of any, just use a sheet of paper cut to the length you want the students to measure. Assign students a partner and tell them whether they will be taking readings on odd or even days. Discuss how much time they will have to complete their readings. Remind students to include the proper units with their readings.
Students are to answer the questions on the questionnaire and complete the graphing exercises.
Teachers may have students do any type of readings they prefer. Weather readings are always a good suggestion. Students could keep a daily journal of the weather conditions outside. Students can make a double line graph using the day number vs the inside and outside daily temperatures. This will help to show students that the inside temperature usually remains constant while the outside temperature is constantly changing.
