**Objectives:**
This lesson is appropriate for students in middle and junior high.
The students will be able to work cooperatively in small groups.
The students will be able to convert centimeters to millimeters, meters to
centimeters, meters to millimeters.
The students will be able to graph the width and the height of their tower.
The students will be able to tell the teacher if there is a mathematical
relationship between the height and the width of the base.
**Materials Needed:**
Straw
Paper Clips
Meter Sticks
Graph Paper
Worksheet of instructions
**Strategy:**
Give each small group a minimum of 30 straws and a box of regular size paper
clips.
Using the materials they are to construct a structure in fifteen minutes.
Measure the height of all the structures in millimeters, that are standing
without assistance.
Convert measurements to centimeters and meters.
Measure the width of the base at its widest point in millimeters.
Convert measurements to centimeters and meters.
Enter data on graph provided by the teacher.
After observing the data make a judgement if there is a relationship between
the width of the base and the height obtained.
