Graphical Analysis

Purpose

• The purpose of this activity is for students to learn to collect and graph data.

Materials

• Graphing paper
• Watch w/ a second hand
• “Fat” vest
• Pencil
• Ruler
• Thermometer
• Steps

Procedure

• Measure resting pulse and temperature.
• Then step on steps for two minutes, then measure pulse and temperature.
• Measure pulse and temperature until both are back to the resting rate. Be sure to note the amount of time it takes to return to normal.
• Then put on the “fat” vest.
• After putting on the “fat” vest, step on the steps for two minutes, then measure pulse and temperature.
• Measure pulse and temperature until both are back to the original resting rate. Be sure to note the amount of time it takes to return to normal.
• Collect data and make a graph comparing normal pulse and temperature, pulse and temperature after exercise, and pulse and temperature after exercise wearing the “fat” vest. 
• Also graph the recovery time after each exercise.

Conclusion

• Write a paragraph describing what happens to the body when there is excess fat in the body.
• Also turn in graphs.
