Students will analyze data collected by experimenting with the greenhouse effect and report their findings.
This investigation is designed to be completed over the course of several weeks.

Objectives:

Use mathematics to analyze aspects of the greenhouse effect and report your findings.
Mathematical Overview and NCTM Standards:
• Understand patterns, relations, and functions
• Understand meanings of operations and how they relate to one another
• Apply appropriate techniques, tools, and formulas to determine measurements
• Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them
• Select and use appropriate statistical methods to analyze data
• Build new mathematical knowledge through problem solving
• Monitor and reflect on the process of mathematical problem solving
Materials Needed:
• lamp with a 100-watt bulb
• stopwatch
• thermometer
• plastic zipper-style sandwich bag
• ruler
• graph paper
• folder or notebook
Procedure:
In this Investigation, you will use mathematics to analyze aspects of the greenhouse effect and report your findings.  As a scientist commissioned to explore the greenhouse effect, you will conduct two experiments.  The first experiment is a control experiment that will be used to compare data with the second experiment, called the greenhouse experiment.  Both experiments will involve temperature as a function of distance.
• Separate the class into groups of four.
• Recorder collect data
• Measurer sets and measure the distances between the lamp and the thermometer.
• Timer times different aspects of the activity and turns the lamp on and off at the appropriate times.
• Weather person reports temperature reading to the recorder and makes sure that them thermometer is adequately prepared for each aspect of the activity.
• Conduct a control experiment and a greenhouse experiment.
• Record data using a spreadsheet and use graphing tools to model the data.
• Analyze and report this data.  Each member should turn in his or her respective equipment and their own folder.
