Shivering Isn't Enough: Heat Conservation In Homeotherms

Extensions

In this investigation we learned how the amount of insulation and the shape of an animal affect heat loss. It would be interesting to combine both features to see how effective these two features combine together in reducing heat loss.

The investigation will contain the following components:

1. Hypothesis
2. General Experimental Design
3. Materials
4. Safety Considerations
5. Procedure
6. Results
7. Analysis of Data
8. Conclusion

Steps 1-5 must be done ahead of time. Your teacher will assign you to submit your proposal ahead of time, correct it and then allow you to carry out your experiment.

Hypothesis

State your hypothesis in an if....then...format. The hypothesis is an "educated guess" so state why you expect the results which you have predicted. State the hypothesis in a form that includes some specifics. If you do, the hypothesis should guide you through the general design of your experiment.

General Experimental Design

What is your independent variable? How will you set up your controls to insure that you have one and only one independent variable? What is your dependent variable and how will you measure it?

Materials

Make a list of all materials which you will need to conduct your experiment. This takes careful, careful planning.

Safety Considerations

Are you working with chemicals, acids, bases? Are you heating any solutions? How will you protect you and your classmates during your experiment?

Procedure

Determine a reasonable, logical order for carrying out your experiment. Write out a step by step procedure. Include all details.

Results

Prepare a data sheet with tables and a set of axes for a graph. Be sure to enter all data, including any unexpected observations.

Analysis of Data

Determine what manipulations of data will have to be carried out to make an analysis of your results most meaningful. Would a graph make it easier to analyze your results?

Conclusion

What do you conclude based on the analysis of data? Does the data support or refute your hypothesis? Explain
