Purpose: To investigate the heat absorption and transfer properties of various soils. You will experiment with Earth soils inside and outside. Your results from the outside soil experiment should be compared with data from the Mars Viking Lander 1. You may notice there is not enough information to reach a firm conclusion about the Mars soil measurements. After your Earth soils experiments you will design your own experiment that could be carried on a future Mars mission.

Do this experiment in your classroom under controlled conditions. Heat the soil samples with light bulbs and record the soils' temperatures over time. (This lab is the same as the Outside Soil Test, only done inside the classroom) You will use the Scientific Method to gather information about the possibility of living on Mars.

Hypothesis 1: The changes its temperature more rapidly than soils.
Hypothesis 2: The soil will have a greater temperature change than soils.

Study the variables so that you will be better able to maintain the controlled variables and keep the experiment valid.





Conclusion: Now, compare your results with the initial hypotheses.

The first hypothesis WAS/ WAS NOT supported

The second hypothesis WAS/ WAS NOT supported

Explain how the results of this test support, weaken or otherwise affect the initial hypotheses.

What other information about Martian soil would you like to know?

Design an experiment for future Mars missions that would provide additional information about Martian soil that you think would be helpful:
