The Martian and the Car
Marty Martian was sent to Earth by the Martian government to find life. While on Earth, Marty captured a car and brought it back to Mars. He thought he'd found a good example of life on Earth. The Martian government does not believe that the car Marty brought back is alive. Marty must stand trial for failing to perform his Martian duties.
At the trial, Marty spoke in his defense. "I first saw these life forms rolling along roads in great numbers. They were giving off thick clouds of poisonous waste as they moved. They seemed to exhibit herding behavior, as many of the cars moved in the same direction. They appeared to have a great deal of energy, some of them moved faster than 60 kilometers per hour. When one of these life forms stopped or slowed down, the others behind it responded. They slowed down and gave off a reddish light from the back, and sometimes they would make honking noises. I observed that they would stop to feed on a liquid substance."
Take the part of Marty's defense attorney and make a good case for the car's being alive. Then be the prosecutor and show that the car is a nonliving thing. List as many reasons as you can. Finally, write the opening statements for both the defense attorney and the prosecutor.

Part III – Finding a Treatment
Julie and her friends met for dinner later that week. Their rashes were no longer itching uncontrollably and they were laughing about their troubles. All of them had been to the local stores to find lotions to relieve their symptoms. None worked great since the rash and blisters did not go away, but a few treatments dried up the blisters and stopped some of the itching.
One particular treatment that Julie kept seeing on the Internet was related to an herbal remedy containing jewelweed, a native plant (Figure 3). A natural and organic approach to control the symptoms seemed appealing. It was also one that her mother told her she had used at nature camp.
“Just rub the leaves of jewelweed where you touched the poison ivy,” the camp counselors had recommended, “then you will not get the rash. It is easy to find since it grows in the same places as poison ivy. This remedy was passed down from the first Americans, the Indians.”
Julie told herself that she had better learn to recognize the plant because she did not plan on staying in her room for the rest of her life!
Your job is to use the scientific method to plan an experiment to determine if jewelweed is an effective treatment. First, develop a hypothesis that includes a justification and prediction. Second, plan the experiment. These questions will help you:
(a) How will poison ivy be applied?
(b) What part of jewelweed should be used for treatment—the flowers, the leaves, the stems, all parts of the
plant?
(c) How will jewelweed be applied?
(d) Who will be tested?
(e) How will they be tested?
(f) What are the controls?
(g) What variables must be considered?
(h) What type data should be collected?
(i) How will those results be analyzed?
