Introduction

Over the past 50+ years, the United States has made great progress in educating the public about the dangers of smoking and even second-hand cigarette smoke. The activities in this lesson will help you investigate the effect of environmental tobacco smoke on human lung development, making it clear how normal body functioning is impaired by environmental toxicants.


Exploration

Go to Toxicology Problem Set and answer the 11 questions posed. These are the same questions that you answered in the Toxicology Problem Set student sheet. As you go through the online version, correct your answers and write the correct answers in the appropriate column of the student sheet.

As you did with those questions, go through the online version, correct your answers, and write the correct answers in the appropriate column of the student sheet. If you are not sure of an answer, click on the Tutorial button to find the information you need to answer the questions. Be sure to also explain your answers in the space provided.

Go to Environmental Tobacco Smoke and Lung Development Activity and do the activity found there. You should work through the four sections in the following order:

  • Hypothesis
  • Methods
  • Data Collection
  • Results and Interpretation

As you work through the online activity, answer the questions on the Environmental Tobacco Smoke and Lung Development activity sheet that your teacher has given you. Be prepared to discuss your answers with the class.


Knowledge Check

Now you have developed an understanding of the principles of toxicology and the research that is conducted in examining the health effects of environmental pollutants, such as second-hand smoke. Use what you have learned to answer these questions:

  1. Besides second-hand smoke, what are some everyday environmental pollutants that can affect our health?
  2. Do you think that we experience chronic or acute exposures to these toxicants? Explain.
  3. What are some diseases or adverse health effects that can result from exposure to these types of toxicants?
  4. Many of these symptoms can be caused by a lot of different things, including genetic diseases. How would a doctor be able to determine if the patient’s symptoms are related to exposure to an environmental toxicant?
