  1. Agony and Ecstasy Norris Armstrong University of Georgia-Athens

  2. Lesson Objectives • Develop and use a model based on evidence to illustrate the relationships between systems or components of a system • Explain how the disruption to Lena Bedolla’s system impacted her health

  3. Entry Task: Quick Write What is the purpose of the nucleus? Name 2 organelles that are found in plant cells but not animal cells? What is the purpose of the cell membrane?

  4. Questions to Think About • Why can’t I water plants with salt water? • Why do slugs die when I put salt on them? • Why was salt so important to ancient cultures? • Why do my fingers wrinkle after a long time in the water? • How does cholera kill people?

  5. You are a new doctor or nurse at the local hospital. It is Monday morning and you are checking some patient charts when a man and a woman rushed through the doors, carrying a second woman. “Help! Can you help us?” one called. You and a nurse rushed them into an exam room. “What happened?” You asked while examining the patient. “We don’t know!” the female student sobbed. “Lena started feeling sick at a party last night. She came home and went to sleep, but then couldn’t wake up this morning. She was acting so weird we decided to bring her here.” You carefully observe the woman lying on the table. She was rolling her head and clearly seemed confused. However, there were no obvious signs of trauma. “Has Lena taken any drugs recently?” The two students hesitated and looked at each other. Finally one of them nodded. “I think she took some Ecstasy last night.”

  6. What is wrong with Lena? • What kinds of questions are you going to ask to find out more about Lena? • TIME IS OF THE ESSENCE!

  7. You think for a moment. Ecstasy had been fairly popular on the party scene for several years now. You had seen people on the drug become somewhat confused, but not delirious. Maybe Lena was having an adverse reaction to the drug. It was a start. To be safe, you ordered a series of blood tests.

  8. Ecstasy (MDMA) Fact Sheet • MDMA (3,4 methylenedioxymethamphetamine) is a synthetic, psychoactive drug chemically similar to the stimulant methamphetamine and the hallucinogen mescaline. MDMA acts as both a stimulant and psychedelic. It produces an energizing effect, distorts both physical and cognitive sensations, and may impair memory. • MDMA affects a neuron’s ability to use the chemical serotonin. Serotonin plays an important role in regulating mood, aggression, sexual activity, sleep, and sensitivity to pain. Research in animals indicates that MDMA is a neurotoxin. MDMA is potentially harmful to health and, on rare occasions, may be lethal.

  9. Ideas why Lena is ill? MDMA may affect: • Blood pressure • Pulse rate • Body temperature • Hyperthermia • Hypothermia • Water Balance • Dehydration • Excess water • Blood sugar level

  10. Blood Test Results

  11. Initial Model • Work with your team/partner to record your initial ideas about what is happening to Lena. • Use both pictures and words and work on both sides of the initial model.

  12. Exit Task: Quick Write • What questions do you have about Lena Bedolla’s situation? • What else do you think you need to know more about in order to explain Ms. Bedolla’s illness?
