  1. What is Science?

  2. Warm-Up • What does the word “science” mean to you? Answer this question on a sheet of paper. It doesn’t have to be complete sentences, words or phrases are fine. You have 1 minute • Turn to a partner and discuss your answers. You have 2 minutes. • Class discussion of responses.

  3. What is Science? The goal of science is to investigate and understand nature, to explain events in nature, and to use those explanations to make useful predictions

  4. What is Biology? • Bio= life • Ology= the study of • Biology: seeks to understand the living world

  5. What is Life? • How do we define life? • Sometimes life can be hard to describe….

  6. 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 trail, 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 slow 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."

  7. What is Life? • All living things: • Are made of cells (1 or more) • Reproduce (sexually or asexually) • Have a universal genetic code (passing on of traits) • Grow and develop • Maintain a stable internal environment • homeostasis • Respond to the environment • What are some examples? • Obtain and use materials and energy • Take in food • Expel waste • Other examples? • As a group, change over time • Adaptation and evolution

  8. What are the Branches of Biology? • Ecology • Anatomy • Zoology • Taxonomy • Botany • Cytology • Bacteriology • Entomology • Herpetology • Histology • Ichthyology • Mycology • Ornithology • Phycology • Embryology • Genetics • Paleontology • Parasitology • Pathology • Physiology
