Lesson 1 - What is Science? Objectives: Discuss the meaning and value of science. List some parts of your lifestyle that may be affected by advances in biology.
A. Science and Biology science - investigates and observes the natural world and explains events in the natural world - produces reliable knowledge of the natural, physical world
Values of Science: - skepticism - Prove it to me! - physical evidence - Don’t believe it just because someone else told you to. The “authority” is not necessarily correct. Science progressed because scientists often rejected authority and searched for answers to questions that some people didn’t want answered. - connections - between facts and what they mean ----> theories!
Biology - the science that investigates living things and their interactions with the surrounding world
B. Biology and Medicine - early 1900s - the top 3 killers were infectious diseases
- influenza, tuberculosis, pneumonia
- in 1918, 22 million people died of the flu **What two major advances in medicine changed this? **What are the three most common killers in the US today?
- in recent years, a new technology has emerged that may drastically change your future --> genetic engineering
- gene transfer therapy - copies of normal genes or corrective genes are transferred to patients with an abnormal gene --> first hope for cures for genetic disorders such as CF and MD
C. Biology and the Environment - in year 1 AD, the world contained about 300 million people -when you were born, the world contained about 4 billion people - in the year 2000, the world contained over 6 billion people - by the year 2050, the world will contain over 9 billion people - overpopulation creates great stress on our environment:
- energy, resources, waste disposal, food, species, etc.
- biologists are exploring ways to relieve stress on our environment:
- increase food production
- alternatives to pesticides
- pollution cleanup
- maintain biodiversity “We do not inherit the world from our parents... we borrow it from our children.”
Some Questions to Discuss: 1. What makes science different and different from what? 2. Is there a scientific method? And, if so, a method to do what? 3. What does the general public think about science? What do YOU think about science? 4. Why does our society support science? 5. Could we do without science?
