What is Science? Science is always evolving! It is a stream of ideas that are constantly being reshaped, added to, subtracted from and built upon. Science is about PREDICTABILITY The science that we know today gives us the ability to predict certain things about the world around us.

How to think like a scientist: 1. Be Curious 2. Be Skeptical 3. Be Flexible These three exercises add up to what is called Critical Thinking, and that’s what scientists do all the time!!

How to act like a scientist: * Critical Thinking is not a guarantee of truth. Scientist use a four step approach when they are trying to find out new information. Observation Hypothesis Experiment Conclusion This is called the scientific method!

Great “Truths” At various times in history, scientist “knew” certain things: 4000 BC: The moon is eaten once each month by a large invisible beast. 1400 A.D.: Diseases are caused by evil spirits that inhabit a body. 1500: Flies develop spontaneously from rotten meat.

Great “Truths” cont: 1600: The brain pumps fluid into the muscles to make them bulge and contract. 1800: Tyrannosaurus Rex walked vertically and dragged its tail. 1850: The planet Mars is covered with canals that only could be made by intelligent life. 1900: The Apatosaurus and Brontosaurus are two different dinosaurs

Great “Truths” 1970: Saturn is the only planet with rings around it. 1980: Eating eggs makes your cholesterol levels rise. 1985: Pandas are bears 1990: Tadpoles eat plant; frogs eat meat. 1995: The Human Genome Project begins and estimates that human chromosomes carry about 100,000 genes.

Great “Truths” 1999: The year 2000 problem (aka Y2K or the millennium bug) was predicted to make some computers unable to handle the date change at the turn of the century. Today, because of research we know that these statements are not true. If time allows, have groups of students look up what we know today for each time period and present to class. Or, teacher can tell what we know today.

What is a Scientist? What words come to mind when you think about a scientist? What does a scientist look like? Create a picture in your mind of what you think a scientist looks like. Have a class discussion of the words that students come up with. Discuss what scientist really are.

Future Scientist: How observant are you? Ask the questions in Rx for Science Literacy that goes along with How observant are you?

Did You or Will You Ever? 1. Drink tap water? 10. Take medication 2. Have a dog? 11. Know anyone with 3. Have a cat? diabetes that needs 4. Fertilize your lawn? to take insulin? 5. Drink milk? 6. Eat a hamburger? 7. Call Poison Control? 8. Receive a vaccination? 9. Take an antibiotic?

Biomedical Research: There isn’t a day that goes by that medical research doesn’t affect our lives! Biomedical Research has resulted in: *Treatments for Heart Disease, Diabetes and Cancer. *Vaccines to protect against diseases like polio, chicken pox and hepatitis. Development of treatments such as Fluoride and Antibiotics Surgical procedures such as Heart Bypass surgery or Transplants.

Careers in the Biosciences: Job opportunities for biological and medical scientist and biological technicians will grow at a faster rate than most occupations in the next decade, according to BEST JOBS for the 21st CENTURY. *Bioscientist * Biomed engineers *Animal Health Technician *Genetic counselors *Lab Technician * Clinical Trials *Medical Technologist * Pharmaceuticals *Statisticians * Computer programmers
