1. Warm-Up On page 5 at the top, please answer these questions:
If the principal or vice-principal were to walk into my classroom, explain:
Two things they would See!
Two things they would Hear!

2. Learning Target
Learn, discuss, and reflect about the Nature of Science and construct a science project.

3. What is Science?

4. Avenues of thinking and knowing
religion (based on faith)
philosophy (based on logical reasoning)
literature (interpretation of the world expressed through verbal communication)
art (interpretation of the world expressed through production or arrangement of colors, forms, movements, sounds or other elements)
Science!

5. (or what does a scientist do?)
WHAT IS SCIENCE?*
(or what does a scientist do?)
observing (collecting data)
formulating hypotheses
predicting
conducting experiments
interpreting data (drawing conclusions)
developing theories
applying knowledge to solve problems

6. Science is a Process
It has taken many centuries to arrive at what we know today.
Examples: in the past people thought the world was flat (except some Vikings and Greeks)
Greeks and others thought the earth was the center of the solar system and that the sun revolved around the earth.
Early scientists said that the only elements were Earth, water, fire, and air.

7. Science Continued...
Myth and superstition drove science for hundreds of years.
This occurred from lack of knowledge and understanding of the world.

8. *Myth and superstition were then replaced by...
Fact and Knowledge!!

9. What inferences do you draw from observing the following?
your classmate wears a UW sweatshirt
a damaged car parked at the curb
broken tree limb in a neighbor’s yard
Inference: interpretation based on
indirect evidence

10. Observation vs. Inference*
Observation = What you see, hear, feel, etc. (using your 5 senses!)
> ex.) “The sky is cloudy”
Inference = Conclusions that you make based on your observations
> ex.) “It’s going to rain today”

11. Hypotheses Science proceeds by testing hypotheses.
Hypotheses are tentative explanations of observed phenomena
Purpose of scientific experimentation is to test hypotheses.

12. Compare a hypothesis with a theory*
hypothesis: tentative explanation of observed phenomenon
theory: explanation which is supported by many experimental events and evidence

13. How does science influence you everyday?
cars
televisions
food/water
your home
electricity/computers
clothes
hygiene/health
ecosystems/the environment
etc.

14. Concerns in Science Just because we can, does it mean we should?
Science is full of ethics, and we must remember our responsibility to our world.

15. Science is Changing Constantly
Technology has allowed science to grow rapidly and provide us with products to live our lives.
This has caused other problems around the world (pollution, etc.).
What will the future bring?

16. Science as we know it today *
Driven by fact and knowledge.
Still lots of trial and error.
Follows the “scientific method” and scientific inquiry.
Many good and bad outcomes have come from science.

17. Bad Outcomes of Science
Weapons of mass destruction
Biological warfare/epidemics
pollution, greenhouse effect, ozone hole, habitat destruction, extinction of species, loss of biodiversity, etc.

18. Good Outcomes of Science
Foundation of understanding for our world/knowledge
Cures for deadly diseases/health
food preservation
housing/amenities
entertainment
technology!

19. Science Branches
physical science: the study of matter and energy through physics and chemistry
earth science: geology, astronomy, meteorology, oceanography
biology/life sciences: studies living things, both animals and plants, etc. (botany, zoology, microbiology, etc.)

20. Scientific Method* State the problem Gather information on the problem
Form a hypothesis
Perform experiments to test the hypothesis
Record and analyze data
State a conclusion (a statement based on the results of the experiment)
Repeat the work

21. Vocabulary Review *
hypothesis-proposed solution to a scientific problem
variable-factor being tested in an experiment
control-standard with which to compare results
data-recorded observations and measurements

22. Science in the Future
It is now up to us to make educated choices and decisions in favor of the environment and our planet.
This will ensure a healthy future for all generations.

23. What are your ideas about science?
This class will help you form
your ideas and learn a lot
more about science!
