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!

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

What is Science?

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!

(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

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.

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

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

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

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”

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

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

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

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.

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?

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.

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.

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

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.)

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

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

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.

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

“What is Science” Assignment #4, Page 7 1. In the center of your page, write “What is Science?” 2. Answer this question from your perspective. What does it mean to you? (2-3 sentences) 3. Cut and paste 8 “Science” pictures from magazines around the page in a collage format. 4. Write down 8 science words around the page (collage format). 5. At the bottom of the page, explain your project in a couple complete sentences!
