Warm-Up l On page 5 at the top, please answer these questions: l 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 l Learn, discuss, and reflect about the Nature of Science and construct a science project.
What is Science?
Avenues of thinking and knowing l religion (based on faith) l philosophy (based on logical reasoning) l literature (interpretation of the world expressed through verbal communication) l art (interpretation of the world expressed through production or arrangement of colors, forms, movements, sounds or other elements) l Science!
WHAT IS SCIENCE?* (or what does a scientist do?) l observing (collecting data) l formulating hypotheses l predicting l conducting experiments l interpreting data (drawing conclusions) l developing theories l applying knowledge to solve problems
Science is a Process l It has taken many centuries to arrive at what we know today. l Examples: in the past people thought the world was flat (except some Vikings and Greeks) l Greeks and others thought the earth was the center of the solar system and that the sun revolved around the earth. l Early scientists said that the only elements were Earth, water, fire, and air.
Science Continued... l Myth and superstition drove science for hundreds of years. l This occurred from lack of knowledge and understanding of the world.
*Myth and superstition were then replaced by... *Myth and superstition were then replaced by... Fact and Knowledge!!
What inferences do you draw from observing the following? l your classmate wears a UW sweatshirt l a damaged car parked at the curb l broken tree limb in a neighbor’s yard Inference: interpretation based on indirect evidence
Observation vs. Inference* l Observation = What you see, hear, feel, etc. (using your 5 senses!) > ex.) “The sky is cloudy” l Inference = Conclusions that you make based on your observations > ex.) “It’s going to rain today”
Hypotheses l Science proceeds by testing hypotheses. l Hypotheses are tentative explanations of observed phenomena l Purpose of scientific experimentation is to test hypotheses.
Compare a hypothesis with a theory* l hypothesis: tentative explanation of observed phenomenon l theory: explanation which is supported by many experimental events and evidence
How does science influence you everyday? l cars l televisions l food/water l your home l electricity/computers l clothes l hygiene/health l ecosystems/the environment l etc.
Concerns in Science l Just because we can, does it mean we should? l Science is full of ethics, and we must remember our responsibility to our world.
Science is Changing Constantly l Technology has allowed science to grow rapidly and provide us with products to live our lives. l This has caused other problems around the world (pollution, etc.). l What will the future bring?
Science as we know it today * l Driven by fact and knowledge. l Still lots of trial and error. l Follows the “scientific method” and scientific inquiry. l Many good and bad outcomes have come from science.
Bad Outcomes of Science l Weapons of mass destruction l Biological warfare/epidemics l pollution, greenhouse effect, ozone hole, habitat destruction, extinction of species, loss of biodiversity, etc.
Good Outcomes of Science l Foundation of understanding for our world/knowledge l Cures for deadly diseases/health l food preservation l housing/amenities l entertainment l technology!
Science Branches l physical science: the study of matter and energy through physics and chemistry l earth science: geology, astronomy, meteorology, oceanography l biology/life sciences: studies living things, both animals and plants, etc. (botany, zoology, microbiology, etc.)
Scientific Method* l State the problem l Gather information on the problem l Form a hypothesis l Perform experiments to test the hypothesis l Record and analyze data l State a conclusion (a statement based on the results of the experiment) l Repeat the work
Vocabulary Review * l hypothesis-proposed solution to a scientific problem l variable-factor being tested in an experiment l control-standard with which to compare results l data-recorded observations and measurements
Science in the Future l It is now up to us to make educated choices and decisions in favor of the environment and our planet. l 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 l 1. In the center of your page, write l “What is Science?” l 2. Answer this question from your perspective. What does it mean to you? (2-3 sentences) l 3. Cut and paste 8 “Science” pictures from magazines around the page in a collage format. l 4. Write down 8 science words around the page (collage format). l 5. At the bottom of the page, explain your project in a couple complete sentences!
Homework l Finish your Science Collage assignment, due tomorrow! l Signed Policy Sheets due tomorrow!
