4Avenues 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 hypothesespredictingconducting experimentsinterpreting data (drawing conclusions)developing theoriesapplying knowledge to solve problems
6Science is a ProcessIt 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.
7Science 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!!
9What inferences do you draw from observing the following? your classmate wears a UW sweatshirta damaged car parked at the curbbroken tree limb in a neighbor’s yardInference: interpretation based onindirect evidence
10Observation 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”
11Hypotheses Science proceeds by testing hypotheses. Hypotheses are tentative explanations of observed phenomenaPurpose of scientific experimentation is to test hypotheses.
12Compare a hypothesis with a theory* hypothesis: tentative explanation of observed phenomenontheory: explanation which is supported by many experimental events and evidence

14Concerns 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.
15Science 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?
16Science 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.
17Bad Outcomes of Science Weapons of mass destructionBiological warfare/epidemicspollution, greenhouse effect, ozone hole, habitat destruction, extinction of species, loss of biodiversity, etc.
18Good Outcomes of Science Foundation of understanding for our world/knowledgeCures for deadly diseases/healthfood preservationhousing/amenitiesentertainmenttechnology!
19Science Branchesphysical science: the study of matter and energy through physics and chemistryearth science: geology, astronomy, meteorology, oceanographybiology/life sciences: studies living things, both animals and plants, etc. (botany, zoology, microbiology, etc.)
20Scientific Method* State the problem Gather information on the problem Form a hypothesisPerform experiments to test the hypothesisRecord and analyze dataState a conclusion (a statement based on the results of the experiment)Repeat the work
21Vocabulary Review *hypothesis-proposed solution to a scientific problemvariable-factor being tested in an experimentcontrol-standard with which to compare resultsdata-recorded observations and measurements
22Science in the FutureIt 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.
