Learning TargetLearning Target

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

What is Science?What is Science?

Avenues of thinking and Avenues of thinking and knowingknowing

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!

WHAT IS SCIENCE?* 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 ProcessScience 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...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 *Myth and superstition were then replaced by...then replaced by...

Fact and Knowledge!!

What inferences do you What inferences do you draw from observing the draw from observing the

following?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 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”

HypothesesHypotheses

Science proceeds by testing hypotheses. Hypotheses are tentative explanations of

observed phenomena Purpose of scientific experimentation is

to test hypotheses.

Compare a hypothesis with Compare a hypothesis with a theory*a theory*

hypothesis: tentative explanation of observed phenomenon

theory: explanation which is supported by many experimental events and evidence

How does science influence How does science influence you everyday?you everyday?

cars televisions food/water your home electricity/computers clothes hygiene/health ecosystems/the environment etc.

Concerns in ScienceConcerns 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 Science is Changing ConstantlyConstantly

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 *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 ScienceBad 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 ScienceGood Outcomes of Science

Foundation of understanding for our world/knowledge

Cures for deadly diseases/health

food preservation housing/amenities entertainment technology!

Science BranchesScience 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*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 *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 FutureScience 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.
