Goals of Science Investigate and understand nature Explain events in nature Make useful predictions Never stop questioning

Definition of Science An organized way of using evidence to learn about the natural world. The body of knowledge that scientists have built up after years of testing proposed explanations.

Observations The first step to “doing” science Involves using one or more of the senses Sight Hearing Touch Smell Taste

Observations Will raise a question.

Observations To gather… Information Evidence Data

Inference Follows an observation A logical interpretation based on prior knowledge and experience Uses what you know to figure something out

Inference Observation or Inference? There are two dogs.The little dog stole the big dog’s bed.The big dog is in the little bed.The little dog is mad.The big dog is sleeping.The little dog is in a big bed.There are two dog beds.There is a chair by the dog beds.The dogs are not allowed in the chair.The dogs are friends.The big dog is happy.The little dog is gray.The little dog is old.

Observation or Inference? Can we make the same assumptions (Inferences based on observations) about this picture as we did the last one?

Observations and Inferences Observation: ___________________ Inference: Owls live in trees Observation: The owl has wings, Inference: ___________________ Owl perched in tree Owls can fly

Hypothesis A tentative statement that proposes a possible explanation to some phenomenon or event A tentative statement that proposes a possible explanation to some phenomenon or event Attempts to explain a set of observations Attempts to explain a set of observations May arise from logical inferences May arise from logical inferences

Hypothesis Uses prior knowledge Is an educated guess or a trial answer Is a testable statement which may include a prediction

Importance of Science Importance of Science Science helps us to understand the world around us and to appreciate it's complexities It underlies our health, our work, our communications, our entertainment and our transport It permeates our lives and informs our actions Science is a way of thinking, fun, dynamic, constantly changing

Importance of Science Importance of Science Science contributes to our understanding of health and disease and enables medical progress It shows us our impact on the environment and our world It empowers us to make technological advancements As scientific knowledge grows, so does our understanding of the universe

What Science Isn’t Scientific knowledge is not the absolute truth It is based only on available evidence It is subject to modification in light of new evidence and new ways of thinking Science is limited to the study of the natural world and cannot study or explain supernatural events

A Unique Endeavor What three things make science different from other human endeavors? What three things make science different from other human endeavors? It deals only with the natural world It deals only with the natural world Scientists collect and organize information in a careful, orderly way, looking for patterns and connections between events Scientists collect and organize information in a careful, orderly way, looking for patterns and connections between events Scientists propose explanations that can be tested by examining evidence Scientists propose explanations that can be tested by examining evidence

A Good Scientist: What qualities make for a good scientist? Curious Honest Open minded Persistent Skeptical Patient and careful Recognize limitations of science Believe in cause and effect Concern for mankind
