What does S.T.E.M. stand for?

Science -

Method of finding out about the natural world through observations and experiments.

Science can be a noun and a verb.

Technology -

The knowledge and skills available to a society.

Technology has been around much longer than science.

Engineering -

Application of knowledge to design and or build something useful

Engineers want to make things better.

Mathematics -

The study of numbers, shapes and patterns.

Math is the language of science.

Assignment:

Read and annotate Lesson 1

Chapter 1Lesson 1

Observing -

Using senses to gather information.

Types of Observations

Describing without numbers.

Qualitative Observation

Describing with numbers.

Quantitative Observation

Activity 1 – Making Observations

Explain or interpret things you observe.

Inferring (making an inference) -

Making a statement about the future based on prior observations.

Predicting -

Grouping items together that are alike.

Activity 2 – Using Science to Find Out

Lesson 2 – Thinking Like a Scientist

What qualities do scientists possess?

Scientists possess these qualitites

Curiosity, Honesty,Creativity,Open-mindedness,Skepticism,Good ethics,Bias awareness

Skepticism -

Having an attitude of doubt.

Ethics -

Rules of right and wrong

Bias - Influence the outcome one way

or another; unfair.

A biased experiment is not good. Why?

Scientific Reasoning - Logical way of thinking based on

gathering and evaluating evidence.

Scientific reasoning must be objective not subjective.

Objective -

Subjective -

Not based on opinion

Based on opinion or personal feelings

Deductive Reasoning - Applying a general idea to a

specific observation.

general to specific

Inductive Reasoning -

Using a specific observation to form a general conclusion.

specific to general

Faulty reasoning will form a wrong conclusion.

Lesson 3 – Scientific Inquiry

“heavier objects fall faster than lighter ones.”Deductive or Inductive Reasoning?

Demo – free-fall tube with vacuum

Specific to general conclusion.

Demo – drop paper with baseball

Lesson 3 – Scientific Inquiry

Scientific Inquiry -

trying to find an answer to a question

Read Page 18

What does inquire mean?

1. Pose a Question

2. Develop a Hypothesis

3. Conduct an Experiment

4. Form a Conclusion

Possible Steps in Scientific Inquiry

Hypothesis -

A possible answer to a question.Must be testable!

Experiment -

The test of a hypothesis.

Variables -

Purposely changed by the experimenter; independent variable

Manipulated Variable -

Factors that can change in an experiment.

Responding Variable - Variable the may be observed to

change in the experiment; dependent variable

Controlled Experiment -

Facts, figures, evidence gathered from the experiment.

Data -

Only one variable is changed at a time.

Graphs can help reveal patterns in data.

Conclusion -Results of what was discovered in

the experiment.
