  1. S.T.E.M. What does S.T.E.M. stand for? Science Technology Engineering Mathematics

  2. Science - Method of finding out about the natural world through observations and experiments. Science can be a noun and a verb.

  3. Technology - The knowledge and skills available to a society. Technology has been around much longer than science.

  4. Engineering - Application of knowledge to design and or build something useful Engineers want to make things better.

  5. Mathematics - The study of numbers, shapes and patterns. Math is the language of science.

  6. Assignment: Read and annotate Lesson 1

  7. Chapter 1 Lesson 1 Observing - Using senses to gather information.

  8. Types of Observations Qualitative Observation Describing without numbers. Quantitative Observation Describing with numbers.

  9. Activity 1 – Making Observations

  10. Inferring (making an inference) - Explain or interpret things you observe. Predicting - Making a statement about the future based on prior observations.

  11. Classifying - Grouping items together that are alike. Evaluating - Forming a conclusion based on observations and data.

  12. Making Models - Creating a representation of an object or process.

  13. Quiz! 1. What does S.T.E.M. stand for? 2. What word MUST be in any good definition of science? 3. What do all scientists do? 4. What do all engineers do? 5. Do you think that you would make a good engineer? Explain why or why not.

  14. Activity 2 – Using Science to Find Out

  15. Lesson 2 – Thinking Like a Scientist What qualities do scientists possess?

  16. Scientists possess these qualitites Curiosity, Honesty, Creativity, Open-mindedness, Skepticism, Good ethics, Bias awareness

  17. Skepticism - Having an attitude of doubt. Ethics - Rules of right and wrong

  18. Bias - Influence the outcome one way or another; unfair. A biased experiment is not good. Why?

  19. Scientific Reasoning - Logical way of thinking based on gathering and evaluating evidence. Scientific reasoning must be objective not subjective.

  20. Objective - Not based on opinion Subjective - Based on opinion or personal feelings

  21. Deductive Reasoning - Applying a general idea to a specific observation. general to specific

  22. Inductive Reasoning - Using a specific observation to form a general conclusion. specific to general

  23. Faulty reasoning will form a wrong conclusion.

  24. Lesson 3 – Scientific Inquiry Read Page 18 “heavier objects fall faster than lighter ones.” Deductive or Inductive Reasoning? Specific to general conclusion. Demo – drop paper with baseball Demo – free-fall tube with vacuum

  25. Lesson 3 – Scientific Inquiry Read Page 18 What does inquire mean? Scientific Inquiry - trying to find an answer to a question

  26. Possible Steps in Scientific Inquiry 1. Pose a Question 2. Develop a Hypothesis 3. Conduct an Experiment 4. Form a Conclusion

  27. Hypothesis - A possible answer to a question. Must be testable!

  28. Experiment - The test of a hypothesis.

  29. Variables - Factors that can change in an experiment. Manipulated Variable - Purposely changed by the experimenter; independent variable Responding Variable - Variable the may be observed to change in the experiment; dependent variable

  30. Controlled Experiment - Only one variable is changed at a time. Data - Facts, figures, evidence gathered from the experiment. Graphs can help reveal patterns in data.

  31. Conclusion - Results of what was discovered in the experiment. ASSIGN: Read and Annotate Pages 18- 26

  32. Evidence -
