1. CHAPTER 1 MS. PAREKH

2. WHAT IS SCIENCE? SCIENCE IS THE INVESTIGATION AND EXPLORATION OF NATURAL EVENTS AND THE NEW INFORMATION THAT RESULTS FROM THOSE INVESTIGATIONS

3. WHAT ARE THE THREE BRANCHES OF SCIENCE? EARTH, LIFE, AND PHYSICAL

4. WHAT IS PHYSICAL SCIENCE? THE STUDY OF ENERGY AND MATTER

5. WHAT IS LIFE SCIENCE? THE STUDY OF ALL LIVING THINGS

6. WHAT IS EARTH SCIENCE? THE STUDY OF ROCKS, SOILS, OCEANS, AND THE ATMOSPHERE

7. WHAT IS ANOTHER NAME FOR THE SCIENTIFIC METHOD? SCIENTIFIC INQUIRY

8. WHAT ARE THE STEPS OF THE SCIENTIFIC METHOD? OBSERVATION, QUESTION, INFERENCE, HYPOTHESIS, PREDICTION, TEST HYPOTHESIS, ANALYZE RESULTS, DRAW CONCLUSIONS, COMMUNICATE RESULTS, AND FURTHER SCIENTIFIC INQUIRY

9. WHAT IS AN OBSERVATION? USING ONE OR MORE OF YOUR SENSES TO GATHER INFORMATION

10. WHAT IS THE DIFFERENCE BETWEEN AN INFERENCE AND A HYPOTHESIS? AN INFERENCE IS AN EXPLANATION BASED ON PRIOR KNOWLEDGE OR EXPERIENCE WHILE A HYPOTHESIS IS AN EXPLANATION THAT CAN BE TESTED BY SCIENTIFIC INVESTIGATION.

11. WHAT IS A PREDICTION? A STATEMENT OF WHAT WILL HAPPEN NEXT IN THE SEQUENCE OF EVENTS.

12. WHAT IS THE DIFFERENCE BETWEEN A SCIENTIFIC THEORY AND A SCIENTIFIC LAW? A SCIENTIFIC THEORY IS AN EXPLANATION OF OBSERVATIONS BASED ON KNOWLEDGE GAINED FROM MANY OBSERVATIONS AND INVESTIGATIONS WHILE A SCIENTIFIC LAW IS A STATEMENT THAT SOMETHING WILL HAPPEN UNDER CERTAIN CONDITIONS.

13. WHAT IS TECHNOLOGY? TECHNOLOGY IS THE PRACTICAL USE OF SCIENTIFIC KNOWLEDGE, ESPECIALLY FOR INDUSTRIAL OR COMMERCIAL USE.

14. WHAT ARE THE THREE RESULTS OF SCIENCE? TECHNOLOGY, NEW MATERIALS, AND POSSIBLE EXPLANATIONS

15. WHAT IS CRITICAL THINKING? CRITICAL THINKING COMPARES WHAT YOU ALREADY KNOW WITH THE INFORMATION YOU ARE GIVEN IN ORDER TO DECIDE WHETHER YOU AGREE WITH IT.

16. WHAT IS THE DIFFERENCE BETWEEN A FACT AND AN OPINION? A FACT IS A STATEMENT THAT CAN BE STRICTLY DEFINED WHILE AN OPINION IS A PERSONAL VIEW ABOUT A TOPIC.

17. WHAT IS A DESCRIPTION? A DESCRIPTION IS A SPOKEN OR WRITTEN SUMMARY OF OBSERVATIONS

18. WHAT ARE THE TWO TYPES OF DESCRIPTIONS? QUALITATIVE AND QUANTITATIVE

19. WHAT IS A QUALITATIVE DESCRIPTION? WHEN YOU USE YOUR SENSES TO DESCRIBE AN OBSERVATION EXAMPLE: THE MILK SMELLS SOUR

20. WHAT IS A QUANTITATIVE DESCRIPTION? WHEN YOU USE NUMBERS AND MEASUREMENTS TO DESCRIBE AN OBSERVATION EXAMPLE: THE GIRL IS SEVEN YEARS OLD

21. WHAT IS AN EXPLANATION? AN INTERPRETATION OF OBSERVATIONS

22. WHAT IS THE INTERNATIONAL SYSTEM OF UNITS? THE INTERNATIONALLY ACCEPTED SYSTEM FOR MEASUREMENT WITH STANDARDS OF MEASUREMENT CALLED BASE UNITS

23. WHAT INDICATES THE SIZE OF THE BASE UNIT? PREFIX

24. WHAT ARE SIGNIFICANT DIGITS? THE NUMBER OF DIGITS AND A MEASUREMENT THAT YOU KNOW WITH A CERTAIN DEGREE OF RELIABILITY

25. WHAT ARE MEAN, MEDIAN, MODE, AND RANGE? MEAN IS THE AVERAGE – ADD UP ALL THE NUMBERS AND DIVIDE BY THE NUMBER OF NUMBERS MEDIAN IS THE MIDDLE NUMBER – WHEN THE NUMBERS ARE IN NUMERICAL ORDER FROM LEAST TO THE GREATEST MODE –IS THE NUMBER THAT OCCURS MOST FREQUENTLY RANGE – IS THE DIFFERENCE BETWEEN THE GREATEST NUMBER AND THE LEAST NUMBER

26. SIGNIFICANT DIGITS, MEAN, MEDIAN, MODE, AND RANGE KNOW HOW TO FIND A NUMBER OF SIGNIFICANT DIGITS AND HOW TO FIND MEAN, MEDIAN, MODE, AND RANGE

27. WHAT IS A VARIABLE? ANY FACTOR THAT CAN HAVE MORE THAN ONE VALUE

28. WHAT IS AN INDEPENDENT VARIABLE? THE FACTOR THAT YOU WANT TO TEST. IT IS CHANGED BY THE INVESTIGATOR TO OBSERVE HOW IT AFFECTS A DEPENDENT VARIABLE.

29. WHAT IS A DEPENDENT VARIABLE? THE FACTOR YOU OBSERVE OR MEASURE DURING AN EXPERIMENT
