3. What is SCIENCE? There are several correct answers to this question; list as many as you can.

4. A way to answer questions & solve problems How we understand the world around us A way or process used to investigate what is happening around you It provides possible answers What is SCIENCE?

5. We answer scientific questions & solve problems with 2 types of research. What are the two types?

6. We answer scientific questions and solve problems with 2 types of research. What are the two types? 1.Descriptive Research 2.Experimental Research

7. Describe DESCRIPTIVE RESEARCH

8. Based mainly on Observations Used when experiments are impossible to perform Involves the following: –Stating the research objective –Describing the research design –Eliminating bias Describe DESCRIPTIVE RESEARCH

9. Describe EXPERIMENTAL RESEARCH

10. Experimental research includes investigations that: Have variables Test hypotheses May have a control or control group Is a set of planned steps Tests one variable at a time

11. Describe VARIABLE

12. A part of an investigation that can be CHANGED

13. List the 3 TYPES OF VARIABLES

14. 1.Independent Variable 2.Dependent Variable 3.Controlled Variable

15. Explain INDEPENDENT VARIABLE

16. The variable that can be changed during an experiment The variable that the scientists chooses to change The variable that may cause a change in the dependent variable

17. Explain DEPENDENT VARIABLE

18. The factor that is being measured in an experiment The variable that is measured by scientists The variable that may change because of the independent variable

19. Explain CONTROLLED VARIABLE (CONSTANT)

20. Variable that stays the same during an experiment Variable that is controlled by the scientist Variable that is not allowed to change

21. What is the difference between Science and Technology?

22. Technology is the application of science; Science  gaining knowledge Technology  using knowledge

23. How do scientists OBSERVE?

24. Using the 5 senses: Hearing Touch Smell Sight Taste

25. Explain how to RECORD DATA

26. Data Tables A way to record results and observations accurately Have a descriptive title Divided into columns & rows Shows the independent variable Provides a place to record the dependent variable Explain how to RECORD DATA

27. How do scientists COMMUNICATE the results of their work?

28. Reported in scientific journals Science journals Presentations to other scientists How do scientists COMMUNICATE the results of their work?

29. Describe how to ANALYZE DATA

30. Reduce the data with the best measure of central tendency Graph the data Look for patterns and relations Look at the shape of the graph Describe how to ANALYZE DATA

31. What do scientists do when they DRAW CONCLUSIONS?

32. Answer the original question State whether or not the hypothesis was supported (it is never “right” or “wrong”) Pose questions for further research

33. Define HYPOTHESIS

34. A statement that can be tested by conducting an experiment Prior knowledge, new information, observations can be used to form a hypothesis

35. Why are REPEATED TRIALS necessary in an experiment?

36. To make sure results are valid The more trials conducted, the more likely the results are reliable To make sure a “fluke” is not considered the true result

37. Why do scientists use MODELS?

38. To save time and money when testing ideas that are Very large Very small Dangerous Time-consuming

39. When are GOGGLES required?

40. When using Chemicals Heat Sharp objects

41. Explain the Science Department Late Work Policy

42. 10 points will be taken off each day it is late!

43. What is the PROCEDURE for the Start of Class?

44. Come into the room and sit in your assigned seat. Read the AGENDA and copy assignments into your agenda. The agenda is located on the white board to the left of the door. Read the instructions of the overhead projector and follow the directions.
