There are several correct answers to this question; list as many as you can.

3. What is SCIENCE? 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

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

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

6. Describe DESCRIPTIVE RESEARCH

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

8. Describe EXPERIMENTAL RESEARCH

9. Describe EXPERIMENTAL RESEARCH
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

10. Describe VARIABLE

11. A part of an investigation that can be CHANGED
Describe VARIABLE
A part of an investigation that can be CHANGED

12. List the 3 TYPES OF VARIABLES

13. List the 3 TYPES OF VARIABLES
Independent Variable
Dependent Variable
Controlled Variable

14. Explain INDEPENDENT VARIABLE

15. Explain INDEPENDENT VARIABLE
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

16. Explain DEPENDENT VARIABLE

17. Explain DEPENDENT VARIABLE
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

18. Explain CONTROLLED VARIABLE (CONSTANT)

19. Explain CONTROLLED VARIABLE (CONSTANT)
Variable that stays the same during an experiment
Variable that is controlled by the scientist
Variable that is not allowed to change

20. What is the difference between Science and Technology?

21. What is the difference between Science and Technology?
Technology is the application of science;
Science  gaining knowledge
Technology  using knowledge

22. How do scientists OBSERVE?

23. How do scientists OBSERVE?
Using the 5 senses:
Hearing
Touch
Smell
Sight
Taste

24. Explain how to RECORD DATA

25. Explain how to RECORD DATA
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

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

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

28. Describe how to ANALYZE DATA

29. Describe how to ANALYZE DATA
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

30. What do scientists do when they DRAW CONCLUSIONS?

31. What do scientists do when they DRAW CONCLUSIONS?
Answer the original question
State whether or not the hypothesis was supported (it is never “right” or “wrong”)
Pose questions for further research

32. Define HYPOTHESIS

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

34. Why are REPEATED TRIALS necessary in an experiment?

35. Why are REPEATED TRIALS necessary in an experiment?
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

36. Why do scientists use MODELS?

37. Why do scientists use MODELS?
To save time and money when testing ideas that are
Very large
Very small
Dangerous
Time-consuming

38. When are GOGGLES required?

39. When are GOGGLES required?
When using
Chemicals
Heat
Sharp objects

41. Explain the Science Department Late Work Policy
No late work is accepted.
