SCIENCE
An organized way of studying things and finding answers to questions.

2. TYPES OF SCIENCE
Each type of science is given a name to describe what is being studied.

3. TYPES OF SCIENCE Life science Physical science Earth science
Space science
Studies plants, animals, and other living things
Studies energy, matter, and chemistry
Studies the processes that shape the Earth
The study of all things in the universe

4. TYPES OF SCIENCE

5. Organized method used to solve problems and answer questions
EXPERIMENTAL DESIGN
Organized method used to solve problems and answer questions

6. STATE THE PROBLEM Ask a question What are you trying to solve?
Which color Life Saver dissolves the fastest?

7. GATHER INFORMATION Think about your own experiences with this topic
Do research
Who else studied this and what did they find out
It has been my experience that I eat the green Life Savers faster than any other color

8. FORM A HYPOTHESIS Pose a testable explanation.
What do you think is going to happen?
Make an educated guess
I think the green Life Saver will dissolve faster than any other color.
I also think that purple will last the longest.

9. DESIGN AND PERFORM AN EXPERIMENT
A set of steps to follow to test the hypothesis
Observe and record all information
Be sure to identify the controls, constants, and variables
1. give each test subject a different color Life Saver
2. each test subject puts the Life Saver in their mouths at the same time
3. record the time it takes for the candy to dissolve

10. CONTROLS AND CONSTANTS
The standard to which the outcome of a test is compared
What you measure against
CONSTANTS
The things that remain the same

11. VARIABLES Something in an experiment that is changed or measured
The color of Life Savers was changed
The time to dissolve was measured

12. VARIABLES INDEPENDENT VARIABLE What is changed or different
What starts the experiment
Can only be 1
DEPENDENT VARIABLE
What is measured
The result

13. EXTRANEOUS VARIABLES Unexpected or unpredictable events
Improperly controlled experiment
EX: the Life Saver lab

14. ANALYZE THE DATA Determine what the data means
Make graphs and data tables

15. DRAW A CONCLUSION
A logical answer to a question based on data and observations
My data does not support my hypothesis, I said the green Life Saver would dissolve the fastest but the white one did.
The purple Life Saver did last the longest.

16. If the hypothesis is supported
The experiment needs to be repeated several more times
The results need to be shared with the scientific community

17. If the hypothesis is not supported
The results need to be shared with the scientific community
The hypothesis needs to be revised and tested again

18. REVIEW TIME

19. What is Science?

20. What are the 4 basic types of Science?
Life
Physical
Earth
Space

21. What is the first step in designing an experiment?
To state the problem or ask a question

22. What is a hypothesis?
A testable explanation
A prediction

23. What is a control?
What you compare against

24. What are constants?
Things that stay the same

25. How many variables can be tested at one time?1

26. What is an independent variable?
What is changed or tested

27. What is a dependent variable?
The result
What is measured

28. What is the easiest way to organize data?
Graphs and charts

29. If your hypothesis is supported what do you do next?
Repeat the experiment
Share the results

30. If your hypothesis is not supported what should you do?
Share your results
Revise and retest
