1 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 Life science Physical science Physical science Earth science Earth science Space 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 EXPERIMENTAL DESIGN Organized method used to solve problems and answer questions

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

7 GATHER INFORMATION Think about your own experiences with this topic Think about your own experiences with this topic Do research Do research Who else studied this and what did they find out 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. Pose a testable explanation. What do you think is going to happen? What do you think is going to happen? Make an educated guess 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 A set of steps to follow to test the hypothesis Observe and record all information Observe and record all information Be sure to identify the controls, constants, and variables 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 CONTROLS CONTROLS The standard to which the outcome of a test is compared The standard to which the outcome of a test is compared What you measure against What you measure against CONSTANTS The things that remain the same

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

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

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

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

15 DRAW A CONCLUSION A logical answer to a question based on data and observations 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 experiment needs to be repeated several more times The results need to be shared with the scientific community 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 results need to be shared with the scientific community The hypothesis needs to be revised and tested again The hypothesis needs to be revised and tested again

18 REVIEW TIME REVIEW TIME

19 What is Science? An organized way of studying things and finding answers to questions An organized way of studying things and finding answers to questions

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

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

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

23 What is a control? What you compare against What you compare against

24 What are constants? Things that stay the same 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 What is changed or tested

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

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

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

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