The Scientific
Method involves a
series of steps that
are used to find an
answer to a
problem.
The steps of the scientific
method.
1)Observation
AH—Look at this!

Observe a problem or
anything around you
Example:
Observe the skittles in front of
you.

Record your observation.

2) Question
Develop a question or
problem that can be
solved through an
experiment.

Q) Will?
3) Research
After you search the internet
and the books for information
you find out that:
Lemon, vinegar and tomato sauce
can be use ...
After you made your
research,
Can you guess an answer to
your question?
3) Hypothesis
An educated guess.

Lemon juice can be
used to clean the dull coin.
NOW, lets test
whether our
hypothesis is right
or wrong.
4) Experiment
Make a test to test
whether the hypothesis
is correct.

1)Put the coin in the
lemon juice.
2) Wait for 5 min...
5) Record results
In tables, graphs.

6) Conclusion

question (you state
whether your hypothesis
was right or wrong)..

Transcript of "Scientific method(br.)"

  1. 1. The Scientific Method involves a series of steps that are used to find an answer to a problem.
  2. 2. The steps of the scientific method.
  3. 3. 1)Observation AH—Look at this! Observe a problem or anything around you
  4. 4. Example:
  5. 5. Observe the skittles in front of you. Record your observation. Observation Color skittles 1 skittles 2 Dull Shiny
  6. 6. 2) Question Develop a question or problem that can be solved through an experiment. Q) Will?
  7. 7. 3) Research
  8. 8. After you search the internet and the books for information you find out that: Lemon, vinegar and tomato sauce can be use to clean silver and metal objects
  9. 9. After you made your research, Can you guess an answer to your question?
  10. 10. 3) Hypothesis An educated guess. Lemon juice can be used to clean the dull coin.
  11. 11. NOW, lets test whether our hypothesis is right or wrong.
  12. 12. 4) Experiment Make a test to test whether the hypothesis is correct. 1)Put the coin in the lemon juice. 2) Wait for 5 min. and record the results.
  13. 13. 5) Record results In tables, graphs. Dull coin After 5 min. in the lemon juice Shiny
  14. 14. 6) Conclusion The answer to the question (you state whether your hypothesis was right or wrong).. The lemon juice cleans the dull coin.
  15. 15. Any experiment has Variables
  16. 16. WHAT ARE Variables?
  17. 17. Variables Variables are things that vary and change
  18. 18. In any experiment there are 3 variables: Things you change Things you measure Things you keep the same to have a fair test Let’s look at each type….
  19. 19. Example 1: Investigating how a weight affects the length of an elastic band. You decide the weight to put. You measure the length of the elastic band. You use the same elastic band to have a fair test.
  20. 20. Example 2: Investigating how the rate of cooling of a beaker depends on the initial temperature. You decide the initial temperature. You measure the rate of cooling. You use the same thermometer, same amount of liquid to have a fair test.
  21. 21. Example 3: Students of different ages were given the same jigsaw puzzle to put together. They were timed to see how long it took to finish the puzzle. You decide the ages of students. You measure the time they to finish the puzzle. You use the same jigsaw puzzle to have a fair test.
  22. 22. Example 4: The higher the temperature of water, the faster an egg will boil. You decide the temperature of the water. You measure the time it took the egg to boil. You use the same type of egg to have a fair test.
  23. 23. Example 5: The temperature of water was measured at different depths of a pond. You decide the depth of the pond. You measure the temperature of the water. You use the same thermometer to have a fair test.
