|
What is data?
|
It is INFORMATION gathered during an experiment

What does choose a problem (step 1) mean?
|
What do you want to know or explain? Use observations you have made to write a question that addressses the problem/topic you want to investigate. Choose something that you don't know the answer to.

|
What is step 3 of the S.M.?
|
Develop a hypothesis
|
|
|

|
It means...what do you THINK will happen? Predict the answer to your question or the outcome of the experiment. It is a statement that tries to explain a relationship between variables. Use the words IF and THEN. Form your hypothesis from a simple question. Your hypothesis must be VERY CLEAR so you can test it.
|
|
|
What is step 4 of the S.M?

|
|
What does write your procedures mean (step 4)
|
Tell what you will do to test YOUR hypothesis. List the materials you need. List each thing you do and number the steps. Write down everything you do so others can repeat your experiment by reading your procedures. Control your variables. Basically, develop a procedure for a reliable experiement and address safety rules.

|
|

|
|
|

|
|
|
What does organize your data mean (step 6)

What does state your conclusion mean (step 7)
|
Write a conclusion that summarizes the important parts of your experiment and the results. Was it what you expected? Did you find out what you wanted to know?
|
|
|
Once you organize your data (step 6) and you realize your data is inaccurate or the experiment flawed what do you do?
|
You research your problem. Rewrite your procedure to address the flaws in the original experiement.
