STEP 1 - Ask a Question: Asking a question is important because, if you don't ask a question, you won't have anything to test.
STEP 2 - Make a Hypothesis: A hypothesis is an educated guess. The hypothesis is important because it usually has an "if then" statement, which gives you the steps you will need to follow in the experiment.
STEP 3 - Experiment: The experiment is EXTREMELY important because, if you don't test anything, you will never know for sure what will happen. Also you will never know the right way to do it or what works best.
STEP 4 - Collect Data: You collect data because it shows the results of the experiment. If you don't collect data, you are going to have a lot to remember and it would be a lot easier to just put your findings on some type of data collector. If you know what I mean.
STEP 5 - Form a Conclusion: A conclusion is awesome because it brings all of the other 4 steps and any loose ends together, which forms a conclusion. Then you can share all of your work and help others.
The dependent variable is a result of the independent variable. The independent variable is the variable that the scientist changes on purpose. EX: The amount of toppings on a pizza (the I.V.) affects the cost of the pizza (the D.V.).
