Statement of the Problem, Purpose, Hypothesis

Reminder: other than the recommendation section,
there are to be NO YOUs/ Mes/ we etc written!!

Statement of the Problem

This is a statement of what problem you hope to solve by what you have learned through your research and from your experiment. It is typically 2-3 paragraphs or 3/4 of a page.

example: Half the teenagers between the ages of 13 and 18 in our country use a skateboard on a daily basis. Over 25% of these teens suffer multiple injuries such as...


This is a statement of why you are doing this experiment. Why is your discovery important? This is usually a 1-3 paragraph section that answers these questions.

example: The purpose of this experiment is to see if there is a way to make teenage skateboard riders safer...


-remember that the hypothesis is always stated in the positive as an “If” and “then” statement
-it is an EDUCATED GUESS about the outcome (results) of your experiment. It is what you think might happen when you do your experimentation. What effects or results do YOU expect, based upon your BACKGROUND RESEARCH?
- The hypothesis usually is in the form of a brief statement. 1-2 paragraphs
- Hypothesis is to include a number or percentage. (It is QUANTIATIVE) which is supported by your research.

example: According to research on skateboard wheels, it is believe thay Brand X wheels will allow a skateboard to stop faster 75% of the experimental trials because they are fatter than Brands A, B, C, D, E...

- NOTE: A hypothesis does NOT have to be RIGHT to earn a top grade. Your goal is to collect experimental evidence to determine if your guess is correct. Report the results honestly!!! Sometimes the greatest knowledge COMES from an “incorrect” hypothesis!



Points to Remember:

1. Each section is to be on it's own page.
2. Same font and size as research paper
3. 1 1/2 point spacing
4. NO ME's, I's, or YOUs -
...... always written in a 3rd person

- Record these parts in your Science Project Log.
- You will also need a TYPED copy for your notebook
