  1. TitleYou can use your question as your title.But an even better title is one that catches attention – a clever phrase or an alliteration.

  2. Question • The best topic will be about something that you enjoy. Think about things that you are interested in and make a list of what you know and what you want to know about the topic. • Another way to come up with a topic is to think of something you have seen (like a paper airplane flying across a room) and ask yourself a “I wonder what would happen if…” question (I wonder what would happen if I made the airplane out of cardboard, would it fly farther?). • Once you have an idea about what you want your experiment to be, then you need to phrase it as a question – a question that you need to do an experiment to answer.

  3. Background Information • Write down what you know about your topic and any questions you may have. • Go to the library, internet, etc., and research your topic. • This will be different for each topic.

  4. Hypothesis • A hypothesis is a prediction or educated guess about what will happen in your experiment. Use your past experiences and what you already know about your topic to help you make a hypothesis. • A hypothesis can be stated as an “if - then” statement. “If I do this, then I think this will happen.” • Example: If I make a paper airplane from construction paper, then I think it will fly farther than an airplane made from regular computer paper. • Before you write your hypothesis, you need to decide what you are going to change and what you are going to measure in your experiment. • IF YOUR DATA DISPROVES YOUR HYPOTHESIS DO NOT CHANGE YOUR HYPOTHESIS! Disproving your hypothesis can lead to amazing new discoveries and can make your project even more exciting.

  5. Variables • Independent Variable (manipulated variable) _____________________________ • Dependent Variable (responding variable) _____________________________ • Controlled Variables ____________________________________________________________________

  6. Materials • Make a detailed list of what you need to do your experiment. • Remember measuring tools and safety equipment. • Try to list out exact measurements of materials if you know them (use metric measurements). • If you are using a specific brand name – name it. • Make sure you have enough material to do at least 3 repetitions. • If you think of something you will need as you are doing your experiment, make sure you add it to your materials list.

  7. Experimental Procedure • Write a step by step procedure, list out exactly what you are going to do. • You want your procedure to be so detailed that another student could follow your procedure and do the experiment exactly the same way you did. • If you think of details as you are doing your experiment or make changes in your procedure, be sure to write those changes down in your procedure as well. • Make sure you are repeating your experiment at least 3 times.

  8. Data Collection • All experiments require data. • During your experiment keep a log of the data you collect and any observations you make. • Before you start your experiment, make a data table where you can collect your data. • If something unexpected happens as you are collecting your data – write it down! • Take photographs as you are doing your experiment.

  9. Results • You have collected your data –now what do you do? • Average your data. • Use a graph to help explain your data. • Choose a type of graph that will best show any patterns, changes (or lack of changes) in your data • Circle Graph (pie chart) • Bar Graph • Line Graph • Use photographs to illustrate changes.

  10. Conclusions • What did you find out from your experiment? • Was your hypothesis correct? If not how was it different? • Were your results the same for each repetition? • What problems did you have? How could you correct them in the future? • What would you do differently if you did this experiment again?

  11. References • List any resources you used – try to use at least 3 and try to use more than one type of reference, i.e., books, magazines, internet, interviews of experts, etc…

  12. Acknowledgements • Thank any person who helped you with your project.
