Choose a Topic Pick a topic that will be interesting and will be able to be completed on time.
Title • Choose a title that reflects your topic and is in the form a question. Example: How does vinegar affect a penny?
Purpose • Write 1 to 3 sentences describing what you want to find out in this project. Example: The purpose of this project is to find out what will happen when vinegar is placed along side a penny.
Research • Research should be completed to learn background information about your topic. This will help you complete the experiment accurately. • Develop 3 questions that you want to answer about your topic. • Use a variety of sources for your research. • Use books and the internet. Save the URL into a word document so you have the website’s address.
Does the penny get cleaner? • Does the penny rust? • Is there a chemical or physical reaction with the penny and the vinegar?
Hypothesis Make your guess • Use your research to make an educated guess about how you think your experiment will turn out. • The If… then format must be used. “ If I __________ then _____”format Example: If a penny is placed on a paper towel that contains 20 drops of vinegar, then the penny will increase in luster.
Procedure • Design your experiment • Design your experiment so that it only tests for one variable. • Make sure all other variables are controlled. • Make sure to keep a control group. • Keep in mind sample size. • The more objects in your sample the more valid your experiment. • Use multiple trials. (At least three.)
Procedure • Example: If you are testing pennies and vinegar: • Use the same luster of penny. • Use the same brand and type of vinegar. • Use the same amount of vinegar.
Procedure • Write down step-by-step directions on how to do your experiment. • Do not leave anything out! • Write everything down so that another scientist can replicate your experiment exactly as you have completed the experiment.
Materials Pennies Vinegar Paper towel Petri dishes
Procedure • Get 1 pennies of similar luster. • Place paper towel into petri dish • Drop 20 drops of vinegar onto the paper towel • Place 1 of the pennies in a petri dish on a paper towel • Place petri dishes is a safe place for 24 hours. • Compare the 1 pennies from the petri dish to the pennies that were not placed in the petri dish. • Record data
Do your experiment. The experiment may need to be completed multiple times to be sure correct results are made.
Make Charts and Graphs • Display data using charts, tables, and graphs. • Use the Graph Club or Inspiration program. • Choose the correct graphs for your data. • Bar-comparison • Pie-percentage • Line-change/time
Results • Using your data write a few sentences how your experiment turned out.
Conclusion • Write down why you think your experiment turned out the way it did, include if your hypothesis was supported or not. • Be sure to use the term “ My hypothesis was/was not supported. • Do not say I was right/wrong. • Even when your hypothesis was not supported you gain information about your topic. • Use scientific reasoning for conclusion.
Conclusion • Example: My hypothesis was supported. The plants that were watered with coffee ( caffeine ) grew taller than those that were given water. Therefore, caffeine has a positive effect on the growth of pea plants. This may be due the fact that caffeine is a stimulant. The caffeine could have stimulated the plant to grow.
Future Considerations • Tell what variable you would change if you could do the experiment again. • Tell how you might take your experiment to the next step.
Future Considerations • Example • If I could do this experiment again , the variable I would change would be the amount of caffeine I would place in each plant group. I would use 50ml for plant group #1, 100ml for plant group #2, and 150ml for plant group #3. I would also have three “control groups” of plants. One would get 50ml of water. One would get 100ml of water. And one would get 150ml of water. I want to see which amount of caffeine helps plants grow the tallest.
Make Your Board • Start your information on the top left panel of the board, move down the left panel, across the middle panel, and from the top down on the right panel. • Place pictures of your experiment on your board.
Bringing It Together Keys for success: • Make a time-line and stick to it. • Parental support • Organization
