  1. Fourth Grade Science Fair

  2. Decisions, decisions…. Experimental or Non-experimental ?????

  3. Help your child decide which type of project he or she would like to do Experimental – completing an experiment Non-experimental – researching a topic Decide if your child is going to work independently or with a group of no more than 4 students Decide on the project idea and get this approved by your child’s teacher First Tasks

  4. Requirements • Height- 48”X48” • What’s not allowed… • No access to water or electric • No live animals, if animal is harmed • No mold and bacteria

  5. Experimental Projects

  6. Background Information: • Include information that adds to the understanding of the project • Research from books, articles, or the web • Definitions in a glossary you create • Interview of an authority in your topic • Summary/ analysis of background information should be evident • If you attach web pages, please summarize them in your own words and explain how the information relates to your project. • Do not place on the back of the board.

  7. Sources You must include at least 3! Examples: 1. Title of book, Author, Date Published, Pages used • Web address, date accessed • Name of Encyclopedia, Name of Entry used, Date Published, Pages used • Name of Magazine, Name of article, Author, Date Published, Pages of article

  8. Problem: • What is the one question you want answered? • State it separately from the title. Indicate the effect of the manipulated / independent variable on the responding / dependent variable. • Ex. How does amount of fertilizer affect grass height?)

  9. Hypothesis: • What is your educated guess? Make your prediction clear. Word your hypothesis in a logical “If…, then…” declarative statement. Give reasons to support your prediction • EX. • If you double the amount of fertilizer (independent variable), then the grass will grow taller (dependent variable). In my research, I learned that fertilizer has plant nutrients. I need nutrients to grow taller, so I predict that plants will need lots of nutrients to grow taller.

  10. Materials: • List the things you will use to complete your experiment. Be specific. Give exact measurements and units. • EX: 30 Tablespoons of Miracle Grow

  11. Procedure: • What are the steps you will follow? • Number your steps. • Make your steps picture perfect, so someone could repeat your experiment. Include precise measurements. You may include diagrams along with the steps.

  12. Variables: • The independent variable is the one variable you change or manipulate(EX Amount of fertilizer is changed.) • The dependent variable is the variable that changes or what you are measuring- growth, speed, distance, etc.(EX The height of the grass was measure in mm) • The constant or control variables are all the things that stayed the same in the experiment.(EX Each cup had the same amount of soil, grass seeds, water, sunlight, temperature…) )

  13. Refer to the workbook for wording of variables…. • Independent Variable: The one variable I changed was ______________ • Dependent Variable: ________________was measured using _(unit) • Constant or Control Variable: The variables that stayed the same for all trials were: ______________________________________

  14. Data: • What actually happened? • What did you observe? • Write the independent and dependent variable on your data chart/table. Write clearly and neatly in charts or tables. • A sufficient amount of data should be collected through a sufficient number of trials (minimum of 3 trials- repeat 3 times). • Calculate averages of trials. Be sure to include a title and labels/units.

  15. Data Chart Sample Independent Variable/ One thing you changed: Amount to Fertilizer Added to Plant Dependent Variable/ The thing you are measuring: Height of plant each day

  16. Results: • Use graphs. Use TAILS! Graph correctly. The dependent variable (what you measured) goes on the Y axis. The independent variable (what you changed) goes on the X axis. Photos and/or drawings may be appropriate to supplement. Write a paragraph to summarize and explain your observations and data. This is technical writing, so refer back to your findings as you put your data numbers into sentences.)

  17. Great site for making graphs: http://nces.ed.gov/nceskids/createAgraph/

  18. Sample Graph- TAILS- Title Axis Intervals Labels Spacing Dependent Variable Independent Variable

  19. Conclusion: • Restate your hypothesis and clearly explain if your hypothesis was rejected or accepted -use these terms!. • Support your answer using numbers from your data!

  20. Discussion: • Clearly write in paragraph form. Include flaws/ errors which could have affected results. • You may also include ideas for further research on the topic. • Discuss how you could apply your results to real life situations. • Explain what you learned by completing this project.

  21. Sample Science Fair Board Layout:

  22. Non-Experimental Project

  23. Purpose • What was the reason for doing this investigation?

  24. Scientific Process Skills • Observation • Comparison • Classification • Organization • Measurement • LABEL EACH ON PROJECT

  25. Graphs, Charts, and/or Pictures • In addition to actual graphs, charts, and/or pictures you must tell exactly what each represents or demonstrates. This explanation should be in paragraph form. All graphs must have appropriate labels.

  26. Scientific Information • This is a student created report with facts, descriptions, and information about this project. This must be grade and age appropriate.

  27. Sources of Information/Materials You must have at least 3 sources! Examples: • Title of book, Author, Date Published, Pages used • Web address, date accessed • Name of Encyclopedia, Name of Entry used, Date Published, Pages used 4. Name of Magazine, Name of article, Author, Date Published, Pages used)

  28. Child Made Model Include a paragraph and/or labels! Connect it to your project.

  29. Discovery • What did you learn from doing this project? • Write it in paragraph form!
