  • Slide 1
  • Science Fair 2013-2014
  • Slide 2
  • Science Fair: Fact (green) or Myth (red) Parents are not supposed to help their child(ren). Logbooks can make or break a project. Science Fair projects take weeks if not months. Measurements should be in the metric system. Experiments should have only one variable changed. The best project ideas come from parents.
  • Slide 3
  • Logbook A logbook is a very detailed account of a project start to finish. It includes Actions Observations Research Drawings/Diagrams Thoughts Feelings Start your logbook today!
  • Slide 4
  • Project Ideas Ideas can come from anywhere! The best ideas come from questioning things around our everyday life, or creating a question from our own interests.
  • Slide 5
  • Project Categories Behavioral and Social Sciences (BSS) Biochemistry (BBC) Botany (BBO) Environmental Science (BEV) Medicine and Health (BMH) Microbiology (BMB) Zoology (BZO) Chemistry (PCH) Earth and Space (PES) Engineering (PEG) Mathematics (PMC) Computer Science (PCS) Physics (PPH)
  • Slide 6
  • Project Types and Scoring Guides Model a scaled replication of a device or product. Collection - a group of objects or results that form some type of pattern Invention - a new way of making something or performing an action Experiment - a problem that is investigated by performing a series of tests in which one thing is changed each time and all other things remain the same from test to test. Observation - a series of events that you watch and try to explain and find common connections or occurrences
  • Slide 7
  • Sample Experiment Project Twirlybirds
  • Slide 8
  • Question Does adding mass affect the time it takes a twirly bird to get to the ground? How does adding mass affect the time a twirly bird takes to get to the ground?
  • Slide 9
  • Background Why project is important to you and/or society History of Science behind Advancements in Scientists involved with Bibliography (3-5 only) 3 sources
  • Slide 10
  • Hypothesis hypothesis vs. prediction What color shirt will Bobby wear tomorrow? prediction If I put a drop of water on a slope, then it will flow downhill. hypothesis
  • Slide 11
  • Twirly Bird Hypothesis If we add mass (large paper clips) to the twirly bird, then
  • Slide 12
  • Variables Independent Variable: the variable you are changing in the experiment Number of Large Paper Clips (0, 1, and 2) Dependent Variable: what you are measuring (in metric) Time until it hits the ground (seconds) Constants: twirly bird, size of paper clips, drop height, stopwatch, location, direction and angle of wings, placement of paper clips
  • Slide 13
  • Control The basic with which all other things are compared. Note not all experiments have a control. Example: Question: How does the salinity of water affect the growth of bean plants? Control distilled water. Our Control the standard twirly bird with 0 paper clips
  • Slide 14
  • Safety Guidelines: All safety procedures need to be recorded in your logbook. A signed safety form must be included on the inside cover of your logbook. No animal (this includes invertebrates) should be harmed or caused pain. Safety gloves should be used for any testing with food or chemicals. EYE PROTECTION: Safety glasses should be used for any experiments with chemicals or if any kind of splash may come in contact with your eyes ALLERGIES: Remember human subjects may be allergic to different substances. Always ask about allergies. FIRE: Projects are not allowed that involve fire or burning objects.
  • Slide 15
  • Safety (cont.) HUMANS: No experiments should be done on humans that can cause any potential harm to the human. Exceptions include observational type studies such as food tasting, observing, thinking type exercises, etc. Bottom lineit is ok as long as there is no possible way that any person can be harmed. BACTERIA: Due to the potential for inhaling or coming in contact with harmful bacteria, students should avoid projects where they collect bacteria and then grow bacteria cultures. While this can be done safely, the potential exists for a very harmful pathogen to be inhaled or come in contact with the student. OTHER: No experiments should be done using firearms. Experiments cannot include prescription drugs, illegal drugs or alcohol.
  • Slide 16
  • Procedure - Practice, practice, practice. - Materials & Methods - Step-by-Step - Diagrams/Photographs (no faces should be included in the photographs) - Begin each step with a verb and write them as commands.
  • Slide 17
  • Materials Be specific about how many, what size, etc. 1 Standard Twirly Bird 2 large paper clips 1 stopwatch 1 meter stick
  • Slide 18
  • Twirly Bird Procedure 1.Make a standard twirly bird. 2.Hold the twirly bird 2m from the floor. 3.Let go and time how long it takes the twirly bird to get to the floor. 4.Record your data. 5.Repeat steps 2-4 two additional times.
  • Slide 19
  • Procedure (cont.) 6.Add one large paper clip to the bottom of the twirly bird (see picture). 7. Repeat steps 2-5 three times. 8. Repeat steps 2-5 using two large paper clips on the bottom of the twirly bird.

  • Data Table Dependent Variable Label Independent Variable Label Trial 1Trial 2Trial 3Average Sample 1 Sample 2 Sample 3 Be sure to average your data. Data Table Title
  • Slide 21
  • Twirly Bird Data Table Time Until Hitting the Ground (seconds) Number of Paper Clips Trial 1Trial 2Trial 3Average 0 paper clips 1 paper clip 2 paper clips The Effect of Adding Mass to a Twirly Bird
  • Slide 22
  • Graph Line graphs should be used to show change over time or a change made to the same system. Bar graphs should be used to show isolated incidents. Only your average should be graphed. Type a sentence explaining the results of your data.
  • Slide 23
  • Twirly Bird Graph Number of Paper Clips The Effect of Adding Mass to a Twirly Bird Time Until Hitting the Ground (seconds) Sentence explaining the results.
  • Slide 24
  • Conclusion Be sure to relate your conclusion to your original question and hypothesis and include specific data. Claim: The statement you believe to be true. Evidence: The specific evidence that supports your claim.
  • Slide 25
  • Twirly Bird Conclusion I thought that as the mass of the twirly bird increased (as we added paper clips), the time it would take to hit the ground would decrease. My experiment supports my hypothesis. When we used the standard twirly bird with no paper clips, the twirly bird took an average of _____ seconds to reach the ground. With one paper clip added, the twirly bird took an average of ____ seconds to reach the ground. The twirly bird took an average _____ seconds to reach the ground with two paper clips.
  • Slide 26
  • Conclusion (cont.) My results agreed with what I found in my research
  • Slide 27
  • Scientific Worth/Future Studies Explain how you know your results are valid and reliable. Describe how you might improve your project if you could do it again. Include ideas for what related questions you might now go on to explore. Discuss the value of the information learned and how this could impact your life.
  • Slide 28
  • Twirly Bird Scientific Worth and Future Study I feel confident that my results are reliable. I completed three trials getting similar results each time. Even so, there is room for improvement. It was difficult to let go of the twirly bird and start the timer at the same time. If I were to do this experiment again I would try to find a better way to make sure they were happening at the same time.
  • Slide 29
  • Scientific Worth/Future Studies (cont.) This investigation was important for people who might need to drop items from helicopters after natural disasters or in areas of war. If they put too much weight on a parachute it might affect the drag, which would make it fall too fast. While I was completing this investigation I wondered what would happen if I changed the size of the twirly bird wings. This might be something I would like to study in the future.
  • Slide 30
  • Display Follow the given layout as close as possible as a common courtesy. No identifiable photographs. Use photographs to represent real things the real things need not be displayed on the board. Dont go overboard!
  • Slide 31
  • Let the projects begin!
