  1. Science Fair Due dates and guide lines

  2. Dates • September: • 21st : Reference sheet with 5 sources based on APA formatting • 28th : Experimental design sheet (can be turned in sooner) • October: • Experiments and another research needs to be done by the end of October • November: • 1st-2nd: Data Results should be brought to class! Writing in science (third person) voice- Materials and methods, data/Results/Analysis sections written in class with peer feedback • 14th Peer review of research paper (must have your paper completely written!!!) • 16th : 1st paper revision due • 19-20th : corrected papers handed back • 30th : Final paper due

  3. Dates Continue • December • 3rd-4th : final papers handed back • 7th: peer review of science boards. You need to have a paper copy of how you are going to do your science board • 14th: Science boards due. • 19th: Science Fair @ SOJH • (A-L) 6-7 pm • (M-Z) 7-8 • Judges Training 5:30 pm • January 4th: Science Fair Registration Due • Not every student will be invited to the district science fair, we will select those who advance from the participants of the SOJH Science Fair. • January 24th : Junior High Science Fair • January 25th: Senior High Science Fair

  4. Guide Lines/Rules • Must work with a partner in this class • Question must be something you are VERY interested in! • This is not a demonstration. Anything built should be for the purpose of testing your hypothesis. • No elementary volcanos, experiments should have a dependent, independent, and control variables. • Animal cruelty will not be tolerated

  5. Variables

  6. Experiments • cause and effect relationships in nature • Way of knowing how nature works by changing one variable and predicting how it will effect other variable. • Variables: a factor, trait, or condition that can happen in differing amounts or types

  7. Types of Variables • Control: • Remain constant/ stays the same • Used to compare how something has changed • Independent: • variable that is changed by scientists • Only change one thing at a time for best results • Dependent: • May change due to the independent variable • Response variable

  8. Classifying Variable Type Examples • A student wants to know “Does heating a cup of water allow it to dissolve more sugar?” In preforming his experiment he uses the same type of sugar and amount of sugar for each test. He also puts the same amount of water into the cup each time. He changes the temperature of the water in the cup and observes the dissolving of the sugar to answer his question. • What is the independent variable? • temperature • What is the dependent variable? • Amount of sugar dissolved • What are the controlled variables? • Type of sugar, amount of water, cup, etc…

  9. Classifying Variable Type Examples • A student wants to know: “Does fertilizer make a plant grow bigger?” The student gathers pots, fertilizers, plant, soil of the same type to prepare for her experiment. She then plants her plants in the pots and makes sure that each gets the same amount of water and light for a given amount of time. She then varies how much fertilizer each of her plants gets. She observes her plants over the next few weeks measuring their height and number of leaves. • What is the dependent variable? • Height and number of leaves • What is the independent variable? • Amount of fertilizer • What are the controlled variables? • Fertilizer type, pot size, plant, soil type, water and light amount, etc…

  10. Classifying Variable Type Examples • Your teacher wanted to know: “Would the amount of eggs in a chocolate chip cookie recipe change the height of a cookie?” She then went to the store and bought the ingredients for her experiment. She kept all the ingredients the same, but for each batch she made she changed the number of eggs she put in. She also kept the oven temperature the same. When the cookies came out of the oven, she would measure the cookies with a toothpick by sticking it in the middle and marking it at eye level. She then measure the toothpick with a ruler. • What is the independent variable? • Amount of eggs • What is the dependent variable? • Height of the cookies • What are the controlled variables? • The ingredients, oven temperature, measuring the cookies in the middle, etc…
