  1. Good Morning/Afternoon • Have out your USB, Science Fair Folder & journal • Agenda • Review Problem, Hypothesis & Variables • Chromebook rules • Research, begin typing

  2. An example of a Science Fair Project • Scientific Method • Variables-independent, dependent, control, constant

  3. 1. 0bservation Juan watches his grandmother baking bread. He asks her what makes the bread rise. She explains that one ingredient, yeast, releases a gas as it feeds on sugar.

  4. 2. Problem/Question Juan wonders if… the amount of sugar used in the recipe would affect the size of the bread loaf.

  5. Research: Review of Literature Juan researches about baking and fermentation and tries to come up with a way to test his question. He keeps all of his information on this topic in a journal.

  6. Hypothesis-an educated guess Juan comes up with a the following hypothesis. “If more sugar is added to the recipe, then the bread will rise higher.”

  7. Independent Variable(cause)- It is the condition intentionally changed by the reseacher. In this case: the amount of sugar. Juan is going to use 50 g, 60 g and 70 g of sugar in his experiment.

  8. Dependent Variable(effect) It is the factor that may change as a result of changes in the independent variable. In this case: the size of the loaf of bread.

  9. Control It is the condition that serves to compare, the normal condition. (compara el condicion de lo demas materiales o objetos del experimento) Because Juan’s grandmother always uses 50g. of sugar in her recipe, Juan decided to use the bread made with that amount of sugar as his control group.

  10. Constant The constants in an experiment are all the factors that the experimenter tries to keep the same. (cosas en el experimento que dejas igual, no cambia)

  11. Can you think of some constants for this experiment?

  12. Constants They might include: • other ingredients to the bread recipe • oven used • rise time • brand of ingredients • cooking time • type of pan used • oven temperature • age of the yeast…

  13. Size of Baked Bread (LxWxH) cm3 Size of Bread Loaf (cm3) Trials Control group

  14. Conclusion-explain results, use data Explicar resultados y informacion que usaste Juan finds that 70g. of sugar produces the largest loaf. His hypothesis was supported by the experiment!

  15. Science Fair Project • 1.Problem/Question-write the question about your project • 2.Hypothesis- what do you predict will happen in your experiment based on your question • 3.Variables • Independent- • Dependent- • Control- • Constant-

  16. Science Fair Due by 9/28 • Problem/Question • Hypothesis- what is your prediction? what will happen in your experiment? ( research first) • Variables- Independent, Dependent, Control, Constant

  17. Research • Research information regarding your problem/question in order to create a correct hypothesis • Use science buddies • Cps science fair. Org • Google- search engine • NO WIKIPEDIA- not a reliable source

  18. Chrome book Rules • 1. Each student will have their own # chrome book, that # will be the same all year. • 2. Each class you use the chrome books you use the same # • 3. If there is a problem with the chrome book or something happens to it, please let the Teacher know IMMEDIATELY.

  19. Rules • 4. Use the chrome book for your assignment only • 5. Don’t go on other websites your not advised to follow • 6. Don’t check your grades • 7. Don’t email other classmates • If you chose to not use the technology properly, your privilege will be taken away for the remainder of the year.
