Scientific inquiry part 1

  1. 1. Scientific Inquiry Today we will fill in notes on: 1) Questions 2) Independent Variable 3) Dependent Variable Notes Directions: 1) In your binder, title a fresh page of notes and date the notes. 2) Add a line in your table of contents called “Scientific Inquiry Notes”. Don’t forget a page number!
  2. 2. Scientific Inquiry (take these notes in your three ring binder…we’ll go to our organizers later. • A process scientists use to study the world and create explanations based on evidence. • Let’s make a list on how we can use scientific thinking in our everyday life:
  3. 3. Pose a Question Write a Hypothesis Design Experiment Collect Data Draw a conclusion Communicate Findings It’s a never ending cycle in how we think! Sometimes, by doing the experiment we come up with another question and the process continues.
  4. 4. Pose a Question (OK – Start filling in your organizer!) • Based on observations and answered by gathering data. – NOT based on opinion. • Which question below is scientific? – Why has my CD player stopped working? – What kind of music should I listen to on my CD player?
  5. 5. Variables • In science, variables are what you interested in. • Based on your question. • Two Types: – Independent Variable: The variable that is tested. (abbreviation: IV) • Controlled by the experimenter
  6. 6. Independent Variables • Example: A student wanted to know if crickets chirped more at higher temperatures. They did an experiment where they placed a crickets in a three habitats at different temperatures and counted the number of chirps. – IV  Temperature • BECAUSE it is what’s tested (Temperatures AFFECT ON chirps). • BECAUSE it’s controlled by the experimenter.
  7. 7. Dependent Variable  Dependent Variable: The factor that is measured. “Depends” on the independent variable. (Abbreviation: DV)  NOT controlled by the experimenter
  8. 8. Dependent Variable • Example: (see story under independent variable tab.) – A student wanted to know if crickets chirped more at higher temperatures. They did an experiment where they placed a crickets in a three habitats at different temperatures and counted the number of chirps. • DV  Number of Chirps – BECAUSE it is measured (counted) – BECAUSE it is not controlled by the experimenter
  9. 9. PRACTICE: with your group, decide which is the IV and which the DV and write your answers on the white board. – You wonder which dissolves first in water; sugar or salt. To answer your question, you design an experiment where you put sugar in water in one cup and salt in water in another cup. Then you time how long it takes each substance to dissolve. • IV  • DV 
  10. 10. PRACTICE: with your group, decide which is the IV and which the DV and write your answers on the white board. • You work for Hasbro making children’s toys. You wonder which color ball babies prefer. You design an experiment where you place three balls in a room. Each ball is a different color. Using baby volunteers, you record which color ball babies crawl to first most often. – IV  – DV 
  11. 11. PRACTICE: with your group, decide which is the IV and which the DV and write your answers on the white board. • An aerospace engineer (someone who builds airplanes) is interested in redesigning the airplane to make them more fuel efficient. She creates three possible designs and tests them to see which is the most fuel efficient. – IV  – DV 
  12. 12. • GLUE YOUR FLIP BOOK ONTO THE BACK SIDE OF YOUR NOTES.
  13. 13. Homework • Draw an illustration under the three tabs we did today that will help you remember the meaning of each word. – Questions, IV, and DV.
