  1. The Helicopter Hypothesis A lesson in scientific inquiry

  2. Teacher’s Notes, page 1 • Background: • Students should already know how to identify and use observation, inference, and prediction. • Students should be familiar with Cornell note strategies. • This introductory lesson will be accompanied by a laboratory experiment and data analysis.

  3. Teacher’s Notes, page 2 • Action Steps incorporated into this lesson: • Identification of critical-input experiences • Presentation of information in small chunks with room for student input • Student-written conclusion (in Cornell format) • Student reflection of learning

  4. Teacher’s Notes, page 3 Continued • Action Steps incorporated into this lesson: • Providing students with opportunities to practice learning • Use of games focused on academic content • Incorporation of unusual information

  5. Student Lesson begins on next slide

  8. Objective • Students will be able to: • Define/explain several important terms used in scientific inquiry • Apply these terms in a real-life scientific inquiry challenge

  9. Brainbuster! What is the only bird that can fly both forwards and backwards?

  10. Brainbuster! Answer: the hummingbird

  11. paper helicopter of science! hummingbird helicopter

  12. Today’s Important Terms:  Scientific Inquiry Hypothesis Control Group Independent Variable Dependent Variable Uncontrolled Variable

  13. What is Scientific Inquiry? • It is the process of using observations, inferences, predictions and experiments to learn about the world • It is an ongoing process of discovery • It is used in all types of science, but also in other areas, and even regular daily life!

  14. Example: Scientific Inquiry Uh oh! I turn on my radio, but no music comes out. observation conclusion The plug isn’t my problem. Something else must be wrong. Maybe the radio is unplugged? inference If the radio is unplugged, then plugging it in will start the music. Yep, the plug is plugged in. data analysis I’ll check and see if the plug is plugged into the wall. prediction experiment

  15. Example: Scientific Inquiry Uh oh! I turn on my radio, but no music comes out. The plug isn’t my problem. Something else must be wrong. Maybe the radio is unplugged? hypothesis If the radio is unplugged, then plugging it in will start the music. Yep, the plug is plugged in. I’ll check and see if the plug is plugged into the wall. prediction

  16. Today’s Important Terms: Scientific Inquiry  Hypothesis Control Group Independent Variable Dependent Variable Uncontrolled Variable

  17. What is a Hypothesis? • It is a prediction • It is almost always based on observations and inferences • It is testable • It is my best guess of what will happen

  18. Today’s Important Terms: Scientific Inquiry Hypothesis  Control Group Independent Variable Dependent Variable Uncontrolled Variable

  19. What is a Control Group? • It is the unchanged (“normal”) stuff in an experiment where I am testing different conditions • It is something to which I can compare my test results • It’s sometimes just called a control Control = Comparison

  20. Today’s Important Terms: Scientific Inquiry Hypothesis Control Group  Independent Variable Dependent Variable Uncontrolled Variable

  21. What is an Independent Variable? • It is the condition I change in an experiment • I change it because I want to see what will happen • I should change only one thing at a time • I’m in charge of it! Independent Variable = I change it

  22. Today’s Important Terms: Scientific Inquiry Hypothesis Control Group Independent Variable  Dependent Variable Uncontrolled Variable

  23. What is a Dependent Variable? • It is the data I collect • It is the observation I make after testing my independent variable • It is the result of my experiment • It depends on what I changed Dependent Variable = Data that Depends

  24. Today’s Important Terms: Scientific Inquiry Hypothesis Control Group Independent Variable Dependent Variable  Uncontrolled Variable

  25. What is an Uncontrolled Variable? • It is a source of error • It is an unexpected mistake or event in my experiment • It may be unavoidable • It may make my data unreliable • It is generally unwanted! Uncontrolled Variable = Unexpected, Unreliable

  26. Quick Quiz

  27. What do you call a prediction, or educated guess? Scientific Inquiry  Hypothesis Control Group Independent Variable Dependent Variable Uncontrolled Variable

  28. What is the thing that I change in an experiment? Scientific Inquiry Hypothesis Control Group  Independent Variable Dependent Variable Uncontrolled Variable

  29. What is the thing that remains unchanged in an experiment? Scientific Inquiry Hypothesis  Control Group Independent Variable Dependent Variable Uncontrolled Variable

  30. What do you call the data that you collect in an experiment? Scientific Inquiry Hypothesis Control Group Independent Variable  Dependent Variable Uncontrolled Variable

  31. What do you call the things that may cause errors in your experiment? Scientific Inquiry Hypothesis Control Group Independent Variable Dependent Variable  Uncontrolled Variable

  32. What do you call the process of doing experiments to learn answers?  Scientific Inquiry Hypothesis Control Group Independent Variable Dependent Variable Uncontrolled Variable

  33. The Helicopter Hypothesis • To practice using all these parts of scientific inquiry, you will build and test paper helicopters • Your goal is to figure out what will make them stay in the air the longest

  34. The Helicopter Hypothesis A regular helicopter  Control Group What I change  Independent Variable What I think will happen  Hypothesis What actually happens  Dependent Variable Possible mistakes  Uncontrolled Variable The entire experiment  Scientific Inquiry

  35. The Helicopter Hypothesis • In your next lessons, you will perform the experiment and examine your data • You’ll learn more about scientific inquiry by really using it!

  36. Objective • Students will be able to: • Define/explain several important terms used in scientific inquiry • Apply these terms in a real-life scientific inquiry challenge
