  1. Any Questions? Creating testable questions out of observations

  2. ILO/Language Objective • Science ILO 1: Use science process and thinking skills. • e. When given a problem, plan and conduct experiments in which they: • Form questions • Discuss possible outcomes of investigations • Identify variables • Plan procedures to control variables • Summarize and analyze data • Report findings of investigation

  3. Overview • Engage: Making observations • Explore: Comparing observations with others, making new observations. • Explain: Discussion about what makes a good observation. • Explore/Explain Cont’:Additional observation activity • Elaborate/Evaluate: Turing observations into questions • Evaluate: Using the 4 question strategy to using questions in experimental design.

  4. Objects to Observe: What questions do you hear? • Listen to the story, write down the questions that the scientists had. Add your own questions if you have any. • Come and select an object that interests you-record observations on the T-chart. • Compare your observations with a partner with the same object. • Find a new object and write observations. • Compare your observations with the ones on the sheet below it.

  5. Explain • At your table group, discuss the following: • What did you observe? • What did you like about the objects? • Explain one of the neatest things about your object. • What makes a good observation? • Discuss as a group and identify a spokesperson to share your group’s ideas.

  6. Explore/Explain • Take out your own interesting object and record observations about it on the T chart. • Teacher will collect the observations and give them to someone else—you will try to identify the object based on the observations.

  7. Elaborate/Evaluate • Modeling: Observations into Questions • Take a look at the very interesting object that the teacher has brought. • As a class, record observations on the board • How can we turn the observations into questions? As a class, turn those observations into questions.

  8. Student Practice • Using the observations from the first 2 objects observed, students should create as many questions as they can on the T-chart.

  9. Question sorting • Model • Use the Picture Perfect chapter on questions. • Give each group a set of questions about the large object. Sort together. • In your notebook, make a t-chart • Investigable vs. Research • Sort student questions from object #1.

  10. 4 question planning • 1. What materials are readily available for conducting experiments on _________? • 2. How do(es) __________ act? • 3. How canyouchange the set of ________ materials to affect the action? (Independent - changeit!) • 4. How canyoumeasureordescribe the response of __________ to the change(Dependent - It changed!)

  11. How to Write a Testable Question Tamara Helfer, 2012 Sequoia Science Explorations

  12. Sometimes scientists just like to explore…

  13. Exploring or making observations often makes scientists curious about specific questions. To answer these questions, most scientists carry out investigations

  14. What is a “Testable Question?” A testable question is one that can be answered by designing and conducting an experiment.

  15. Testable questions are always about changing one thing to see what the effect is on another thing. What is a “Testable Question?”

  16. Sample Testable Question Does changing the height of the ramp affect the speed of a car going down the ramp?

  17. In a scientific experiment, these two blanks have special names: variables Testable Question Formats • Does changing _______ affect _______? • How does changing _____ affect _____? • If I change ______, will it affect ______?

  18. What is a variable? A variable is something that can CHANGE.

  19. Testable Questions have two parts: • An independent variable • A dependent variable

  20. What is anIndependent Variable? • The variable that will be changed by you – the scientist. A good experiment has only one independent variable!

  21. What is aDependent Variable? • The variable that is being measured in your experiment • The response to the change you make using the independent variable.

  22. Testable Question Formats independent variable dependent variable independent variable dependent variable independent variable dependent variable • Does changing _______ affect _______? • How does changing _____ affect _____? • If I change ______ will it affect ______?

  23. Example: Does changing the height of the ramp affect the speed of the car going down the ramp?

  24. What is the independent variable? Does changing the height of the ramp affect the speed of the car going down the ramp?

  25. Independent Variable Does changing the height of the ramp affect the speed of the car going down the ramp?

  26. What is the dependent variable? Does changing the height of the ramp affect the speed of the car going down the ramp?

  27. Dependent Variable Does changing the height of the ramp affect the speed of the car going down the ramp?

  28. Review: Testable Questions Testable Questions need 2 parts: • Independent variable • Dependent variable

  29. Is this a Testable Question? What makes plants grow best?

  30. How to Turn a General Question into a Testable Question First, read the question carefully. What makes plants grow best?

  31. How to Turn a General Question into a Testable Question Next, think of a cause and an effect related to your question. What makes plants grow best? In this case, the idea is that you can change something to affect something about how a plant grows.

  32. What makes plants grow best? What are examples of things you can change?

  33. What makes plants grow best? Examples: -Amount of water -Amount of light -Soil type What are examples of things you can change?

  34. What makes plants grow best? What specific effects can you look for?

  35. What makes plants grow best? Examples: -Height of plant -Speed of growth What specific effects can you look for?

  36. Finally, plug the cause and the effect into the format… “What is the effect of ____ on ____?” The cause goes in the first blank, and the effect goes in the second blank. So a testable question looks like this: “What is the effect of soil type on plant height?”

  37. Controls Controls are all the factors in your experiment that you want to remain constant. “What is the effect of soil type on plant height?” Controls for the plant experiment: • type of plant • growing conditions (sunlight, temperature, etc.) • amount of water • type of container
