Presentation Transcript

  1. Warm-up • Copy the objective • Sequence the steps listed below. Use the textbook for a reference if necessary. • Communicate results • Develop a question • Perform research • Test hypothesis • Create hypothesis • Analyze results

  2. What’s wrong with these questions? What does that thingy do? How do I do this? How does texting effect it? How do you find out what happens?

  3. Warm-up Explain why the Scientific Process should not be considered a step-by-step checklist.

  4. Questions about questions Why is it important to ask “GOOD” questions? What makes a good question?

  5. FORMULATING QUESTIONS • To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science. Albert Einstein WHO, WHAT, WHERE, WHEN, WHY, HOW, DOES

  6. Objective Create and evaluate scientific questions

  7. Testable questions Why must scientists ask testable questions?

  8. Testable questions Testable Not testable What is the meaning of life? How long am I going to live? Is my goldfish happy? • How do North’s 2012 math TCAP scores of compare to those of 2011? • What percentage of trees in Colorado Springs are conifers? • How does the temperature of water effect the amount of sugar that can be dissolved?

  9. Check for understanding Choose a topic Develop two testable questions and one untestable question regarding the topic.

  10. Characteristics of good questions Successful people ask better questions, and as a result, they get better answers. (Tony Robbins) • Purposeful • Does the question have meaning? • Logical • Does the question make sense? • Understandable • Does the question use proper grammar? • Specific • Does the question have details and key words?

  11. Writing scientific questions… Don’t Do Key words Appropriate vocabulary Proper grammar Precise wording • It • Thing • You • Poor grammar • Confusing wording

  12. What is Selena’s question? • Selena is doing a science fair project for her school. For her experiment, she gathered 10 pots and placed 5 seeds in each. She then added the same soil to each pot and made sure that each pot received the same amount of water and sunlight. However, half of the pots also received a weekly dose of fertilizer.

  13. What is Rahmel’s testable question? • Rahmel is conducting research on the Internet. After visiting several reliable websites he learns about what is needed to support life. After further research, he finds that Europa, a moon of Jupiter, has an atmosphere and contains surface ice, perhaps with liquid water underneath.

  14. What is Julio’s question? Julio gives a questionnaire to 50 different students at Carmel Middle School. After looking at the results of the questionnaire, Julio determines that approximately 45% of Carmel students have Internet access at home.

  15. What is Samuel’s question? Samuel sets up three different aquariums with different temperature water. He places a goldfish in one aquarium and allows it to sit for 5 minutes. Next, he counts how many times the fish breathes in 1 minute. He repeats his procedure with the other two aquariums.

  16. Mythbusters What is the question (myth)? • MacGyver Myth - Light bulb and Drain Cleaner • Drowning Cockroaches • Plane on Conveyor Belt

  17. More vids Banana peels Parachute Car Jet Stream Taxi Tree and Machine Gun Texting and Driving

  18. Evaluating Questions • Scoring scale • 5 – excellent, testable, PLUS, critical thinking • 4 – good, PLUS, testable • 3 – average, testable, missing one PLUS • 2 – below average, testable, missing multiple PLUS • 1 – poor, not testable, confusing • 0 – off topic

  19. Examples How does rolling a ball compare to speed? How does the speed of a ball change when rolled on different surfaces? What effect does friction have as a ball rolls down a ramp made from different types of surfaces?

  20. Testable Questions Cell phone Video games Exercise Plants Dog behavior

  21. Evaluating questions • Cell phone • Video games • Exercise • Plants • Alternative energy • Global warming

  22. DOL (part I) Write a scientific question for one of the topics below. • Air pollution • Gravity • Immigration • Scoring scale • 5 – excellent, testable, PLUS, critical thinking • 4 – good, PLUS, testable • 3 – average, testable, missing one PLUS • 2 – below average, testable, missing more than one PLUS • 1 – poor, not testable, confusing • 0 – off topic

  23. DOL (part II)Evaluate the questions • Car and Driver recently published an article regarding texting while driving. They had people drive at the same speed while texting and not texting. Each driver was asked to stop as quickly as possible after a light flashed on the dashboard. Car and Driver then measured the average stopping distance for each person. • How long is the delay while texting compare to not? • If a person is texting while driving, does he or she have any loss in motor control, and stopping when suddenly told to do so, and not texting? • How does texting while driving effect how quickly someone can react and stop?

  24. DOL (part III) Write a scientific question Wolves
