    Presentation Transcript
    1. Tuesday Sept 4th or Weds Sept 5th • Please write the underlined words in your planners

    2. How do you think you did on the Safety Quiz? • 1st Hour: 96.7% • 2nd Hour: 97.8% • 3rd Hour: 92.2% • 4th Hour: 96.7% • 6th Hour: 92.2% • 7th Hour: 94.4%

    3. Add Safety Quiz and BOY Exam to your folder • Complete the Quiz and Test Tracker for the BOY exam and the Safety Quiz • Put the BOY exam and Safety Quiz in the prongs of your folder

    4. September 4th Remember to write the questions and your answers in your lab book. Do Now: • What do you think the scientific method is? • Why do scientists have experiments?

    5. When we take notes, please write down all the red words. • If it’s not in red, you probably don’t need to write it.

    6. What is the scientific method? • Scientific Method: the way scientists solve problems and make experiments

    7. What can we use the scientific method for? • We can use it to conduct experiments, learn new information, and solve problems.

    8. Why is the scientific method important to you? • You will use it all year in every one of your labs. • You will need to know the scientific method for all of your science classes in the future. • You will need to know and use the scientific method when you create your own experiment at the end of the year.

    9. Steps of the Scientific Method Steps of the Scientific Method • Make an observation and ask a question about it. • Research if needed • Make a hypothesis • Test the hypothesis in an experiment • Record and analyze the data • Write a conclusion to share your results

    10. Scientific Method in Your Life • Make an observation and ask a question about it. • Research if needed • Make a hypothesis • Test the hypothesis in an experiment • Record and analyze the data • Write a conclusion to share your results • My room is dirty. Will my mom notice if I don’t clean my room? • Last time I didn’t clean my room, my mom saw all my clothes on the floor. • If I pick up my clothes, then my mom won’t notice that the rest of the room isn’t clean. • I picked up my clothes and she didn’t notice that it was dirty. • … • …

    11. Now use the SM on the scenario you are given about Lil Wayne

    12. Steps of the Scientific Method Make an observation and ask a question Research Make a hypothesis Test the hypothesis in an experiment Record and analyze the data Write a conclusion to share the results

    13. Independent and Dependent Variables • Understanding IV and DV is very important for understanding the scientific method. • Do you know what an independent variable is? • Do you know what a dependent variable is?

    14. Independent and Dependent Variables • Independent variable: This is what you change in an experiment. • Dependent variable: This is what you measure in an experiment.

    15. To identify the IV and the DV: • Ask yourself what is being changed? (IV) • Ask yourself what is being measured? (DV)

    16. What is the IV and DV? Independent variable: how much light the plant gets. Dependent variable: how tall the plant grows

    17. What is the IV and DV? • Studying a lot and improving your grades IV: how much you study DV: Your grades

    18. What is the IV and the DV? • Marco wanted to know if sleeping 9 hours every night makes people have more positive attitudes. DV: positive attitudes IV: amount of sleep

    19. What is the IV and DV? • Will you grow taller if you drink more milk? IV: how much milk you drink DV: how tall you grow

    20. What is the IV and DV? • Do people run faster with Nikes or Jordans? IV: Type of shoe DV: how fast people run

    21. Add the red words to your glossary • Remember to add the word and the page number • You do not need to write the definition in the glossary • Scientific method • Independent variable • Dependent variable

    22. IV and DV Stations On the same pages as your do now and notes, please number from 1 to 10, skipping two or three lines between each number. Label IV and DV like below. • IV: DV: 2. IV: DV:

    23. IV and DV Stations • You will be going to stations around the room with your tablemates. For each station you will see a scientific question. Your job is to work together and identify the IV and DV and record it in your lab book. • Make sure you are recording each station number at the correct spot in your lab book.

    24. Complete “Scientific Questions and Variables” worksheet as homework Homework is due next time you have this class.

    25. Thursday Sept 6 or Friday Sept 7 • Remember to write the questions and your answers in your lab book. • Do Now: • 1. Why is the scientific method important? • 2. How can you tell independent and dependent variables apart? Get homework out and keep it on your desk.

    26. Go over homework answers together

    27. Scientific Questions • A good scientific question needs: • An independent variable • A dependent variable • To be measureable • heavier, taller, faster, increased • NOT prettier, better, healthier

    28. Scientific Questions • Example: Will the amount of sunlight a plant receives affect how tall the plant grows? • Why is this a good example? What’s the IV? What’s the DV? Is it measureable?

    29. Scientific Questions • Does more acidic soil cause plants to grow fewer leaves? • Why is this a good example? What’s the IV? What’s the DV? Is it measureable?

    30. Scientific Questions • Do Jordans or Nikes make you run faster? • Why is this a good example? What’s the IV? What’s the DV? Is it measureable?

    31. Scientific Questions • How many miles are between Oklahoma City and Tulsa? • Why is this a bad example? What’s the IV? What’s the DV? Is it measureable?

    32. Scientific Questions • Should I cut my hair? • Why is this a bad example? What’s the IV? What’s the DV? Is it measureable?

    33. Scientific Questions • Does wearing makeup make you prettier? • Why is this a bad example? What’s the IV? What’s the DV? Is it measureable? How can we make it better?

    34. Scientific Questions • Does eating breakfast make you better at catching a baseball? • Why is this a bad example? What’s the IV? What’s the DV? Is it measureable? How can we make it better?

    35. Scientific Questions • With your group, write a list of three GOOD scientific questions. • Make sure they are measureable and have an IV and DV

    36. Hypotheses • A hypothesis is an educated guess. It’s like a prediction. • It is an If/then statement • It is always in this format: “If (independent variable) then (dependent variable). • Example: If you play violent video games, then you will have higher blood pressure.

    37. Hypotheses • How to turn a scientific question into a hypothesis: • 1st identify the IV and DV • 2nd think about your prediction • 3rd begin with “If” and the IV • 4th finish it with “then” and the DV

    38. Hypotheses • Do Jordans or Nikes make you run faster? • IV: type of shoe (Nikes or Jordans) • DV: how fast you run • My prediction: I think that Nikes will help you be faster. • Hypothesis: If you wear Nikes, then you will run faster.

    39. Hypotheses • Does a plant grow taller when it is given more water? • IV: how much water it gets • DV: how tall the plant grows • My prediction: I think that plants given more water will grow taller. • Hypothesis: If a plant gets more water, then it will grow taller.

    40. Hypotheses • Does eating breakfast lead to higher test scores? • IV: eating breakfast • DV: test scores • My prediction: I think that eating breakfast will lead to higher test scores. • Hypothesis: If you eat breakfast, then you will earn higher test scores.

    41. Add the red words to your glossary • Remember to add the word and the page number • You do not need to write the definition in the glossary • Scientific question • Hypothesis

    42. Hypothesis Stations • On the same page as your do now and your notes, please number from 1 to ___, skipping two or three lines between numbers.

    43. Hypothesis Stations • You will be going to stations around the room with your tablemates. For each station you will see a scientific question. Your job is to work together to write a hypothesis for each scientific question. • Make sure you are recording each station number at the correct spot in your lab book.

    44. Exit Slip • Label your note card with your FIRST AND LAST NAME, DATE, and HOUR. Labeling this correctly is worth one point. First and Last Name Date Hour 1. 2. 3. 4. 5.

    45. Exit Slip • Clear everything off of your table. Close lab books and put them on the floor. • NO TALKING, at all. If you have a question raise your hand SILENTLY and wait for the teacher. • If it is multiple choice, you can just write the letter of the answer.

    46. Question 1 • What makes a good scientific question? • It is measureable. • It has a dependent variable • It has an independent variable • All of the above

    47. Question 2 • What is an independent variable? • What is measured in an experiment • What is changed in an experiment • An educated guess • What is always kept the same in an experiment

    48. Question 3 • What is the dependentvariable in this scientific question?: “Do Jordans or Nikes make you run faster?” • Type of shoe • How fast you run • If I wear Jordans, then I will run faster. • The track you run on

    49. Question 4 • What is the best written hypothesis for this scientific question? “Do Jordans or Nikes make you run faster?” • Wearing Nikes makes you run faster. • If I run faster, then I’m wearing Nikes. • If I wear Nikes, then I will run faster. • If I wear Nikes I’m going to run faster.
