19. HOW TO MAKE IT!

20. CH 1 NOTES #2 9/11 SCIENTIFIC METHOD

21. Scientific Method -A series of steps used to solve a problem

22. STEPS: 1.STATE THE PROBLEM EXAMPLES: Why do leaves fall off in the fall? What does a medicine do to the body? Why does our eyes get goo in the corners in the morning? Does popcorn pop better when cold?

23. 2.GATHER INFORMATION (research) Read about what you want to learn about and research what people already know to help you come up with ideas or experiments; make observations about something you want to study FOR POPCORN?

24. 3.FORM A HYPOTHESIS – an educated guess * If …… then …… A guess of what you think the answer to your question is after doing research. Your hypothesis may be right, it may be wrong. FOR POPCORN…?

25. WHAT WERE THE 1 st 3 STEPS????

26. 4.CONDUCT AN EXPERIMENT Need : - to get materials - to follow a procedure - to make observations - to collect data Darwin spent nearly 20 years analyzing the data he collected came up with his conclusions! FOR POPCORN?

27. KEEP TRACK OF OBSERVATIONS DATA What data would you keep of during the experiment?

28. Experiment vocabulary Control group – group not having anything changed - used to compare Experimental group – group that you made some change to

29. You wanted to find out if mice behave differently if you give them caffeine Experimental Group? Control Group?

30. 1 2 1

31. Can have many experimental groups http://www.youtube.com/watch?v=VhZyXmgI FAo

32. Should you just do one of each?

33. Constant – things that stay the same between the groups FOR POPCORN? - same amount/ size bag of popcorn - same time - same brand - same place in the microwave ROOM TEMP COLD TEMP

34. * you only want to change ONE thing at a time!!! Variable – The things that change in an experiment TWO TYPES: Independent variable – the thing that you changed Dependent variable – what changed as a result at the end (usually something you can measure)

35. FOR POPCORN? Independent variable? “1” thing “I” changed - the temp of the popcorn Dependent variable? What measure at the end to know results - the amount of kernels that pop

36. * should repeat the experiment over and over to make sure you keep getting the same results before you make a conclusion 5.CONCLUSION - What you found out. Answer the problem in step one in a complete sentence. Talk about the DATA you collected

37. WHAT WERE THE STEPS? 1.State the Problem 2.Gather information 3.Form a Hypothesis 4.Conduct an Experiment 5.Conclusion

38. BACK OF NOTES You have an example going over all of the steps to help you with any assignments. +++++++++++++++++++++++++++++ EXTRA CREDIT – Answer the question Why does popcorn pop?

39. LET’S SEE AN EXAMPLE OF SCIENTIFIC METHOD IN USE VIDEO Assignment 1.2 https://www.youtube.com/watch?v=CxYfJA0M 6N0&feature=youtu.be

40. FINISH YOUR VIDEO QUIZ NOW YOU HAVE 2 MINUTES TO TALK TO OTHER STUDENTS ABOUT YOUR ANSWERS DO NOT JUST CHANGE IT! TALK AND FIGURE OUT WHO IS RIGHT AND WHY

41. TRADE PAPERS AND SIGN YOUR NAME ON THE TOP LEFT OF THE SHEET

43. HOMEWORK GET YOUR SYLLABUS SIGNED CAN DO EC: Why does popcorn pop? Write it down on a piece of paper and the source (what website you got your information from) PUT FOLDERS AWAY, SIT AT SEAT, PUSH IN CHAIR
