17. There are patterns in nature.
Patterns are characteristics or interactions between things that repeat over and over.

18. Activity Which branch of science is this? Is there a pattern?
What questions would you ask if you were a scientist studying this?

19. Activity
With your partner, you will now do the same thing with the picture that is given to you.
Which branch of science is this?
Is there a pattern?
What questions would you ask if you were a scientist studying this?

20. Observation vs. Inference

21. CFU What are our five senses?
Why do you think our five senses are so important in science?

22. Standard & Objective
Standard 7c. Communicate the logical connection among hypotheses, science concepts, tests conducted, data collected, and conclusions drawn from the scientific evidence.
Objective: Students will differentiate between Observation and Inference.

23. Observation
Brainstorm the word OBSERVATION

24. What is observation?
An act of watching* something and taking note of what happens.
Observation is used with all five human senses.
You make observations so that you can ask questions.

25. Observation Activity

26. Observation Activity Are there cars parked on the sides of the road?
What color is the pickup truck driving in the road?
Any minivans around?
What does the blue sign say?
What's the speed limit?
Are there any pedestrians on the road?

27. Video Clip How are the Ghost Busters trying to locate the ghosts?
What kind of observations words do they use? Ex. “Look.”
What can you learn through observation?

29. What is an inference?
A logical conclusion based on the information that is available to you.

30. Inference Activity

31. Inference Activity What are you looking at in this picture?
What is going on?
Why do you think this happened?

32. Inference Activity
“It’s hard to live in a studio apartment in San Jose with a man who’s learning how to play the violin.” That’s what she told the police when she handed them the empty revolver.

33. Inference Activity What do you think has happened? Why did it happen?
What are the possible relationships between the violin player and the woman?
How does the story end?

34. Make a t-chart in your notebook.
Demonstration
Make a t-chart in your notebook.
Observation
Inference

35. The Scientific Method
What is the purpose of a flashlight?

36. Scientific Method
What questions can you now ask?
Students brainstorm

37. Scientific Method
Why doesn’t the flashlight work?

38. Scientific method
Answering why the flashlight doesn’t work is the same as making a HYPOTHESIS!!!

39. Scientific Method Make a prediction. Design an experiment.
Conduct an Experiment.
Conclusion.

40. The Scientific Method
Problem: State exactly what problem the investigation is attempting to solve. (Why isn’t the flashlight working?)
Hypothesis: Describe what you thought would happen and why? (The flashlight did not work because_____________).
Experiment: Step by Step instructions on how you will design and conduct an experiment.
Conclusion: What can you draw from this experiment? Are there any errors?

41. Color Changing Milk
Question: What would happen if I mix liquid soap with milk and food coloring?
Hypothesis?

42. Color Changing Milk Experiment/Procedure: Conclusion
1. Pour milk into bowl to cover the bottom.
2. Add one drop of the four colors (yellow, red, blue, and green).
Put dish washing soap on the tip of the Q-tip.
Put the Q-tip in the middle of the milk bowl and hold for 15 seconds.
Repeat this step and put the Q-tip anywhere in the bowl.
Conclusion

43. Color Changing Milk Conclusion
What happens when you add soap to the milk?
Was your hypothesis correct?
Why do you think the food color moves even when the Q-tip is removed?

44. Color Changing Milk Explanation:
Milk is made of water, vitamins, minerals, proteins, and fat.
Adding soap weakens the chemical bonds that hold the proteins together.
So all the fat molecules bend, roll, and twist and bump into each other.

45. Thursday Lab on Scientific Method!!!
For homework, you need to bring a bag of M&M’s!!!

46. M&M Lab Copy down the following so you can turn in: Question:
Hypothesis:
Data:
Total number of M&M’s in bag:
Number of each color in bag:
Green
Brown
Yellow
Orange
Blue…

47. M&M Lab Find a partner. Get 1 bag of M&M’s per group.
Decide on 1 question you would like to answer about your M&M’s. Write it down. DO NOT OPEN THE BAG YET.
Guess the answer (hypothesis). Write it down. DO NOT OPEN THE BAG YET.
Open the bag and answer your question (Data collection/experimentation).
Count the number of each M&M’s in your bag and the colors.

48. Class Data Combine class data.
Is the number of M&M’s constant in each bag?
Are the colors constant?
Multiple trials
Getting an average of the colors will give us an accurate description of the number of M&M’s in a bag.
What would happen if I opened another bag of M&M?

49. Bar Graph X-Y Data table Headings X-Y axes, and labeled
Using your graph, Which group had the highest?
If we opened a new bag, how many do you think we will have?

50. How to use the scientific method?
Do people like to do homework?
Question: Do people want to wear a uniform at school?
Hypothesis: No, they want to wear regular clothes.
Prediction: I will ask 50 people on campus to see if they want to wear uniforms and they will say no.
Conduct experiment: I surveyed 50 people and got their answer.
Conclusion: All 50 people said they would never want to wear uniforms to school because….
