38. THE CUBES! FIRST RULE: Do not touch the cubes!
Let’s brainstorm: What questions do you have about the cubes?

39. What is on the bottom of the cube?
What is evidence? What does the word mean?
Using data (observations), try to convince me and your classmates what is on the bottom of the cube. Provide evidence!

40. Pick up the cubes… Go ahead!
There is no way of knowing the absolute answer to a scientific question.
WHAT? MS B? ALL THAT FOR NOTHING….
Nature of Science

41. Scientific Investigations
Let’s list the steps we went through in our scientific investigation

42. The Scientific Method Identify the problem- make an observation
Research and form a hypothesis
Test your hypothesis- experimentation
Collect and record DATA
Conclusion- Analyze your data. Was your hypothesis correct?

43. 1. Identify the problem/make an observation…
Scientific inquiry begins with observation.
Science inquiry involves asking questions and processing information from a variety of reliable sources.

44. What is an observation?
Lets make some observations about what Miss B is holding…

45. Observations vs. Inferences
Observation- direct way of gathering information in an organized way.
Inference- taking observations and making a logical conclusion

46. Lets make some observations!
I need someone to write on the board for me!

47. Do Now!
Look at the picture below. Make 3 observations and 3 inferences from the picture.

48. Objectives Determine how to write a testable hypothesis.
Identify the 4 components of an experiment.
Compare and contrast quantitative vs. qualitative data.

49. 2. Form a Hypothesis
Hypothesis - a testable explanation of a situation.
Hypothesis that are supported through experiments and data are then accepted in the scientific community.

50. How to write a hypothesis
Hypothesis are written as an “if…then” statement.
Example:
If salt is added to water that is being heated then the water will boil at a faster rate.

51. Identify the hypothesis
A study is being done on the increase in cases of skin cancer. It has been said that skin cancer shows a direct correlation with exposure to UV light. If skin cancer is related to ultraviolet light, then people with a high exposure to UV light will have a higher frequency of skin cancer.
Is this hypothesis a testable hypothesis?

52. Which hypothesis are testable?
Chocolate may cause pimples.
Good instructional design and proper application of media can lead to effective learning.
Bacterial growth may be affected by temperature.
Students who give teachers gifts tend to earn higher grades.
Temperature may cause leaves to change color.

53. Do Now
Write an example of a testable hypothesis if you could do ANY experiment that you wanted. (appropriate of course)

54. After forming a hypothesis you EXPERIMENT!!
You have noticed that the plants in your garden are beginning to wilt and die. This could be due to a number of different things. You want to figure out why this is happening because you yard is starting to look TERRIBLE! First you observe that the plants closest to the house were the first to start wilting. You then observe that there is a gutter dumping water directly into your garden. You hypothesize that this may be the reason your plants are dying. How could you test this hypothesis?
Can you be positive that it is the runoff that is causing the problem?

55. Experiments What is involved in an experiment?
Independent Variable: variable being tested
Dependent Variable: variable being measured
Control Group: group that remains the same
Experimental Group: Group that is manipulated or changed.
Constants: factors that remain the same throughout the entire experiment.

56. Identify the components of the experiment
A group of college students were given a short course in speed-reading. The instructor was curious if a monetary incentive would influence performance on a reading test taken at the end of the course.  Half the students were offered $5 for obtaining a certain level of performance on the test, the other half were not offered money. 
Independent Variable:
Dependent Variable:
Experimental Group:
Control Group:
Constants:

57. Partner Work

58. Collect and gather data
Data- information gained from observations.
Quantitative Data- measurements of time, temperature, length, or other factors.
Qualitative Data- descriptions of what our senses detect.

59. Gather both qualitative and quantitative data about the picture below.

60. What are some ways to present data?
Organize data into a chart
Take data from chart and create a graph
Bar graph
Line graph
Pie chart

61. Analyze Data to from a Conclusion
We have to do something with our data!
What can we conclude from this graph?

62. Report your conclusion!
After experimenting you must come to some type of conclusion either disproving or proving your hypothesis!
Conclusions are published so others can review the results and discuss the merit of the experiment.

63. Do Now Per. 5
1. You may take out your “alive or not” lab to review for your quiz quietly until I instruct you to put them away.
2. WHEN YOU ARE FINISHED WITH YOUR QUIZ…place your quiz in the basket on my desk and take a lab. Begin reading through the lab quietly and answer the following questions in your Do Now section.
List 3 common behaviors of a beta fish.
Why might you see a pile of bubbles on the surface in a betta tank?
Explain what a betta does when it is demonstrating aggressive behavior.
