Notes: Scientific Inquiry

1
Notes Scientific Inquiry

• Mr. Trace
• 7th Grade Science
• Read pgs 18-26
• Copy underlined portions for notes.

2
How Scientists Think

• Scientists use the same steps that most people
  use everyday to solve problems without even
  knowing it.
• You probably think like a scientist all of the
  time.

Scientific Inquiry

• Scientific Inquiry the ways in which scientists
  investigate the natural world and propose
  explanations based on evidence they gather.
• Scientific Inquiry and the scientific method are
  the same thing.

1. Ask a Question

• Ask a Question Ask a question based on
  observations.
• How can I do well in science?

Video
5
Ask a Question Cont.

• Observations using one or more of your senses to
  gather information.
• You have noticed you are not doing as well in
  science as you would like.

6
Two types of Observations

• Quantitative Observations dealing with an number
  or amount.
• Qualitative Observations that deal with
  descriptions.

7
Ask a Question Cont.

• Inferring when you explain or interpret the
  things you observe.
• I have not been paying too much attention to what
  Mr. Trace has been teaching lately.

8
Ask a Question Cont.

• Predicting make a forecast on what will happen
  in the future based on your observations.
• If I pay attention more and follow directions
  more carefully, I may do better.

9
2. Form a Hypothesis

• Form Hypothesis. A testable explanation for a set
  of observations or answer to a scientific
  question.
• I can listen to the teacher and follow
  instructions carefully.

10
Hypothesis

• A hypothesis can also be written as an IfThen
  statement such as, If I study hard, then I will
  get an A.

11
Hypothesis

• A hypothesis must be testable.
• Researchers must be able to carry out
  investigations and gather evidence that will
  either support or disprove the hypothesis.

12
3. Test the Hypothesis

• Test Hypothesis. Form and conduct an experiment
  to test your hypothesis.
• I will follow directions for one assignment and
  not follow directions for another.

13
Experiments

• Variables the factors that can change in an
  experiment. You should only have one variable
  that changes.
• In our experiment, it should only be listening
  and following directions in different amounts.

Video
14
Control

• A control is a part of the experiment to which
  you can compare the results of the other tests.
• Can be the rest of the class continuing to do the
  same thing.

4. Analyze Results

• Analyze Results. Collect and put data into a
  readable form. Charts, graphs, and tables work
  well.
• What happened when you followed directions? When
  you didnt follow directions?

16
5. Conclusion

• Conclusion A summary of what you have learned
  from your experiment. When I followed directions
  I got an A, when I didnt follow directions I got
  an F. I was right, if I listen and follow
  directions, I will do well in science.

6. Communicate Results

• Communicate Results. Share your results in
  written or presentation form.
• Show and tell your family that you got an A in
  science.

18
Out of Order?

• The steps of the scientific method can be changed
  or rearranged depending on needs.
• If your data does not prove your hypothesis you
  can create a new hypothesis and retest.

19
Experiment Form

• All lab write ups need to have the following
  sections.
• Title
• Problem
• Hypothesis
• Materials
• Procedures
• Data/Analysis
• Conclusion
• Graph

20
Experiment Form

• Title Explains the experiment.
• Doing Well in Science.
• Problem What do you want to learn?
• How can I do well in science?

21
Experiment Form

• Hypothesis What do you think the answer to your
  question may be?
• If I listen and follow directions, I will do
  well.
• Materials A numbered list of everything you will
  use.
• 1. Teacher.
• 2. Grade results.

22
Experiment Form

• Procedures A numbered set of instructions for
  performing your experiment.
• 1. Go to class.
• 2. Listen and follow directions.
• 3. Analyze grade results.

23
Experiment Form

• Data/Analysis Record your data into a chart or
  graph.
• Listened A
• Didnt listen D
• Conclusion What did the results of your
  experiment prove?
• To do well in science, you should listen
  carefully and follow directions.

The Real Test

• Lets launch ourselves into a fun test.
• This one will keep you hanging.
