Note-taking Strategies:

1
Note-taking Strategies

• Watch for main topic, key points, and
  organization of ideas
• Clues from teacher first, second, etc
• Make concise notes that highlight main ideas
• AFTER CLASS
• Clarify notes fill in missing info and
  highlight
• Recite and review once a week
• Before assessment recite understanding main
  ideas

2
The Scientific Method

• logical and organized way to solve a problem

3
Step 1 PURPOSE

• What is the problem?
• - Usually in the form of a question
• - Based on observations of the world!!!

Example Does Miracle Grow makes plants grow
faster than water alone?
4
Step 1.5 Research/Background Info

• search, collect, study information BASED ON YOUR
  PROBLEM
• use a variety of sources
• Always cite your source in a final draft

5
Step 2 Hypothesis

• Testable statement
• Possible explanation for observations
• observe a problem using senses
• Make a prediction
• Ifthen

Example Miracle grow mixed with water will make
plants grow faster than using water alone.
6
Step 3 Experiment

• Test your hypothesis
• Controlled environment
• Independent, Dependent, Control, Constants
• - REPEAT experiment!!!!

Example Grow three plants using only water.
This is the control group. It is used for
comparison. Grow three plants using Miracle
Grow. This is the experimental group. It is
exposed to the variable.
7
IMPORTANT!!!!!

• Experiments should only have 1 variable
• Everything else except for this variable should
  be the same, or constant
• ______________________________
• What is the variable in our experiment?
• What are the constants in our experiment?

8
Step 4 Collect Data

• Keep a record of what happened
• Design table/chart for recording

  HEIGHT (cm)   HEIGHT (cm)   HEIGHT (cm)   HEIGHT (cm)   HEIGHT (cm)   HEIGHT (cm)  
  CONTROL CONTROL CONTROL EXPERIMENTAL EXPERIMENTAL EXPERIMENTAL
 DATE 1 2 3 1 2 3
             
             
             
             
Example Record the height of each plant each
day.
9
Step 5 Analyze Data

• Organize (results) collected data
• Graphs/Tables
• Make comparisons

Example Graph the height of each plant, and
compare the Miracle Grow to the control group
10
Step 6 Draw Conclusion

• Interpretation/summary of results
• Make inferences based on data
• What does the data tell you?
• Is the hypothesis correct or incorrect?

Example The plants that were given Miracle Grow
grew taller more quickly than the plants that
were only given water. Therefore, the
hypothesis was correct.
11
Theory/Scientific Law

• Theory
• Hypothesis well supported and well tested
  broad range of observations over a period of time
• i.e. Plate Tectonics, Evolution, etc.
• Scientific Law
• simple, true, universal, and absolute
• cornerstone of scientific discovery
• i.e. Gravity, Newtons Laws, Thermodynamics, etc.
• THEREFORE methods/results must allow for
  replication!!!
• Science is characterized by both
• continuity and change
