The Scientific Methoda way of problem solving

• The goal of science is to understand the world
  around us

2
Basic Lab Format

• Title
• Problem
• Hypothesis
• Experiment
• Observations
• Conclusion

3
1. Problem

• Clearly states the problem or question you are
  seeking to answer

4
2. Hypothesis/Prediction

• Solution to the problem (educated guess)
• Written (If, Then, Because)
• If-Manipulated Variable
• Then-Responding Variable
• Because-Prediction/Reason
• Based on prior knowledge

5
3. Experiment

• The experiment tests the hypothesis to see if it
  can be supported or not
• 3 parts Materials, Procedure and Variables

6
Parts of the Experiment

• Material List- Must contain all materials
  referred to in Procedure

7

• Procedure Logical steps so others can follow and
  repeat.
• Controlled Variable kept the same in each trial
• Manipulated Variable the one thing you change
• Responding Variable What you are measuring
• Must Have Repeated Trials (3X)

8
Repeated Trials

• Repeat experiment to check accuracy
• To be accepted a science experiment must be
  repeated by another group!

9
4. Results

• Recorded observations and data
• Measurements
• Data table VerticalManipulated variable,
  Horizontal Responding Variable)
• Graph X axisManipulated Data, Y axis
  Responding Data

10
5. Stating a Conclusion

• Must correctly answer the Problem Question (was
  hypothesis supported or not, why?)
• Use data to support Use average data, and
  high/low data
• Conclusive Statement Use data to support and
  write a conclusive statement
