Lab Analysis

Picture
The scientific method is more than a set of steps that you memorize during science class. It is the way that all scientist do research and solve problems.  It is very important in a chemistry lab because we cannot see the atoms that we are working with. In this section you will also be learning how to analyze your results using two differentequations; % yield and % error.

Important Vocabulary

  1. hypothesis
  2. observation
  3. qualitative data
  4. quantitative data
  5. control
  6. constant
  7. manipulated (Independent) variable
  8. responding (dependent) variable
  9. accuracy
  10. precision

Scientific Inquiry Overview

  • Observations (both direct and indirect) or Background Research to learn about your topic
  • Question-What are you going to research?
  • Hypothesis (if/then statement with 2 supporting statements)
  • Procedure/Experiment (getting data)
  •       Independent Variable-What are you testing?
  •       Dependent Variable-What variable changes due to the independent variable?
  •       Control-Used to compare your results to and is the "norm".
  •       Constants-Factors that are involved in the experiment that need to be kept the same.
  • Analyzing Data
  •       Graphing (3 types of graphs-line, bar, pie)
  •       x-axis = independent variables and y-axis = dependent variables
  • Conclusion-What is the answer to your question? Does it lead to another question?
  •       Graph Interpretation
  •       What would you do differently?
