									 Lab #2
Maze Lab
               Problem
• What variables can change the amount of
  time required to complete a maze?
                 Materials
• Printed Maze
                  Procedure
1. Obtain a printed maze. Have your classmate
   time how long it takes to complete the maze.
   Record this time in the control section of chart.
2. Choose a way to change the experiment, write
   this under independent variable.
3. For constants, write all the factors that will stay
   the same.
4. Write a hypothesis on how the independent
   variable will affect the time.
5. Record the time required to complete the maze
   as the dependent variable. (3 times)

                     Treatment
                         Conclusion
1.   Summarize the lab activity and explain if your hypothesis was supported
     or rejected (use your data to justify your response).
2.   What is the scientific method? How was the scientific method used for
     this lab?
3.   What is a control? Explain the importance of a control in this experiment.
4.   Why is it important that scientific experiments be repeated?
5.   What is the difference between a dependent and an independent
     variable?
6.   What is the difference between a theory and a hypothesis?
7.   By completing the maze more than once you introduce another variable.
     What is this variable? This variable likely affected the time required to
     complete the maze. How would you eliminate this variable? Would
     eliminating this variable solve the problem? Explain.
8.   Design an experiment to test the effects of salt water on seed
     germination. What would be your control, independent variable and
     dependent variable? Complete a chart similar to the data chart.
