2. Collect Data
        Use the following Interactive Activity to collect data on this question yourself, and try this experiment with a few
        friends.
        Use a stopwatch. Have two or more subjects engaged in a conversation, and ask one of them to let you know when
        he or she thinks a minute has passed. Record how much time actually passed. Repeat this several times with the
        same or different subjects.
        Problem 5: Whither Or Not Nuclear Power
        1. Ask a Question

        Should nuclear power be developed as an energy source?
        2. Collect Data
        Twenty-five people completed the following questionnaire:


           Question 1:                                                                           Yes     No
           Are you concerned about future accidents at nuclear reactors?
           Question 2:
           Is the growing amount of radioactive waste from nuclear reactors posing problems for the future?  Yes  No

           Question 3:                                                                           Yes     No
           Do you think we ought to make a more through examination of safe energy supplies?
           Question 4:                                                                           Yes     No
           Should we seek to reduce the number of nuclear power stations?
























        The responses were as follows:
