Lab Conclusions

Today we finished writing our conclusions in class.  Some students have been absent or felt rushed to keep up they asked that I put what we did on the blog.  The portions written in blue color may need to be modified based on the student's lab results.

Conclusion

         The distance the rubber band is stretched affects the distance it flies when it is launched.  When we stretched the rubber band 9cm, it went an average of _____ cm.  As we stretched the rubber band further, the average increased until we got to a ______cm average at a 13 cm stretch.  Therefore, stretching the rubber band further makes it launch further.

        The data did support my prediction because I thought the rubber band would fly further the more it was stretched. (Some students may need to change this statement based on the prediction they made, however this should apply to most students).  Some of my data was inconsistent because...student discusses unusually high or low numbers s/he got for example (a rubber band at ______cm stretch rolled to (a very large number)cm and caused the average to be off.)

        I wonder if ...student writes questions that came up during the experiment. For example, "I wonder if our results would change if we used a thicker rubber band."
