1      Research and Brainstorm

                          How do different scientists use glass?  How do scientists
                          invent new types of glass to solve problems?  What is the
                          most important property of glass?  Will the shape of a
                          greenhouse affect the temperature?




                  2      Design and Build

                          Sketch your greenhouse design.  What purpose will
                          each part serve?  What materials will work best?  Build
                          a model.





                  3      Test and Improve
                          Attach a thermometer to the inside of the model and
                          place it under a light source.  Record the starting
                          temperature inside the greenhouse.  Turn the light
                          on and record the temperature every 5 minutes
                          for 20 minutes.  Did it work?  How can you improve
                          it?  Modify your design and try again.





                  4      Reflect and Share
                          Collect data to figure out whether the shape of a
                          greenhouse changes how effective it is.  Which shape is
                          most successful?  How do you know?  Can you think of
                          another way to test your greenhouse model?
