    Study 
      the instructional material below. Be sure to click on each of the photographs 
      for an enlarged view in a separate window. The 
      larger version is necessary to complete the assignment. 
      It opens in a separate window which can be resized by grabbing the bottom 
      right corner and dragging it. It 
      can also be moved by 
      grabbing the top heading bar and dragging it. 
      Be sure to close the extra window by using the X in IBM, or the close box 
      in MAC when you are finished using them. |

    Print 
      the graph below and use it to record and keep track of the species found 
      in each of the beachrock microhabitats. 
       Be sure 
        to write about what you are learning in the lab section of your notebook. 
        You will be expected to answer questions about the lab activity during 
        the lab self test and lab quiz. It helps to have your text and coloring 
        books open beside you for support.
