   The microscope has 
   become one of the most 
   recognizable symbols of 
   science.
   Starting with use of a simple lens in ancient 
   times, to the first compound microscope 
   around 1590, and up to the microscopes you 
   are using in 7th grade life science, the 
   microscope has allowed scientists to make 
   discoveries about the “invisible world.”

     What is the purpose of a 
        microscope?
   • To magnify or enlarge the image of tiny 
    objects.
   • The microscopes we will use this year in 
    science can magnify objects 40 times, 100 
    times, and 400 times the size of the object.
   What type of microscope will we 
    be using in class this year?
   • In 7th grade science, we use a compound 
    light microscope for most of our lab 
    activities.
   • A light microscope uses light as a source 
    of energy for viewing objects.
   • A compound microscope contains two 
    lenses for magnifying a specimen at the 
    same time, the eyepiece (ocular) and one of 
    the objective lenses.
