Middle school is the perfect setting for teaching life science. Observing and studying living organisms are critical to a good, strong program. Preserved specimens, computer simulations, photographs, and videos may be excellent supplements, but they should be used as enhancements to—rather than substitutes for—direct observation and work with living organisms. Maintaining living organisms in a safe and educationally sound manner requires serious effort. Discover in this chapter why expending the time and energy on a "lively" science classroom is well worth the endeavor.
