The dissection of preserved frogs is an engaging introduction to vertebrate anatomy and mature body systems. Exploring the anatomy of the frog allows discussions about adaptations and how anatomical structures are related to their functions. This activity can be performed by a range of students, from elementary school students who are just learning about body systems to college students who are studying comparative anatomy. The dissection is simple, only requiring dissecting scissors, and can be completed in 1 or 2 class periods depending on your preference.

Mammalian kidneys are part of the urinary system, functioning with the ureter, urinary bladder, and tubular urethra. These organs remove unwanted cellular waste, excess salts, and toxins from the blood. The kidneys play a part in regulating water balance and pH levels in the mammalian body. They also help regulate blood pressure and red blood cell production. Dissecting a kidney allows you to trace the path of wastes and urine through the organ and better understand its function.

An earthworm dissection lab provides an economical and convenient opportunity for students to practice their dissection techniques before progressing to more complex specimens such as frogs or pigs. The dissection can be performed in about 30 minutes and requires only scissors, forceps, and dissecting pins. A hand lens may be helpful.
