Once correct, the students will paste their parts onto their diagram

Technology used: Notebook through a Tablet
Unfortunately, my classroom is not equipped with a SMARTboard. It is possible to involve the students with my tablet. They would simply have to use the pen to grab and drag the parts of the frog. Limited computers, places the virtual dissection as a guided instruction piece.

BACKGROUND INFORMATION: Purpose:
In this lab, you will dissect an frog in order to observe the external and internal structures of frog anatomy
Frogs are classified as amphibians "live a double life". Frogs are part of the amphibian order, Anura. Tadpoles are aquatic and herbivores. Adult frogs can live on land and in water and are carnivores. Strong muscles and special fused bones help frogs be powerful swimmers and jumpers. Frogs have loose, mucous lined skin to help them escape from predators, and keep them wet which aides in cutaneous respiration (breathing through the skin). Tadpoles breath through gills. Frogs breath though underdeveloped lungs and their skin. Cutaneous respiration limits the frogs body size. The backs of frogs are dark, while their undersides are light, to camouflage them on land and water. Frog brains are smaller and less developed than other vertebrates, they also have a 3 chambered heart. Jul 12­10:57 PM
