Create a visual representation of an amphibian's life cycle. Using blue bulletin-board paper, attach a large pond shape to the display board. With green and brown paper, create small areas of reeds and cattails near the water's perimeter. Using a frog as an example, illustrate its metamorphosis from left to right across the pond. Place an egg cluster near the left edge of the pond. Next, show the progression to tadpole, froglet and finally, frog.
Use a world map to show where different amphibians can be found. Post brightly-colored photographs of amphibians around the map's perimeter and use string and push-pins to connect each amphibian to its home country or region. Use the amphibians to spark short studies about the countries in which they are found. Have students read about the countries where different and unusual amphibians are found and write captions for the photographs that highlight interesting regional facts.
Use a bulletin board to showcase student artwork. Using drawing instruments or paint, have students create pictures of either brightly-colored amphibians, such as the red salamander, or camouflaged amphibians, such as the horned frog. Use students' artwork to teach about the importance of coloring among amphibians. Encourage students to discuss why some amphibians might have brightly-colored skin while others have drab coloring that blends in with their surroundings. Post short explanations about coloration next to the artwork.
Display writing assignments on a classroom bulletin board. Ask students to choose an amphibian to research. For younger students, have them write a paragraph telling where it lives, what it looks like, what it eats and one interesting fact. Older students can include additional information such as the stages in its life cycle, its defense mechanisms and its place in the food web. Mount each writing assignment on a piece of construction paper to make the assignment stand out on the bulletin board.
