Read a story to the children such as "Friend Frog," by Alma Flor Ada, or "Tale of a Tadpole," by Karen Wallace. Explain that frogs are amphibians and that amphibians thrive in the water and in the children's backyards. Talk about the frog's life cycle.
Print copies of a coloring page illustrating the frog life cycle (see Resources). Give the children paper plates, blue tempera paint, crayons, paint brushes, glue and safety scissors. Ask the children to paint the paper plates. Let the children color the coloring page and cut out the pictures. Show the children how to glue the pictures on the paper plates.
Cut out 10 pictures of frogs (see Resources). Explain to the children that a frog can leap 10 times its body's length. Let the children place the frogs on the floor in a line to illustrate how far a frog can jump. Let each child jump as far as he can and compare the length of his jump to a frog's. Modify the activity by cutting out large "lily pads" from green poster board. Place the lily pads on the floor and let the children jump like frogs from one lily pad to another.
Let the children roll pieces of clay into small balls that resemble frog eggs. Tell the children to pretend to be frog eggs by curling up into a ball. Tap a child on the shoulder. Explain that each child pretends to "hatch" into a tadpole when tapped on the shoulder. The newly hatched tadpole taps another child on the shoulder, signaling that the egg is ready to hatch. Continue the activity until all the tadpoles hatch.
