Studying the life cycle of a frog teaches young students about biological development. The frog's life cycle contains various stages that can be incorporated into a craft activity to make the lesson memorable. Paper towel rolls come in handy as an economical and effective craft material for frog life-cycle projects.
Frog on a Log
In this craft, the frog's life cycle is depicted on a paper towel tube, which is painted to look like a log. One end of the log represents the beginning of the life cycle, while the other end represents the last cycle. Cut bubble wrap to symbolize the frog eggs, which you can glue directly onto the paper towel tube. The tadpoles can be constructed out of brown pipe cleaner shaped like an oval. Glue a small brown pompom on one end as the head and twist the ends of the pipe cleaner together to represent the tadpole's long tail. The full-grown frogs are made out of large green pompoms with googly eyes and green pipe cleaner legs.
Life Cycle Puppets
Use a paper towel tube to make a stand for frog life cycle puppets. For this project you need craft sticks and paper cutouts of frog eggs, tadpoles and frogs. Glue the paper cutouts to the ends of the sticks for the puppets. Lay the paper towel tube horizontally and cut three slits across the tube with a craft knife or scissors. Insert the sticks into the slits so that they are arranged in order of the life cycle. Tape the paper towel tube onto a piece of construction paper so that it stays in place. Allow kids to use the puppets in a dialogue or activity about frog life cycles.
Discuss the developmental stages of the tadpole, which includes going from a tadpole without legs to a tadpole with legs. The tadpole morphs into a tiny frog, or froglet, before becoming full-grown. Cut a paper towel tube into three sections, one for each stage. Have kids paint the first tube brown, the second tube brownish-green and the third tube green. For the first stage of the tadpole, kids glue a large pompom head to one end of the brown tube and pinch the tube shut just past the head and staple it closed. For the brownish-green tube, glue the pompom head on one end and insert four small pieces of green pipe cleaner into the sides of the tube to represent the developing legs. Staple the open end of the tube shut to resemble the tail. On the green tube add a pompom head and longer pipe cleaners for the legs. Fold down the other end and staple it to represent the disappearance of the tail as the tadpole transforms into a froglet.
Kids cut two long paper towel tubes in half lengthwise to make four smaller tubes. Provide kids with permanent markers and tempera paints. Instruct the them to stand the tubes on end and draw a picture of frog eggs on one tube, a tadpole on the second tube, a tadpole with legs on the third and a frog on the fourth tube. Allow the paint to dry overnight. Create a mock pond with an oval sheet of blue construction paper. Have kids paint rocks and lily pads on the "pond." Place the tubes on the pond, standing up vertically, to show the progression of the life cycle.
