As a frog grows what changes and transformations it is going through? Compare and contrast different stages of the lifecycle of a frog with a Venn diagram. In this file, you will find four diagrams, each in color and black&white. Your students will compare eggs and a tadpole, a tadpole and a tadpole with legs, a tadpole with legs and a froglet, a froglet and an adult frog. Sample answers are also included.
