This medium worksheet gives second graders a deeper look at chicken and frog life cycles. Part A has nine fill-in-the-blanks introducing harder words like incubation, egg tooth, and rooster, plus questions about tadpoles growing back legs first and frogs catching insects with their sticky tongues.
Part B is a matching activity that pairs egg, chick, tadpole, and adult frog with the right description, like breathes with gills and swims or covered in soft down feathers. Mixing vocabulary and matching helps students connect each stage to what the animal actually does.
