               Frogs and Tadpoles
        Frogs and tadpoles are alike because they both go in the water.  They both eat food.  They both move around.
        Frogs and tadpoles are different because a frog can hop but a tadpole just swims.  A tadpole has gills to breathe.  A frog has lungs to breathe. 
        I think that watching  tadpoles turn into frogs is cool.
