There are at least 10,000 species of birds in the world, each species displaying its own unique characteristics. One of those characteristics is the shape of the bird's beak. A wide variety of beak shapes can be found among birds, each one specifically designed to meet the survival needs of the species. In this 6th grade science fair project you will hypothesize what birds eat based on the shape

There are millions of species of plants and animals, and the ability to study them requires a system for classifying them. Taxonomy is the study of how living things are related to each other. By classifying a species, it is possible to find how closely it is related to other species based on its link to a common ancestor. In this science project, you will visit a zoo, botanical garden, or other

Will neutral water tadpoles live longer then acidic or basic ones? My hypothesis stated that, if one tadpole lives in neutral water and another lives in acidic water, the one in neutral will live longer. I feel th
