Grade 4 Science · Plant and Animal Structures
Build Grade 4 Science skills with five 10-question practice tests on plant parts, animal body structures, functions, adaptations, pollination, seeds, life cycles, and investigations.
These Grade 4 Science practice tests help students connect structures to functions in plants and animals. Students study roots, stems, leaves, flowers, seeds, teeth, beaks, wings, gills, fur, shells, adaptations, pollination, life cycles, and evidence from investigations.
For each question, name the structure and ask what job it performs. Then consider how that job helps the plant or animal grow, survive, reproduce, move, get food, or respond to its environment.
