This end-of-topic test for 4th grade science has 29 questions over eight pages and covers NGSS 4-LS1-1 and 4-LS1-2. Five sections move from multiple choice and matching to a fox and mouse diagram, an internal or external sort, and two written responses. The answer key includes model paragraphs on a polar bear in the Arctic and on an animal using its senses to escape danger.
4-LS1-1
“Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.”
Questions 1 to 5, 9 to 16, 24 to 27, and the argument in question 28.
4-LS1-2
“Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.”
Questions 6 to 8 on sense receptors and the brain, 17 and 18 on the brain and eyes, the fox diagram in questions 19 to 23, and question 29.
Ten questions cover plant roots, porcupine quills, the heart, flower petals, and a rabbit that hears a loud noise.
Students match eight functions to a word bank of thorns, lungs, skin, gills, stems, brain, eyes, and roots.
Five questions follow a diagram of a fox and a mouse, from the sense receptor to the brain's response and how the system helps the fox survive.
Students label a shark's teeth, a human's stomach, a bird's feathers, and a dog's heart as internal or external.
Question 28 asks for an argument about one organism, with a claim and at least one internal and one external structure. Question 29 asks students to trace how an animal uses its senses to avoid danger.
Two sittings
Give the test over two sessions. Sections 1 to 4 fit one sitting, and the two written responses in Section 5 fit another.
Day-before review
Use Section 3 on its own as review. Talking through the fox and mouse path prepares students for question 29.
After grading
Share the model polar bear paragraph once the tests are back. It shows a clear claim with one internal and one external structure.
