Nervous System is a free printable Grade 4 science worksheet that builds foundational understanding of how the brain, spinal cord, and nerves work together. Students complete eight multiple-choice questions, one multiple-select question, and one open-ended prompt about the senses and nervous system. The questions ask students to identify the nervous system’s role, explain how the brain communicates with the body, recognize the skull as protection for the brain, identify major nervous system parts, and understand that the brain sends signals to guide the body’s reactions. Visual identification items reinforce recognition of the brain, spinal cord, and nervous system in illustrations. Use this worksheet to check whether students can distinguish nervous system structures and describe their basic communication functions using age-appropriate science vocabulary. The multiple-select item requires students to identify all three main parts—brain, spinal cord, and nerves—while the final open-ended question gives them space to raise questions about the senses and nervous system. It is suitable for independent practice, review, or a short formative assessment, and includes a complete answer key for efficient checking.

This worksheet helps Grade 4 students identify the brain, spinal cord, and nerves as major parts of the nervous system and explain their basic communication roles. Through eight multiple-choice items, one multiple-select item, visual identification questions, and an open-ended prompt, students practice recognizing the skull’s protective role, understanding that nerves give the brain messages, and identifying signals as the brain’s instructions to the body.
Introduce the worksheet by reviewing a simple body diagram and tracing the communication pathway among the brain, spinal cord, and nerves. As students work through the visual and multiple-choice items, ask them to explain why the skull protects the brain and how signals help the body react. Use the final open-ended question to invite questions about the senses and address them in a follow-up discussion.
Students may select legs as one of the main parts of the nervous system instead of selecting all three correct choices—brain, spinal cord, and nerves—in the multiple-select item. They may also confuse the spinal cord with the spine, identify the forehead rather than the skull as the brain’s protection, or reverse the roles of nerves and signals. Review the picture-based items carefully because students must distinguish the brain from the spinal cord and the broader nervous system.
You can assign this Grade 4 Nervous System worksheet as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key for the multiple-choice and multiple-select items, while the open-ended response can be reviewed for students’ questions about the senses and nervous system. For printable submissions, scan student work with the Wayground for Teachers app to grade it efficiently.
In the worksheet’s Advanced Settings, adjust font spacing or increase the font size to make the visual identification questions and answer choices easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when appropriate for your learners.
