The document provides instructions for students to create a "nerve necklace" to illustrate the structure and organization of neurons in the brain. Students are instructed to cut out nerve cell boxes from a sheet, fold them, and string them onto a piece of string to form a necklace. When complete, the necklace will show how neurons are arranged with dendrites on one side receiving information and axons on the other side passing messages between cells. The activity is meant to be a formative assessment for students in the 8th grade to demonstrate their understanding of the basic parts and organization of the nervous system.

Assessment Objective: Illustrate important parts and control centers of the brain.
Introduction
The brain, spinal cord, and nerves are made up of billions of individual nerve cells called
neurons. These cells fire electrical nerve impulses fueled by chemicals in the body. Each neuron
has a roundish cell body with a nucleus surrounded by petal-like dendrites that receive
information, and a long stem like axon that passes along the electrical message to the next
neuron through rootlike tendrils called terminal ends
Materials
24-inch piece of string, scissors, tape, red and blue colored pencils, crayons, or markers
Instructions
1. Cut out the 16 nerve cell boxes along the solid black
lines.
2. Fold each box lengthwise along its dotted line.
3. Thread the string through each folded piece and
tape closed, as shown. Be sure the boxes line up
opposite end to opposite end.
4. Tie the ends of the string together for a necklace.
(Note: You can also make belts using more boxes and a longer piece of string.)
