Classroom & Home Ideas

Neuron color key. Color the cell body, dendrites, and long nerve extension in three different colors, then make a matching key beside the neuron.
Signal path arrows. Add small arrows along the branching neural pathways to show a signal moving toward the brain.
Brain pair comparison. Color the two brain characters with different palettes, then list one job of the brain under each figure.
Nervous system poster. Color the humanoid nervous system page and mark the brain, spinal cord, and branching nerves with three labels.
Neuron pattern display. Give each student a radial or symmetrical neuron page, then arrange the finished sheets in a circle on the science wall.
Anatomy style sort. Place a cute neuron, an easy brain, a realistic profile, and a detailed network side by side. Ask students to sort them from simplest to most detailed.
