Neuron Structure: The Building Blocks of Your Brain
• What is a neuron?
• Why are neurons important?
Today’s Objective:
Explore the parts of a neuron and how they communicate.
Welcome students! Explain that today's lesson focuses on the neurons—our brain’s messengers. Introduce that neurons carry information throughout the brain and body. Set the objective: by the end, students will identify neuron parts and see how signals travel between neurons.
Dendrites: Receiving Messages
• Branch-like extensions on the neuron
• Receive signals (electrical impulses) from other neurons
• Carry messages toward the cell body
Point out the branching structures in the diagram. Explain that dendrites receive incoming messages from other neurons.
Cell Body (Soma): Processing Center
• Central part of the neuron containing the nucleus
• Processes incoming signals from dendrites
• Decides if the signal is strong enough to pass on
Highlight the cell body (soma) in the diagram. Explain it contains the nucleus and integrates signals.
Axon: Sending Messages
• Long, slender fiber extending from the cell body
• Transmits electrical signals away from the soma
• Often wrapped in myelin sheath to speed up transmission
Show the long fiber in the diagram. Explain the axon carries messages away from the cell body.
Synapse: The Communication Gap
• Tiny space between the axon terminal of one neuron and the dendrite of the next
• Signals cross this gap using chemical messengers (neurotransmitters)
• Enables neurons to connect and form networks
Point to the gap at the end of the axon terminals. Emphasize that neurons don’t touch but communicate across a synapse.
Signal Transmission: Step by Step
- Dendrites receive an electrical impulse
- Impulse moves into the cell body (soma)
- Impulse travels down the axon
- Neurotransmitters release at the axon terminal
- Signal crosses the synapse to the next neuron
Walk through each numbered step on the slide, showing how an electrical impulse travels through the neuron and across the synapse.

Activity
Neuron Communication Role-Play Cards
Use these cards to help students act out how a signal travels through a neuron and across the synapse. Cut the cards apart and distribute one card per student (or per small group) during the role-play portion of Session 2.
Dendrite Card
Role: Dendrites receive incoming electrical impulses from other neurons.
Action: Stretch your arms out as if catching a signal. When the teacher says “Signal incoming,” pass the message to the Cell Body student.
Cell Body (Soma) Card
Role: The cell body processes the incoming impulse and decides whether to send it on.
Action: When you receive the signal from the Dendrite, nod your head and say “Processed!” then pass an imaginary impulse down to the Axon student.
Axon Card
Role: The axon carries the electrical signal away from the cell body toward the axon terminal.
Action: When you hear “Impulse received,” wave your arm like a conveyor belt moving the impulse toward the Synapse student.
Synapse Card
Role: The synapse is the gap between neurons where chemical messengers cross.
Action: Stand about an arm’s length from the Neurotransmitter student. Hold your hands apart and say “Ready to receive.”
Neurotransmitter Card
Role: Neurotransmitters are chemical messengers that carry the signal across the synapse.
Action: When the Axon student arrives at the Synapse, step forward, hand over a small object (like a pom-pom or token), and say “Here’s the message!” then move on to the next neuron’s Dendrite.
Teacher Tips:
- Shuffle and pass out cards so students don’t know which role they’ll get.
- Prompt each card holder with cues (e.g., “Signal incoming!” “Impulse received!”).
- After the role-play, debrief: ask students to describe the pathway of a signal from dendrites to the next neuron.
When every group has acted out the process, have volunteers explain each step in their own words.

Slide Deck
Senses & Memory: How We Remember the World
• What are our five senses?
• How do senses help us form memories?
Today’s Objective:
Understand how sensory input leads to memory formation.
Welcome students! Today’s lesson explores how our five senses send information to the brain and how these inputs become memories. Set the objective: by the end, students will describe sensory information flow and the steps of memory formation.
Meet the Five Senses
- Sight – eyes see light & color
- Hearing – ears detect sound
- Smell – nose senses odors
- Taste – tongue tastes flavors
- Touch – skin feels pressure & texture
Ask students to name the five senses and give quick examples (e.g., sight—colors, smell—flowers). Introduce each sense and its basic function.
From Senses to the Brain
- Sensory receptors gather information
- Signals travel via nerves to the brain
- Brain processes and interprets input
- We experience sensations and understanding
Explain that each sense has special receptors that send signals along nerves to the brain. Walk through each step using student examples.
Steps of Memory Formation
• Encoding: Converting sensory input into a memory trace
• Storage: Keeping encoded information in the brain
• Retrieval: Recalling stored memories when needed
Define the three stages of memory formation: encoding, storage, and retrieval. Provide real-life examples (e.g., remembering a friend’s face).
Senses & Memory Mapping
Notice how each sense connects to the brain’s memory center.
Display the Senses Diagram and point out how each sense pathway connects to areas like the hippocampus. Highlight the flow from sense organ to memory hub.
Memory Game Preview
• Grab your Memory Game Cards
• Match each sensory item with its memory step
• Work with a partner to test your learning!
Preview the upcoming memory game. Explain that students will work in pairs to match sensory items with memory stages using the Memory Game Cards.
Reading
Senses Diagram
Below is a simplified illustration showing how information from each of our five senses travels to the brain. Read the pathways and trace them with your finger.
Sight
Eye → Optic Nerve → Occipital Lobe (Visual Cortex)
Hearing
Ear → Auditory Nerve → Temporal Lobe (Auditory Cortex)
Smell
Nose (Olfactory Receptors) → Olfactory Bulb → Olfactory Cortex
Taste
Tongue (Taste Buds) → Cranial Nerves → Gustatory Cortex
Touch
Skin Receptors → Spinal Cord → Parietal Lobe (Somatosensory Cortex)
Notice how each sense organ connects through nerves to specific areas of the brain. These pathways are key to forming memories.

Game
Sensory Memory Matching Game
Use these cards to play a classic memory (concentration) game, matching each concept card (a sense or memory step) with its correct description card.
Materials:
- Print two pages of cards (one with terms/concepts, one with definitions).
- Scissors to cut cards apart.
- Shuffle all cards and lay them face-down in a grid.
How to Play:
- Students take turns flipping over two cards.
- If the two cards match (concept + its definition), the student keeps the pair and takes another turn.
- If they don’t match, flip them back face-down and the next student goes.
- Continue until all pairs are found. The student with the most pairs wins!
Concept Cards (8)
- Sight
- Hearing
- Smell
- Taste
- Touch
- Encoding
- Storage
- Retrieval
Definition Cards (8)
A. Eyes detect light and color (information travels via the optic nerve to the occipital lobe).
B. Ears detect sound (information travels via the auditory nerve to the temporal lobe).
C. Nose senses odors (information travels via the olfactory receptors and bulb to the olfactory cortex).
D. Tongue tastes flavors (information travels via cranial nerves to the gustatory cortex).
E. Skin senses pressure and texture (information travels via the spinal cord to the parietal lobe).
F. Converting sensory input into a memory trace—first step of memory formation.
G. Keeping encoded information in the brain over time—second step of memory formation.
H. Recalling stored information when needed—third step of memory formation.
Tip for printing:
- Print one copy of the “Concept Cards” page and one copy of the “Definition Cards” page per group.
- Cut along the lines to create individual cards.
- For larger classes, have multiple sets ready so small groups can play simultaneously.
When students finish, debrief by asking volunteers to explain one matched pair and why it goes together.
