How Do Senses Send Messages?
Slide 2 / 12
1
Spot the Clue
Your eyes, ears, nose, tongue, and skin spot sights, sounds, smells, tastes, and textures.
2
Nerve Wires Zoom
Nerves are like fast telephone wires. They zoom the message straight to your brain in a flash!
3
Brain Decides
Your brain is the boss! It figures out what you are sensing and tells your body what to do next.
TURN & TALK
Tell your partner about a time your brain reacted super fast, like catching a dropped ball or jumping away from a puddle!
Sense 1 • Eyes
Catching Light to See
Slide 3 / 12
How Your Eyes Work
- Light Enters: Light bounces off objects and travels right into your eye.
- The Pupil: The black center gets bigger in dark rooms to let in more light!
- Brain Picture: Your eye sends light clues to the brain so you see the picture.
Fun Eye Facts!
Blinking Cleaners
You blink about 15 times a minute to wipe dirt away and keep eyes wet.
Rainbow Spotters
Special eye helpers let you spot millions of bright, different colors!
TURN & TALK
Why do you think it is hard to tell what color things are in a super dark bedroom at night?
Sense 2 • Ears
Catching Sound Waves
Slide 4 / 12
Outer Ear
The Sound Catcher
Your outside ear is shaped like a cup. It scoops up invisible sound vibrations moving through the air.
Middle Ear
The Drum & Tiny Bones
Sound waves hit your eardrum. It shakes 3 tiny bones—the smallest bones in your whole body!
Inner Ear
The Snail Shell
A tiny curl shaped like a snail shell turns those shakes into nerve signals that tell your brain what you heard!
TURN & TALK
Gently touch your fingers to your throat and hum a song. What do you feel shaking? How does shaking make sound?
Sense 3 • Nose
Sniffing Out Clues
Slide 5 / 12
Floating Scent Bits
When cookies bake or flowers bloom, tiny invisible scent pieces float into the air.
When you take a breath, scent catchers at the top of your nose trap them and identify what it is!
The Memory Shortcut
Smell is connected directly to your brain's memory bank!
That is why smelling crayons, pine trees, or fresh popcorn can make you remember an awesome day instantly.
TURN & TALK
What is your favorite smell in the whole world? What does that smell remind you of?
Sense 4 • Tongue
The 5 Tastes on Your Tongue
Slide 6 / 12
Your tongue has thousands of tiny bumps with taste buds. They can pick up 5 basic tastes:
🍯
Sweet
Like apples, honey, and ripe strawberries
🥨
Salty
Like pretzels, popcorn, and crackers
🍋
Sour
Like juicy lemons and tangy yogurt
🥦
Bitter
Like broccoli greens and dark cocoa
🧀
Savory
Rich taste like warm soup or melted cheese
TURN & TALK
Why does sour or bitter taste make us make a funny face? How does that keep us from eating spoiled food?
Sense Buddies
Nose + Tongue = Flavor Team!
Slide 7 / 12
Cool Discovery
Taste Needs Smell!
Your tongue can only taste the 5 basic tastes. But your nose can smell thousands of things!
When you chew food, scents travel into the back of your nose to create yummy flavors like chocolate or pizza!
Try It At Home
The Stuffy Nose Mystery
If you pinch your nose tight and close your eyes while taking a bite of an apple slice, it is hard to tell it apart from a raw potato!
Most of what you think you "taste" is actually what you smell!
TURN & TALK
Have you ever had a stuffed nose from a cold? How did your favorite dinner taste while you were sick?
Sense 5 • Skin
Our Body's Touch Blanket

Feels a soft puppy, a gentle breeze, or a feather brushing your cheek.
Pressure
Feels a big bear hug, sitting in a chair, or tying your sneakers tight.
Hot & Cold
Warns you if soup is hot or if an ice cube is freezing cold!
Quick Pain
An alarm bell that makes you pull your hand away from a thorn quickly!
TURN & TALK
Why do you think your fingertips feel tiny details much better than your knees or elbows?
Bonus Senses
Your Body's Secret GPS
Slide 9 / 12
Secret Sense 1
Muscle Map
Your muscles and joints tell your brain where your arms and legs are—even in a dark room!
This is how you can clap your hands with your eyes closed!
Secret Sense 2
Inner Ear Balance
Tiny liquid loops deep inside your ears tell your brain if you are standing up straight or tilting sideways.
When you spin in circles, that liquid sloshes around, making you feel dizzy!
TURN & TALK
Close your eyes and touch the tip of your nose with your pointer finger. How did your finger know where your nose was without looking?
Brain Tricks
Can Senses Be Tricked?
Slide 10 / 12
Eye Tricks (Optical Illusions)
Your brain tries to guess what you see very fast!
Sometimes lines or pictures trick your brain into thinking still shapes are moving or spinning.
Tuning Out Clues
When a feeling stays the same, your brain stops paying attention to it!
Think about putting on your socks: you feel them for 10 seconds, and then your brain completely forgets they are there!
TURN & TALK
Why is it helpful that your brain ignores the feel of your shirt and socks once you have been wearing them for a few minutes?
