Imagine you’re at a cozy cabin in the woods by a sparkling lake. As you explore, the warm sun peeks through the trees and gently touches your face. You see birds flying and chipmunks scurrying around. Someone nearby is cooking, and you can smell the delicious food and the smoky campfire. By the lake, kids are playing and splashing in the water.
Think about all the body parts you use to enjoy these experiences: your ears to hear, your eyes to see, your nose to smell, your hands to touch, and your mouth to taste. These are called our five senses, and they help us understand the world around us.
Our eyes are like cameras. They have special lenses that help us see by taking in light. The light enters through the pupils and focuses on the retina at the back of the eye. Did you know that our pupils get bigger in the dark and smaller in bright light? This helps us see better in different lighting. Some people need glasses to see clearly, and some people see colors differently. But no matter what, our eyes do an important job!
Our ears help us hear sounds. The outer ear catches sound waves and sends them to the eardrum. Inside the ear, tiny hairs vibrate and send signals to the brain to understand the sounds. It’s important to protect our ears from loud noises to keep our hearing healthy.
Our nose helps us smell things. Scents in the air reach olfactory cells in the nose, which send messages to the brain. Smells can make us feel hungry, warn us of danger, or remind us of memories. Our sense of smell is closely linked to our sense of taste.
Our mouth is full of taste buds that help us taste food. These taste buds can sense four main flavors: salty, sweet, sour, and bitter. They also help us feel if food is hot, cold, creamy, or crunchy. Without taste, eating would be pretty boring!
Our skin helps us feel things through touch. Nerves in the skin send information to the brain about what we are touching. Some parts of our body, like our lips, are more sensitive than others, like our elbows. Through touch, we can feel if something is smooth, rough, hot, or cold.
Animals also have senses, and some are even stronger than ours. For example, some animals can see better at night, while others have a great sense of smell or hearing. Dogs can hear sounds that humans can’t, and guinea pigs have a strong sense of taste.
The five senses help people and animals explore, learn, and enjoy the world around them. They work together to keep us safe and make life exciting!

Sensory Scavenger Hunt: Go on a sensory scavenger hunt in your backyard or a nearby park. Use your senses to find different items. Can you find something that feels rough, something that smells sweet, something that makes a sound, something colorful, and something you can taste (with an adult’s help)? Draw or write about what you find and share it with your class.
Sound Detective: Close your eyes and listen carefully to the sounds around you for one minute. What do you hear? Is it loud or soft? Near or far? Try this at different times of the day and in different places. Make a list of the sounds you hear and discuss with your classmates how your ears help you understand your environment.
Flavor Experiment: With the help of an adult, try tasting small samples of foods with different flavors: salty, sweet, sour, and bitter. Use a blindfold to make it more fun! Can you guess the flavor without seeing the food? Talk about how your sense of taste and smell work together to help you enjoy your food.

This video is about the five senses. Imagine you’re at a cabin in the woods next to a lake. You’re exploring as you walk around. The heat from the sun comes through the trees and touches your face. You can see birds flying around and chipmunks scurrying across the ground. Someone nearby is cooking, and you can smell the food and the smoke from their campfire. When you get to the lake, you notice kids playing in the water.
Take a minute to think about the different body parts you use to experience all the things around you: your ears to hear, your eyes to see, your nose to smell, your hands to touch, and your mouth to taste.
As you imagine that cabin scene in your mind, could you hear the birds chirping? Could you see the kids splashing in the lake? Could you imagine smelling or tasting the food that was being cooked? Could you hear the crunch of the leaves under your shoes as you walked or feel the warmth of the sun shining on your face?
Sight, hearing, smell, taste, and touch are called our five senses. They help you gain a clear picture of all that is happening around you. Think of all the wonderful things you’re able to do because of those five senses working together.
Let’s take a look at each of these senses individually.
First, we’ll start with sight. Inside your eye, there are special lenses that take in light to help you see things. Think of your eyes like a camera. The light reflected from different objects enters your eye through your pupils, the front of your eye, and then focuses those images onto your retina, or the back of your eye. Your eyes have some incredible abilities. Did you know that our pupils grow bigger in the dark and smaller when it’s bright? That’s because they are adjusting to the differences in light.
Have you ever noticed when a light is first turned off that you can’t see anything around you, but then after a minute, things become clearer? The saying goes that if you step out into the bright sun, your eyes may squint momentarily until they adjust to the brightness. Not everyone sees things the same way. Some people see very clearly, while others may need glasses or contacts to help them see better. Some people can see color, while others are colorblind, which means they have a hard time telling the difference between various colors. Whether you see clearly or not, your eyes have a pretty important job.
The second sense is hearing. Hearing depends on our ears. There are two parts to the ear: the outer ear and the inner ear. The outer ear, or the part that we can see, catches sound waves and directs them to the eardrum. The inner ear is lined with thousands of tiny hairs that vibrate and send signals to your brain to make sense of what you are hearing. As we get older or are exposed to a lot of loud noises, these tiny hairs can become damaged and cause us to lose some of our hearing, so it’s important that we protect our ears.
The third sense is smell, which comes from our nose. Scents in the air stimulate olfactory cells located in the nose. Those cells send information to the brain, which then identifies what the nose is smelling. Certain smells can make us feel sick, while others can warn us of danger, like if there was a fire. We can suddenly feel hungry when we smell something delicious cooking. Some smells can even trigger memories. Our sense of smell is linked to our sense of taste. If you’ve ever had a cold, you might notice you can’t smell as well, and you also have a difficult time tasting what you eat. Your nose and mouth are connected and work closely together, which brings us to our fourth sense: taste, which happens in your mouth.
Our mouths are filled with thousands of taste buds, which are replaced about every two weeks. Taste buds have very sensitive microscopic hairs on them that send messages to the brain about how something tastes. This helps us experience four main flavors: salty, sweet, sour, and bitter. Many foods you eat may be a combination of these four main flavors. The tongue can also feel whether something in your mouth is hot, cold, creamy, crunchy, or dry. Without our sense of taste, food would be pretty boring.
The fifth sense is feeling or touch. This sense comes from our skin and can be felt throughout the entire body. There are many nerves located in your skin that collect information to send to the brain about what we are feeling. Some parts of your body are more sensitive to touch than others. For example, the skin on your elbow has less feeling than the skin on your lips, which are very sensitive. Most of our feeling is done by our hands. Through touch, we can feel if something is smooth or rough, soft or hard. We may feel something that causes us pain, like a hot stove, or something that feels good, like cool water on a hot day.
Humans are not the only ones who experience the five senses; animals also have senses. Some of the senses are more prevalent or stronger in various animals. For example, some animals can see better at night than during the day. Their sense of night vision helps them locate and catch prey. They can even see camouflaged prey from up to two miles away. Moles have poor eyesight, so they use their sense of smell to help them locate food. Spiders usually have eight eyes, but even with that many eyes, they don’t see well. Instead, they rely more on touch and vibrations to catch their prey. Dogs have excellent hearing and can hear sounds that are not loud enough for human ears. That’s why they can hear a dog whistle, but we can’t. Guinea pigs have an advanced sense of taste that helps them identify different food flavors. They have many more taste buds than humans do and tend to prefer foods that taste sweet.
In summary, the five senses work together to help people and animals live, protect themselves, learn, and enjoy the world around them.
