The Five Senses
How can we learn about our natural world without using any tools?
We can use our 5 senses to help us make observations about the world around us. The 5 senses are Sight, Hearing, Touch, Taste, and Smell.
Sight: We use this sense to see our surroundings.
Sense Organ: The eyes are the sense organ that helps us see the world. Light reflects off an object and enters the eye to produce an upside-down image. The eye then sends a signal to the brain, which corrects the image for us to see.
Hearing: We use this sense to listen to sounds around us.
Sense Organ: The ears are the sense organ that helps us hear different sounds. Sound waves enter our ears, and those vibrations are converted to signals. These signals are sent to the brain, which changes it to the sound we hear.
Touch: We use this sense to feel our surroundings.
Sense Organ: The skin is the sense organ that helps us touch and feel objects around us. It helps us detect if something is hot or cold, soft or rough, and liquid or solid.
Taste: We use this sense to find various tastes and flavors.
Sense Organ: The tongue is the sense organ that helps us detect different tastes. Taste buds on the tongue help us differentiate if the food is sweet, spicy, sour, or bitter.
Smell: We use this sense to detect different smells around us.
Sense Organ: The nose is the sense organ that helps us to smell. We breathe in the air, containing small particles, through our nostrils. This is then sent as a signal to our brain, which identifies the smell.
All of our 5 senses work together to help us survive in the world. These senses give us the ability to interact with our environment.
