Play/Go On Go Back Home/Menu STUDENTS Teachers/Parents AUDIENCE LEARNING ENVIRONMENT INSTRUCTIONAL ACTIVITIES OBJECTIVES The audience for this Five Senses PowerPoint is for children in 1st grade. The students can do this by themselves after learning about The Five Senses. 1st grade children will do this activity and quiz on computers at home or at school. This activity will be attached to the teacher’s home page on his/her website. Given the quiz at the end of the PowerPoint, students will be able to identify the body part that is associated with the sense and read the fun facts to answer the quiz question with 80% correct accuracy. Orientation – the PowerPoint will test the students about the Five Senses they learned in class Motivation – learning about the five senses by watching Youtube clip Information – fun facts given about each sense Application – diagram and explanation of each body part Evaluation – quiz question given at the end of the information Today, you will be learning about the five different senses. You should already know a little bit about them from class this week! We use our senses everyday! Think about how many times you smell dinner cooking, touch a crayon, hear your friends talking, see your family, or taste yummy treats! Get ready! Here we go! VIDEOS ACTIVITY QUIZ *Click on either the Video Recorder to watch the movie, or the Song Notes to listen to the song! SIGHT HEARING TASTE TOUCH SMELL Eyes are used when you want to look at something, like a dog or your friends. The eye has many parts to help it function. Cornea Pupil Iris Retina Optic Nerve Lens Cornea: outside covering of the iris (or color part of your eye) Pupil: opening of the iris (or colored part) where light shines through Iris: the colored part of your eye Lens: helps your eyes to focus the light being shined in Retina: area in the back of the eye that puts the things you see into secret codes for the brain Optic nerve: the eye’s nerve that sends images from the eye to the brain The pupil changes sizes depending on the amount of light entering the eye. There are 130 million light-sensitive cells in one eye ball! Images are seen upside down to the brain! 1 in 30 people are affected with color blindness. Your nose is used to smell different odors and smells like chocolate chip cookies. The nose has many different tissues inside of it. Nasal Bone Alar Cartilage Columella Cartilage Superficial Depressor Septi Muscle Orbicularis Oris Muscle Lateral Alar Ligament Elastic Tissue Alar cartilage: cartilage (or hard skin like bone) that forms tip of your nose Columella cartilage: the bone that divides your nostrils Nasal bone: rectangular bone that forms part of your nose that is between your eyes Lateral alar ligament: ligaments (or group of tissue) that attach to your forehead Elastic tissue: tissue that supports ligaments (group of tissues) and bones Superficial depressor septi muscle: a muscle that draws your nose downward Orbicularis oris muscle: muscle that connects nose to lips You can tell the difference between 4,000-10,000 smells! As you grow older, your sense of smell gets worse! Odors float upward (not downward!) through the nose! Nose’s pathways gets warmer further back in the canals. The sense of touch is used by the whole body, but is commonly used by the fingers. The finger has many things that help it to feel different touches. Nail Root Nail Matrix Cuticle Nail Plate Distal Edge Of Nail Plate Hyponychium Nail Bed Nail plate: thin growing nail on the upper side of your finger Cuticle: nonliving skin surrounding your nail Hyponychium: the fingertip’s skin under the edge of the nail Nail bed: skin that is under nail Nail root: point where the nail starts to grow Nail matrix: grooves (or tiny scratches) on the nail Distal edge of nail plate: nail tip Some of the sections of skin are more sensitive than others! The body organ used for touching is skin! Our sense of touch shows us the shape, size, and “feel” of our world! The brain analyzes each touch, which signals the body to react. The The ear is the organ used for hearing. ear is made of different structures to perform its hearing task. Outer Ear Ear Drum Ear Canal Middle Ear Eustachian tube Inner Ear Outer ear: the area that collects the different sounds you hear Middle ear: part of the ear where the sound goes to reach the eardrum Inner ear: portion of ear that helps you to hear and balance Ear drum: tiny oval shape thing that separates the middle ear from the outer ear Ear canal: a narrow tube-like passage where sound enters Eustachian tube: tube that connects middle ear to the back of your mouth The ear is an organ for hearing and balance! The outer ear and middle ear mostly collect the different sounds! Sound waves cause the eardrum to vibrate! Fluid inside of your ear keeps the balance, so if it moves you feel dizzy! The tongue is used to create the sense of taste. The tongue is an organ in the mouth, which is one of many structures used for taste. Palatine Tonsil Circumvallate Papillae Lingual Tonsil Foliate Papillae Fungiform Papillae Filiform Papillae Circumvalliate papillae: dome-shape designs on your tongue Fungiform papillae: mushroom shaped bumps on both sides of your tongue Palatine tonsil: tonsils that get big from you being sick Lingual tonsil: tonsil that helps you to speak Foliate papillae: area where many taste buds are at Filiform papillae: “V”shaped, taste bud-less cells on your tongue The tongue has 4 areas of taste receptors that include sweet, sour, salty, and bitter! “Average taster” has 184 taste buds per square centimeter of tongue! Flavors are dissolved in your saliva before any taste bud takes it! The palate in the mouth is also used for tasting! Do you remember how many light-sensitive cells are in the eye? A. 10 B. 130 million C. 160 million D. 3 billion CORRECT! INCORRECT… *HINT: It is less than 150 million, but more than 1 million. As you grow older, your sense of smell gets worse. TRUE FALSE CORRECT! INCORRECT… *HINT: Children have a sharper sense of smell. Which body organ is used for touching? A. Hand B. Finger C. Nail D. Skin CORRECT!
