Senses Concept Map
I. Feel
The
sense of touch can happen all over your body.
Nerve endings in the skin transmit sensations to the brain. The fingertips and the sexual organs have
the greatest concentration of nerve endings.
Cold, heat, contact, and pain are the four kinds of touch
sensations. Hairs magnify the
sensitivity and act as an early warning system for the body.
A. Everywhere
B. Dermis
1. Nerve
Endings
2. Brain
II. Sight
The eye
is like a camera. The eyes take in light
from what you are looking at and make a tiny picture of it on the back of the
eyeball. Nerves in the eye take a
message to the brain of the picture. The
brain tells us what we are looking at.
A. Pupil
B. Retina
1. Lens
2. Optic
Nerve
III. Taste
A. Taste
Buds
Taste
buds are sensory organs that are found on your tongue. They allow you to experience tastes that are
sweet, salty, sour, and bitter. All the
small bumps on your tongue are called papillae, and most of the bumps contain
taste buds. The taste buds have
microscopic hairs called microvilli that send messages to the brain about how
something taste. Most people have 10,000
taste buds and they are replaced every 2 weeks.
An older person may only have about 5,000 taste buds due to taste cells
not replicating.
1. Papilla
2. Microvilli
B. Nose
IV. Smell
The
sense of smell works by vaporized odor molecules floating around in the air
reaching the nostrils and dissolving in the mucus. Underneath the mucus, in the olfactory
epithelium, specialized receptor cells called olfactory receptor neurons detect
the odor. The olfactory receptor neurons
transmit the information to the olfactory bulbs, which are located at the back
of the nose. The olfactory bulbs have
sensory receptors that are part of the brain that send messages directly to the
most primitive brain centers where they influence emotions and memories, and
also to the higher centers where they modify conscious thought. These brain centers perceive odors and
provide memories to remind us about places, people or events associated with
these olfactory sensations.
A. Nostril
B. Neuron
1. Cilia
2. Odor
Molecule
A. Outer
Ear
B. Middle
Ear
1. Hammer
bone
2. Anvil
bone
3. Stirrup
bone
C. Inner
Ear
In
the inner ear the liquid and hairs are in a curled tube called the
cochlea. The liquid and hairs move due
to the bones in the middle ear vibrating when the eardrum does. Messages move along nerves to the brain. Then
the brain tells you what the sound is.
The inner ear also helps us keep our balance. The liquid in the inner
ear swirls about when you move. Nerves in the inner ear tell your brain which
way you are moving, which helps you to keep your balance
took something so common and made it very educational and understanding.. nice!
ReplyDeleteI think that this is a good topic because its general and everyone uses them. You did a really good job of explaining each sense. You seem to really know what your talking about. The map is very organized. The only thing that I would change would be the sight part of the map. It has black links and I can't read it or see it from the back. Overall good job!
ReplyDeleteI love the 5 senses
ReplyDeleteIt is very interesting to a child as well
You were very informational for older people
I don't think children would know as much as you told.
Would be helpful if you just teach them their senses first and then become more informational on down the line
I loved how you did your concept map on the senses. I feel this is a very important topic for students to learn. The pictures do a good job showing what each sense is. This topic can be taught to many different grades depending on how in detail you go.
ReplyDeleteI would choose a different color for hearing its really bright and hard to see but other than it is a good idea!!
ReplyDeleteI like how all your topics/subtopics are different colors. keeps them separated. Some words you can't really see so I would maybe change the colors. Need to make words more understandable for younger kids.
ReplyDeleteI thought Katherine knew a lot about the subject but she used a lot of big words that kids may not know. The map was organized very well though and she did a good job describing it.
ReplyDeleteI like this topic, because this is something that you will get a chance to teach in future. I think that this would be a great topic to teach middle school students! The babydoll example would be a good tool to use! Good job! :)
ReplyDeleteThe hearing and seeing are very hard to see. I would suggest using a different color font or boxes in the concept map. I also think that the background color is a bit dark. I might want to lighten it up a bit for the classroom.
ReplyDeleteGood topic! From experience with younger children a lot of them aren't entirely sure what the 5 senses are..mostly because the 5 senses are seen as "common sense" knowledge and aren't focused on as they should be.
ReplyDeleteThis is a good lesson to teach to kids. The concept map is very visual and you seem to know a lot about what you are talking about. I would say maybe make it more visually appealing to kids by brighter colors.
