SENSES
What are the five senses?
SENSE OF TOUCH, SENSE OF SMELL, SENSE OF HEARING, SENSE OF SIGHT, and the SENSE OF TASTE
Sound waves move through vibrations in WHAT?
THE AIR
How many eyes do most humans have?
TWO
Where are touch receptors located?
IN OUR SKIN, ALL OVER OUR BODY
Scents can sometimes trigger THESE, taking us back to a certain time or place.
MEMORIES
(Like when I smell hot asphalt roads, and think about Silver Dollar City.)
Sometimes referred to as a part of the sense of touch, what lets us know where are body parts are in relation to each other and lets us feel the sense of weight and pressure?
PROPRIOCEPTION (pro-pree-oh-sep-tion)
(Remember we tested this when we raised our hands above our head and tried touching our nose with each hand.)
If there is no air (like in a vacuum), we hear WHAT?
NOTHING
What can someone use to take the place of a missing eye?
What part of our body has the most touch receptors?
THE FINGERTIPS
How do scents travel from one place to another (like smelling burning cookies in a room on the other side of the house from the kitchen)?
SMALL PARTICLES FROM THE THING YOU SMELL TRAVEL THROUGH THE AIR
(these small particles are made of chemicals your nose can recognize by certain receptors...the shape of the chemical fits into the receptors that matches it's shape. Like a puzzle!)
This sense is considered the strongest.
THE SENSE OF SIGHT
Vibrations move through the ear canal, through the ear drum, and into this snail shaped spiral?
THE COCHLEA
Illusions are one way that shows us that we can not always WHAT?
WE CAN'T ALWAYS TRUST OUT EYES
What are the different sensations we can feel using our sense of touch? Name at least 3.
WE CAN SENSE PRESSURE, VIBRATION, TEMPERATURE, PAIN, and TEXTURE
When is the sense of smell formed in a human?
BEFORE WE ARE BORN
(It's the first sense to form when we're a baby.)
What sense is often considered the weakest?
THE SENSE OF SMELL
What do the stereo-cilia, or little bundles of hair like filaments, in the cochlea do?
THEY TURN VIBRATIONS INTO ELECTRIC SIGNALS
(It's the electric signals that are sent to the brain!)
When light bounces off something and into our eyes, the image is actually WHAT?
How can a detective use their sense of touch when working a case?
LOTS OF THINGS!
(Some examples could include:
They can tell how hot or cold something is.
If there is a breeze.
If something is wet.
If something is heavy or light.
If something feels gritty, or soft, or sticky, etc.)
What do we get every 28 days?
A NEW NOSE!
(All of our smell receptors are replaced about once a month.)
What sense do we rarely use with forensics?
THE SENSE OF TASTE
How can a detective use their sense of hearing to solve a case?
LOTS OF WAYS!
(Some examples of right answers are:
To detect danger
As a way to collect more information about a person or location.
Listening to interviews of witnesses
Wiretapping
Helping them be aware of where someone is.)
What part of the eye is the color we talk about when we ask people what color their eyes are?
THE IRIS
What is the outer most layer of the skin?
THE EPIDERMIS
The scientific name for the system that makes up our sense of smell is?
THE OLFACTORY SYSTEM
