Do people of different ages have a different sense
of smell?
I picked this question because has people get
older they loose their hearing and their eyesight
so I was wondering if they also lost their sense of
smell.
I think older people will have a harder time
trying to see what they are smelling because you
loose more senses has you get older.
I think that older people will have a harder time
because of ageing and younger people are more
new.
The ability to smell and taste breaks down with age.
3 year olds have essentially the same likes and
dislikes as adults in smell.
Women can tell the difference in smell better than
men
Women are significantly more likely than men to
suffer from cacosmia ( feeling ill from the smell of
common environmental chemicals such as paint and
perfume.)
The little hairs in your nose are called cilia.
To know what you are smelling there is a thing called
the olfactory bulb there the smells are recognized
because each smell molecule fits into a nerve cell like
a lock and key.
Plastic cups
Blindfold
Strawberry jam
Peanut butter
Onions
Peaches
Dog food
Hershey's chocolate syrup
Pens
Papers
Put one of each food in four cups
Blindfold person
Have blindfolded person smell the food and guess
what the food is.
Record answers
Repeat steps 1-4 until all foods are used
Share if they have the right answers
Repeat all steps until all variables have smelled
each food
Record data
Find conclusion
Grandma Joan age 67
Ashley age 46
Caley age 17
Savannah age 10
People all got most/all the answers right.
The easiest thing to guess was Peanut butter
The hardest thing to guess what the strawberry
jam
Grandma: Guessed all correct except strawberry
jam she guessed grape jelly
Ashley: Guessed all of them correctly
Caley: Guessed all of them correctly
Savannah: Guessed all of them correctly except
onions she didn’t know.
My analysis was that it did test my hypothesis
because I thought I was right but I was not
because my oldest variable got most of them right
My hypothesis are wrong because my
grandmother got all of them right except one and
she was very close. My questions now are: How
come other senses go bad but sense of smell stays
the same?
