Question: • Do people of different ages have a different sense of smell?
Why did I pick this question? • 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.
Hypothesis • 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.
Explanation of my hypothesis • I think that older people will have a harder time because of ageing and younger people are more new.
Interesting facts from research • 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.
Material List • Plastic cups • Blindfold • Strawberry jam • Peanut butter • Onions • Peaches • Dog food • Hershey's chocolate syrup • Pens • Papers
Procedure • 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
Variables • Grandma Joan age 67 • Ashley age 46 • Caley age 17 • Savannah age 10
Observations from experiments • 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
Data • 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.
Analysis • 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
Conclusion • 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?
