Raisin: A Dehydrated Powerhouse (Grade 12 Level)
Raisin: A Dehydrated Powerhouse (Grade 12 Level)
The humble raisin, a seemingly simple dried fruit, offers a surprisingly rich tapestry of scientific intrigue. Beyond its delightful sweetness lies a concentrated source of nutrients and a fascinating interplay of biological and chemical processes.
Nutritional Powerhouse:
- Carbohydrate Concentration: Raisins undergo dehydration, a process that removes water and concentrates the fruit's natural sugars (fructose and glucose) by approximately 3-4 times [1]. This results in a high carbohydrate content (around 60-65% by dry weight) [1], translating to a readily available source of energy. The glycemic index (GI) of raisins falls within the moderate range (around 60) [2], indicating a sustained energy release compared to processed sugary snacks that induce rapid blood sugar spikes.
- Dietary Fiber: Despite the concentration of sugars, raisins retain a significant amount of dietary fiber (around 4% by dry weight) [1]. This insoluble fiber promotes gut health by aiding digestion and promoting satiety (feeling full) [3].
Mineral Menagerie:
- Potassium Powerhouse: Raisins are a rich source of potassium (around 750 mg per 100 g) [1]. This essential mineral plays a critical role in maintaining healthy blood pressure by regulating the balance of electrolytes within the body [4].
- Iron Fortitude: Compared to fresh grapes, raisins exhibit a higher concentration of iron (around 2 mg per 100 g) [1]. This vital mineral facilitates oxygen transport in the body by being a key component of hemoglobin in red blood cells [5].
Vitamin Vault:
- B-Complex Bounty: Raisins are a good source of B vitamins, particularly thiamin (vitamin B1), riboflavin (vitamin B2), and niacin (vitamin B3) [1]. These B vitamins are crucial for energy metabolism, nervous system function, and overall cellular health [6].
- Vitamin K for Coagulation: Raisins contain a modest amount of vitamin K (around 10 mcg per 100 g) [1]. This vitamin plays a vital role in blood clotting and maintaining bone health [7].
Biochemical Delights:
- Antioxidant Arsenal: Raisins are brimming with phenolic compounds, a class of natural antioxidants. These antioxidants help combat free radicals, unstable molecules that can damage cells and contribute to chronic diseases [8].
- Osmotic Odyssey: The drying process of raisins exemplifies the principle of osmosis. As water evaporates from the grape, the concentration of solutes (sugars and other dissolved molecules) inside the fruit increases, creating a hypertonic environment [9]. When placed in water, water molecules naturally flow from an area of low solute concentration (the water) to an area of high solute concentration (the raisin) in an attempt to achieve equilibrium, causing the raisin to rehydrate and plump up [9].
Glossary:
- Carbohydrate Concentration: The process of increasing the proportion of carbohydrates in a substance by removing water.
- Glycemic Index (GI): A ranking system that assigns a value to foods based on their blood sugar impact.
- Insoluble Fiber: A type of dietary fiber that does not dissolve in water and promotes gut health.
- Electrolytes: Minerals that conduct electricity in the body and are essential for maintaining fluid balance.
- Hemoglobin: The protein in red blood cells that carries oxygen throughout the body.
- B-Complex Vitamins: A group of B vitamins essential for various cellular functions.
- Antioxidant: A molecule that helps protect cells from damage caused by free radicals.
- Hypertonic Environment: A solution with a higher concentration of solutes compared to another solution.
- Osmosis: The spontaneous movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.
By delving into the scientific details surrounding the raisin, we gain a deeper appreciation for its nutritional value and the fascinating interplay of biological and chemical processes at work within this tiny dried fruit.

Math Movies
Math Movies For Really Light hOmewok
- Jurassic Park (1993) – A mathematician (Jeff Goldblum) is among those invited to a theme park with cloned dinosaurs, in order to assess its safety.
Intro: Jeff's Character is an expert in
Choas Theory, a math theory that is used in art, history, philosphy,
sports and modern architecture and of course studies into time travel
and not so much dnosaurs.
- 21 (2008) – A group of MIT current and former students, mostly mathematicians, and a mathematics professor devise a card counting scheme for success at Las Vegas Strip blackjack tables.
Card counting is an an advanced form of
probability, which actually gives the math student the advantage.
Anyone can do this.
- The Bank (2001) – A mathematician discovers a formula to predict fluctuations in the stock market.
Math is now used as standard by stock
brokers to do what is shown in the movie. Mathematics
is always tiring to find the next
superior theorem.
- Cube (1997) – Six people, including Leaven, a maths student, awake in a deathtrap based on mathematical principles.
A fun Canadian Movie. Very basic math.
Sneakers
(1992) – An eclectic team is assembled to steal a code-breaking box
developed by a rogue mathematician.
A fun spy movie with real math
concepts, Hollywood style.
- Moneyball (2011) – Oakland Athletics baseball team's general manager Billy Beane attempts to assemble a competitive team using statistics.
True story. True use of Math Watch.
A movie about the battle beteween the
average folk vs. the mathematics - which ended with 1000 years of
darkness and misery as ignorance becomes the norm.
- Good Will Hunting (1997) – Janitor and super-genius Will Hunting (Matt Damon) begins to turn his life around with the help of psychologist (Robin Williams) and a Fields Medal-winning professor (Stellan Skarsgård).
- A true story. The math is not core to the film other than the character is a genius.
Enigma
(2001) – A story of romantic and psychological intrigue set in
Bletchley Park
during the World
War II effort to crack the German Enigma
machine.
Recently DE-classfied, the machine that
won the war. After the machine was invented it was
impossible for the allies to lose the
war, as long as Turin's equations where followed. IT is also the
first modern day computer - though with modern mathematics and new
age of computers will make modern computers look like cave drawings.
Modern computers are millions of times better than Turin's machine,
and Quantam computers will be (if they work) be billions of times
better than our best computer now. They will make most professions
obsolete as every single computer on earth will have the power of
googe wihout being on the internet (instantaneous langague
translation for example) This is done via mathematics and algerba.
Woodworking Courses

With means more blessed than my barren rhyme?
Now stand you on the top of happy hours,
And many maiden gardens, yet unset,

Which this, Time's pencil, or my pupil pen,
Neither in inward worth nor outward fair,
Can make you live your self in eyes of men.
To give away yourself, keeps yourself still,
And you must live, drawn by your own sweet skill.

On Kings and Country:
O Prince, O Chief of many Throned Powers,
That led th' imbattelld Seraphim to Warr
Under thy conduct, and in dreadful deeds [ 130 ]
Fearless, endanger'd Heav'ns perpetual King;
And put to proof his high Supremacy,
Whether upheld by strength, or Chance, or Fate,
Too well I see and rue the dire event,
That with sad overthrow and foul defeat [ 135 ]
Hath lost us Heav'n, and all this mighty Host
In horrible destruction laid thus low,
As far as Gods and Heav'nly Essences
Can perish: for the mind and spirit remains
Invincible, and vigour soon returns, [ 140 ]
Though all our Glory extinct, and happy state
Here swallow'd up in endless misery.
But what if he our Conquerour, (whom I now
Of force believe Almighty, since no less
Then such could hav orepow'rd such force as ours) [ 145 ]
Have left us this our spirit and strength intire
Strongly to suffer and support our pains,
That we may so suffice his vengeful ire,
Or do him mightier service as his thralls
By right of Warr, what e're his business be [ 150 ]
Here in the heart of Hell to work in Fire,
Or do his Errands in the gloomy Deep;
What can it then avail though yet we feel
Strength undiminisht, or eternal being
To undergo eternal punishment? [ 155 ]
Whereto with speedy words th' Arch-fiend reply'd.
Fall'n Cherube, to be weak is miserable
Doing or Suffering: but of this be sure,
To do ought good never will be our task,
But ever to do ill our sole delight, [ 160 ]
As being the contrary to his high will
Whom we resist. If then his ProvidenceOut of our evil seek to bring forth good,
Our labour must be to pervert that end
And out of good still to find means of evil; [ 165 ]
Which oft times may succeed, so as perhaps
Shall grieve him, if I fail not, and disturb
His inmost counsels from thir destind aim.
