The student conducted an experiment to observe osmosis in eggs. She placed one egg in corn syrup and another in water, then measured changes in weight and size. As hypothesized, the egg in water gained weight and size as water moved into the egg. The corn syrup egg lost weight and size as water moved out of the egg into the higher concentrated syrup. The purpose was to demonstrate how osmosis causes the movement of water across a semi-permeable membrane from an area of lower to higher concentration.
Every day, a lot of people all over the world participate in games and sports activities or competitions.
Participation in sports improves physical fitness and overall health and wellness. Games and sports can
also result in injuries, some minor, some serious and still other in lifelong medical problem. Sports
injuries result from acute trauma or repetitive stress associated with athletic activities. Sports injuries can
affect bones or soft tissue (ligaments, muscles, tendons). There are numerous sports injuries happened in
the field of sports. It is very important for all coaches, trainers and players to know the causes symptoms,
prevention and treatment for all these common injuries in order to avoid most of these types of injuries,

- Vitesse de fabrication volumique 2 l/h
- Accessoire ProX MQC pour la manipulation et le
recyclage automatisé du matériau
Welcome to the Program Your Destiny course. In this course, we will be learning the technology of personal transformation, neuroassociative conditioning (NAC) as pioneered by Tony Robbins. NAC is used to deprogram negative neuroassociations that are causing approach avoidance and instead reprogram yourself with positive neuroassociations that lead to being approach automatic. In doing so, you change your destiny, moving towards unlocking the hypersocial self within, the true self free from fear and operating from a place of personal power and love.
2. PURPOSE
To observe osmosis in a
cell
1) Place eggs in vinegar
to remove shell
2) Measure weight of egg
3) Measure size of egg
4) Place one egg in corn
syrup, other egg in water.
5) Weigh and measure
eggs again
3. HYPOTHESIS CORN SYRUP EGG
Corn Syrup Egg
Size will not change
Weight will stay the
same
Egg will look soggy and
sticky
4. HYPOTHESIS WATER EGG
Water Egg
Weight would be
heavier.
Size would be bigger
Egg will look fragile
and soggy
6. OBSERVATIONS
Before After
Corn Syrup W- 71.3 W- 48.8
S- 17 cm S- 13 cm
H2o W- 62.2 W- 77.0
S- 14 cm S- 18.5 cm
7. OBSERVATIONS (CONTINUE)
(after vinegar) Eggs at
the bottom.
Bubbles from eggs float
to top.
(after syrup 24 hours)
Floating, more bubbles,
and a bit of foam at the
top
(after water 24 hours)
More bubbles and foam
24 hours later, turned soft
and squishy.
Corn syrup egg =
shrivelled water egg =
puffy
8. CONCLUSION OF WATER EGG
Got larger
Water moved into egg
Egg had lower
concentration, water
had high concentration
Egg moved for lower to
higher.
9. CONCLUSION OF CORN SYRUP EGG
Got smaller
Water moved out
Egg had higher
concentration, syrup
had lower.
Water moved from
higher (egg) to lower
concentration
10. HYPOTHESIS
Corn syrup egg after
experiment:
Hypothesis was wrong
Got smaller by size and weight
Thought egg would stay same
Egg shrunk
Water in egg came out into corn
syrup to balance water in and out
of egg
Water egg after experiment
Hypothesis was correct
Egg got bigger and weight
Water entered egg because low
concentration
