Hypothesis: If I test 3 different types of padding to protect an egg when it is dropped, then
the bubble wrap will provide the most protection to the egg
.
What is the hypothesis of a bouncy egg?
The membrane of a chicken egg is
selectively permeable
. The vinegar is able to cross the selectively permeable membrane of the egg through osmosis. The vinegar toughens up the membrane of the egg making it bouncy!
What is the egg hypothesis?
Under the EGG hypothesis,
if the human reproductive system poses a dilemma between competing needs
, then fetal energy needs and maternal energy supply are the competitors, rather than encephalization and bipedalism.
What is the science behind the egg drop experiment?
The science behind solving the falling egg “problem” is found in
Sir Isaac Newton’s laws of motion
. … If you let go of the egg, gravity becomes an unbalanced force and causes the egg to fall to the ground.
What is the conclusion of the egg drop experiment?
Conclusion (1 paragraph): The Drop
The container protects the egg because it is packed with bubble wrap
. When the package hits the pavement, all of the tiny bubbles of air should protect the egg from being damaged.
Why does vinegar dissolve egg shell?
Eggshells are made of calcium carbonate. If you soak an egg in vinegar the
eggshell will absorb the acid and break down
, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air.
What does coke and vinegar do to an egg?
The little bubbles you see in the water are made of carbon dioxide gas; just like the bubbles from your vinegar and baking soda volcano. Once the shell is gone,
the vinegar will cross over the semi-permeable membrane
(through a process called “osmosis”) and slightly inflate the egg.
What happens when you put an egg in Coke for 24 hours?
After the Coca Cola and egg was left for a year,
the soda reacted with the egg shell made up of calcium carbonate reacted with the acid
and the result was surprising. … If this is the reaction of the egg shell and Coca-Cola, consider what it can do to your teeth and how it can erode and destroy the enamel of your teeth.
What happens if you leave an egg in vinegar for too long?
What happens? Be careful, the eggshell will be a lot weaker! If you leave the egg in the vinegar for about 36 hours,
eventually all the calcium carbonate will be dissolved by the acetic acid, leaving just the soft membrane and yolk behind
.
What makes an egg bouncy?
The Science Behind It: The shell of an egg is made of calcium carbonate! When the egg is placed into the vinegar, you see bubbles, which is the
chemical reaction of the acid within the vinegar reacting with the calcium carbonate of the egg shell to produce carbon dioxide
.
What do you use for the egg drop experiment?
- Raw egg, or other payload that needs protecting.
- Container, like a cardboard tube, cup, box, etc.
- External protection materials, like balloons, rubber bands, craft sticks, straws, etc.
- Internal padding, like fabric, packing materials, paper, etc.
- Pen or pencil.
- Paper.
- Tape.
- Scissors.
How do you win an egg drop experiment?
- Slow down the descent speed. …
- Cushion the egg so that something other than the egg itself absorbs the impact of landing. …
- Orient the egg so that it lands on the strongest part of the shell.
What are the best materials for an egg drop?
- Masking tape.
- Balloons.
- Straws.
- Cardboard.
- Cotton.
- Toilet paper.
- Socks.
- Plastic bags.
What is the best way to protect an egg in an egg drop?
Possibilities include
balloons, popcorn
, packing peanuts, wads of paper or cereal puffs. Encase the egg in any of these inside a paper or plastic bag, a sock or a stocking. If you have any bubble wrap around the house, wrapping the egg in several layers of bubble wrap should also provide a good cushion.
How do you slow down an egg drop?
To slow down the egg, you need to
increase the surface area
– the larger the area, the more that air resistance acts against the egg. One effective way of doing this is to add a parachute, which increases the surface area significantly.
Why doesn’t an egg break when dropped on a pillow?
If you drop another egg from the same height onto a pillow it wont break (better get a grownup to help with this). … The egg dropped on the pillow slows down and stops more slowly since the pillow is squishy, therefore
the force on the egg is smaller
and the egg does not break.
