2. Materials Coke Sprite7 bowls with lidsVinegarE2 juice
PoweradeOrange juice 7 eggs Water 3. Method 1.Get 7 of the same
containers and place them on a bench in the same area. 2.In each
container put 1 egg - this needs to be the same size and
brand.3.Pour the same amount of liquid in each. Measure this
carefully as it needs to be exact.1 with coke, 1 with vinegar etc.
4.Put lids on each container. 5.Wait for three weeks and watch the
magic happen. Do not move or fiddle with as this might change the
outcome. 4. Aim:We want to find out which liquid can make an egg go
squishy and bouncy the fastest. 5. Our hypothesisWe think that the
vinegar will dissolve the shellbecause the acid in the vinegar will
melt the egg shell and make it rubbery. 6. Results: The vinegar has
won but Hugh popped it. The vinegar had made all the calcium come
off the shell.The orange juice came second but it did the same as
the vinegar but it tooklonger.The e2 juice came third because it
made the shell squishy but not that fast. The coke came fourth
because the shell broke when Hugh picked it up because it was a bit
rubbery.The powerade came fifth because he made the shell red and
all rocky.The sprite came sixth because it made the shell brown.
The water came last because it did nothing. 7. Conclusion:Our
hypothesis was right because we guessed that the vinegar would
winbecause it is made of acid. 8. Discussion/reflection:We found
out that the coke takes exactly one year to make it rubbery. The
vinegar only did it in two weeks. We found out that the vinegar can
make anegg shell go rubbery and so does the orange juice. Next time
if we did it againwe would leave the vinegar in there longer and
see if it would completelyvanish the egg. 9. Heres what
happened:Several things happened to the eggshell while it was
soaking inthe vinegar. The vinegar is an acid and it caused the
shell materialto breakdown into two different materials. One is
carbon dioxidebubbles that were released into the air. The other
material is lime. The lime remains in the solution. Also, the
appearance of the shell changes the result of this chemical
reaction. This is a fairlycommon process. It happens in nature a
lot, creating limestonecaves. This chemical reaction also attacks
your teeth. Yuck! Makes you want to go brush your teeth!Soaking an
egg in vinegar dissolves the calcium carbonate in theshell* leaving
the flexible membrane. The egg might bounce butwill more likely
simply splatter.
