PURPOSE To observe osmosis in a cell Place eggs in vinegar to remove the shell Place egg in vinegar Measure the weight of the egg using a balance Measure the size of the egg using string and measuring tape Weight and measure the eggs again
HYPOTHESIS Corn syrup egg Water egg Weight- I think that Bob will get Weight- I think that Steve will besmaller in weight more in weight Size- I think that Bob will get Size- I think that Steve will besmaller in size bigger in size Looks- I think it will look a little Looks – I think that Steve will looksmaller like it’s bigger and like jelly.
OBSERVATIONS 1)There is bubbles rising to the top of the egg 2)More bubbles at the top and eggs are floating 3)Eggs are still floating and has foam forming at the top
OBSERVATION Before After 4) After staying in corn syrup for 24 hours , the egg looks shriveled upCorn Syrup W: 67 g W: 44g Egg S: 16.1 cm S: 13.2 cm Water W: 77.4 g W: 91.9 g 5) After sitting in water for 24 Egg hours the eggs have sunk and look S: 16 cm S:17.5 cm larger
CONCLUSION Water Egg Got larger Lower concentration Went from high concentration to low concentration Syrup Egg Got smaller Water moved out of the egg Went from low to high concentration
CONCLUSION Water egg- My hypothesis was correct for the water egg because.. I said the weight would be more. Also increased in size and it lookedbigger. Corn syrup egg- My hypothesis was also correct for the corn syrup egg because…I said the weight would be less. Also decreased in size and it size and itlooked smaller.
