Anmarie Somar 8-16 Egg osmosis experiment

  1. 1. EGG OSMOSISEXPERIMENT By Anmarie Somar 8-16
  2. 2. 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
  3. 3. 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.
  4. 4. MATERIALS  2 Eggs  Balance  Measuring Tape & String  Corn Syrup  Water  2 Beakers  Vinegar
  5. 5. 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
  6. 6. 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
  7. 7. 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
  8. 8. 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.
