Egg osmosis experiment Shera 8-16
- 2. Purpose • To observe osmosis in a cell. 1. Place eggs in vinegar to remove the shell. 2. Measure weight of the egg using a balance. 3. Measure the size of the egg using string and measuring tape. 4. Place one egg in corn syrup, place the other egg in water. 5. Weigh and measure the eggs again
- 3. Hypothesis • Corn Syrup Egg • I think it will get bigger, heavier and look larger • Water Egg • I think that it the weight, size and appearance will stay the same
- 4. Materials • Eggs • Balance • Measuring tape & string • Corn syrup • Water • Two beakers • Vinegar
- 5. Observations 1. There are bubbles rising Before After from the egg to the top of the vinegar 2. There are more bubbles at Corn Syrup W. 67g W. 44 the top and the egg is S. 16.1cm S. 13.2cm floating 3. Eggs are still floating and foam is forming at the top H2O W. 77.4g W. 91.9 4. After sitting in corn syrup S. 16cm S. 17.5cm overnight, it looks shrivelled up. 5. After sitting in water overnight, the egg sunk and became larger.
- 6. Conclusion • Water moved into the water egg making it larger • The egg had a lower concentration of water than the water • Water moved out of the corn syrup egg making it smaller • The egg had a higher concentration
- 7. Conclusion • My hypothesis for the water egg was wrong • Weight: I thought that the weight would stay the same but it got larger • Size: I thought that the size would stay the same but it increased • Appearance: I thought that it would look the same but it appeared bigger
- 8. Conclusion • My hypothesis for the corn syrup egg was wrong • Weight: I thought that the weight would increase but it decreased • Size: I thought that the size would get larger but it ended up getting smaller • Appearance: I thought that egg would appear larger but it shrivelled up
