Transcript of "Science Experiment 2"

  1. 1. EFFECT OF VINEGAR ON RAW CHICKEN EGG Done By: Leow Wei Sheng 2P315
  2. 2. CONTENT <ul><li>Hypothesis </li></ul><ul><li>Materials used </li></ul><ul><li>Method </li></ul><ul><li>Results </li></ul><ul><li>Explanation </li></ul><ul><li>Conclusion </li></ul><ul><li>Reflection </li></ul>
  3. 3. HYPOTHESIS <ul><li>The egg shell in vinegar will dissolve while the egg shell in plain water will not and the egg will become bouncy </li></ul>
  4. 4. WHY VINEGAR AND WATER? <ul><li>Vinegar is used to represent liquids with weak organic acid while water is used to act as a control </li></ul>
  5. 5. MATERIALS USED <ul><li>Two chicken eggs </li></ul><ul><li>Two identical containers </li></ul><ul><li>White vinegar </li></ul><ul><li>Water </li></ul>
  6. 6. METHOD <ul><li>Pour vinegar into one of the containers and water into the other container </li></ul><ul><li>Immerse one raw chicken egg into each of the container </li></ul><ul><li>Leave the setups at one corner and observe after two days </li></ul>
  7. 7. RESULTS <ul><li>The eggshell of the egg in the vinegar dissolved while the eggshell of the egg in water did not </li></ul><ul><li>The egg without an eggshell was able to bounce </li></ul>
  8. 8. EXPLANATION <ul><li>Eggshell is made up calcium carbonate, and the vinegar is a weak organic acid, ethanoic acid </li></ul><ul><li>When carbonate reacts with an acid, the products will be soluble salt, carbon dioxide and water </li></ul><ul><li>Thus the shell slowly dissolves </li></ul><ul><li>The only thing left holding the shell together is the egg membrane, which is flexible and stretchy, so the egg is able to bounce </li></ul>
  9. 9. CONCLUSION <ul><li>The egg shell dissolved as acid reacted with calcium carbonate, which is the eggshell </li></ul><ul><li>The egg without an eggshell bounces as the membrane holding it is flexible and stretchy </li></ul>
  10. 10. REFLECTION <ul><li>After doing this experiment, I found out how to make an egg bounce and the effect of acid on calcium carbonate. I also learnt how to manage time better, as I had to manage between this experiment and school work, especially when this time is an examination period and I also had to study. </li></ul>
  11. 11. <ul><li>Thank You! </li></ul>
