Soap vs. Sanitizer. HAND WASHING HAND SANITIZER. Al Abrar School Grade 4 Done by: Jihad Jaafar Aya Hussein Ali Al Rida Tahan Teacher: Rawan Shahla.
Introduction:. . After the large spread of the corona epidemic in the world, the World Health Organization (WHO) has announced the importance of using soap or hand sanitizer to get rid of the virus. But many people resort to using hand sanitizer as an alternative and quick solution instead of washing hands with soap and water..
Posed problem:. Which is more effective in reducing the amount of viruses on hands: washing with soap or using sanitizer ?.
Hypothesis:. Washing with soap show greater effect in reducing the amount of viruses on hands..
To validate our hypothesis w e did the following methods:.
Survey. We asked 10 0 students at Al Abrar School about their thoughts : Soap or Sanitizer is the solution for killing viruses?.
How viruses get onto hands?. Viruses are small beings that get onto hands if people touch any object that has viruses on it because someone coughed or sneezed on it or during the shaking of hands..
What is Soap?. Soap is a substance that is made from fat or oil used for cleaning. When combined with water, soap is able to wash away viruses..
What is Hand Sanitizer?. Hand sanitizer is a substance applied to the hands in order to remove common viruses. It come in foam, gel, or liquid form..
Worldwide Experiment. (Dirty hands/ hands cleaned by sanitizer/ washed hands) They used UV light and cream called Glo- Germ, that are able to capture how much dirt is on hands. They found that hand sanitizer is effective but not as hand washing with soap..
Experiment. Materials: Soap Sanitizer Bread Plastic bags Scissors Tongs.
Experiment. Procedure: Take a piece of bread by the tongs and put it in the first bag. Add the second one with dirty hands to the second bag. Clean your hand with sanitizer and put the bread in the bag. Take the last part with clean hands washed by soap and water and add it to the bag..
Observation:. Days Day 1 Day 3 Day 6 Without touching nothing happened Dirty hands nothing Use sanitizer nothing With soap and water nothing.
Analyze:. Soap destroy s the surface membranes of the virus ; then form micelles around its fragments which are washed away when we rinse our hands with water. Applying hand sanitizer may be easier, but even the ones with sufficient alcohol content (60% alcohol) cannot remove all types of viruses..
Conclusion:. We conclude that Soap and water are far more effective than sanitizer at reducing the amount of viruses..
Recommendations:. If soap and water are not readily available, use hand sanitizer that contains at least 60% alcohol , and wash with soap and water as soon as you can. Handwashing isn’t a one-and-done exercise. Good hand hygiene throughout the day is vital to protecting your health as well as that of others..
