How clean are your hands? I want you to carry out an experiment...
What you can’t see are the invisible-to-your-eye germs that gather on your hands throughout the day. To help you see the effect those germs have, give this this eye-opening experiment a try.
HAND HYGIENE EXPERIMENT
What you’ll need:
Three slices of bread
Three resealable bags
Instructions:
- Label each of the three bags:
- Control
- Dirty
- Clean
3. Remove a second slice of bread and touch the bread with unwashed hands. Place the bread in the bag and seal it.
4. Wash your hands with soap and water.
5. Take a third slice of bread and touch the bread with freshly-washed hands. Place the bread in the bag and seal it.
6. Take all three sealed bags and put them in a cool, dry place.
Look at the bread daily and write down your observations, but do not take the bread out of the bags. In a few days, mold should start to appear.
What slice of bread gets moldy first?
Which grows the most mold?
Which grows the least?
If mold starts to appear, take a ruler and measure it and record your observations. You can even draw a picture of the bread each day, or keep a photo diary by taking pictures of the bread each day to watch the changes over time.
