What+Are+Germs?

  **Setting up the experiment: **   
 * “What Are Germs?” **
 * When mom or dad says, “Wash your hands!” or “Don’t catch any germs!” they want you to stay healthy. Germs are usually one-celled living things that live everywhere, even though you can’t see them. Some germs don’t bother us, while others can cause sicknesses like sore throats and the flu. In this project, we’ll try to grow germs into “colonies” (collections of germs) that are big enough to see. In this project, we will see if you wash your hands well enough. **
 * What We Need: **
 * Cheese 
 * Plastic wrap 
 * Paper towels 
 * A sharp knife or cheese cutter

 * <span style="font-size: 12pt; font-family: 'Corbel','sans-serif'; mso-bidi-font-size: 10.0pt; mso-fareast-font-family: 굴림; mso-bidi-font-family: Arial; mso-font-kerning: 0pt;">Cut three pieces from a new block of cheese in slices (Don’t handle the cheese very much when cutting). <span style="font-size: 11pt; font-family: 'Corbel','sans-serif'; mso-bidi-font-size: 9.0pt; mso-fareast-font-family: 굴림; mso-bidi-font-family: 굴림; mso-font-kerning: 0pt;">

Label it #1. <span style="font-size: 11pt; font-family: 'Corbel','sans-serif'; mso-bidi-font-size: 9.0pt; mso-fareast-font-family: 굴림; mso-bidi-font-family: 굴림; mso-font-kerning: 0pt;">

Put it next to the first piece of cheese on the plate and label it #2. <span style="font-size: 11pt; font-family: 'Corbel','sans-serif'; mso-bidi-font-size: 9.0pt; mso-fareast-font-family: 굴림; mso-bidi-font-family: 굴림; mso-font-kerning: 0pt;">

Dry them off with a paper towel. Handle the cheese again by rubbing your clean hands over it and place the last piece of cheese next to the others and label it #3. <span style="font-size: 11pt; font-family: 'Corbel','sans-serif'; mso-bidi-font-size: 9.0pt; mso-fareast-font-family: 굴림; mso-bidi-font-family: 굴림; mso-font-kerning: 0pt;">

We decided to place ours inside the cabinets. <span style="font-size: 11pt; font-family: 'Corbel','sans-serif'; mso-bidi-font-size: 9.0pt; mso-fareast-font-family: 굴림; mso-bidi-font-family: 굴림; mso-font-kerning: 0pt;">
