=Bandage or No Bandage?=
 * Do minor wounds (cuts, abrasions) heal faster with or without a bandage?**

===** One day I had fell and scraped my knee. I put a bandage on my cut. I asked my mom if I really needed to keep the bandage on for my cut to heal quickly, but she did not know. So I gathered up about 6 of my friends. I told them that a bandage helps heal cuts faster. To test this, I and my friends played outside until we all had at least one cut. I put my friends into 2 groups of 3. One group put bandages on their cuts, I called this Group A. The second group did not put bandages on their cuts, I called them Group B. The bandages were all the same size, same color, same shape, same brand, and they were all waterproof, as well. After about three days, I gathered all my friends together again to examine their cuts. **===
 * 1. A hypothesis: Cuts with bandages will heal faster than cuts without bandages. **
 * 2. Variables that must be kept constant during the experiment: **
 * ** bandage size **
 * ** bandage color **
 * ** bandage shape **
 * ** bandage brand **
 * ** waterproof bandages **
 * ** age of people **
 * ** health of people **
 * ** size of cut **
 * ** time cut was acquired **
 * 3. Independent Variable: **** The bandages. **
 * 4. Dependent Variable: **** How fast the cut heals. **
 * 5. Control Group: **** Group A, without bandages. **
 * 6. Experimental Group(s): **** Group B, with bandages. **
 * 7. How to set up your experiment: **
