The hypothesis is that antibacterial soap will kill more bacteria than normal soap.

You will prepare petri dishes with blood agar, collect saliva, and mark chopsticks. You will then dip the chopsticks into the saliva and wash them with antibacterial and non-antibacterial soap for different lengths of time. Finally, you will measure the size of the bacteria colony growth.

You will need 4 petri dishes with blood agar, some human saliva, 4 disposable chopsticks, a ruler, antibacterial soap, non-antibacterial soap, a stopwatch, a disposable cup, and a permanent marker pen.

The results showed that the antibacterial soap was only effective in killing all the bacteria if the chopstick was washed for more than 2 minutes. The non-antibacterial soap was not as effective as the antibacterial soap. This experiment proves that antibacterial soap is more effective in killing bacteria than regular soap.

This science project is interesting because it tests the effectiveness of antibacterial soap against regular soap in killing bacteria. It also shows that washing our hands with warm water and regular soap is sufficient to ward off infections.

Variations of this experiment include touching the petri plate with a finger instead of using saliva, and repeating the experiment under different room temperatures and/or lighting conditions.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
