We believe Floam Slime will collect the least amount of bacteria because there is the least amount of slime and more floam therefor there is less density and motion.

We believe that Clear slime will collect the most amount of bacteria because it is sticky and therefore the stickiness will result in bacteria overload.

We researched the types of slime and chose five types of slime we thought would harbour bacteria differently. The five types of slime we chose were: Water, Cloud, Clear, Floam, and Butter. We also researched the highest rated petri dishes. We did the experiment twice, using both homemade agar and commercial agar. No bacteria grew in either situation. We were going to research the types of bacteria that grew but there weren't any.

Dependent variable Our dependent variable is how much bacteria grows on each slime. 

Control variable We are going to put a small potion of each slime aside to see how much germs it grows on its own. 

Independent variable For our independent variable we changed the type of slime per day.

Day #1 observations 

• Clear and floam slime when warm get really sticky 
• The cloud slime flaked whenever rubbed against the agar or our hands 
• The agar broke/ripped easily
• The agar smelt bad 

(This is the day that we actually put the agar in the petri dishes and rubbed the slime on them so there will be no observations about the bacteria for this day)

We observed the petri dishes for 3 weeks and found that no bacteria grew in any of them.

In conclusion, we found that none of our slimes grew any bacteria. This surprised us because we thought that the germs would grow due to all of the bacteria that was on our hands when we played with the slime. Why didn't it work? Some reasons why we think it didn't work include: the slime counteracts the agar mix, the slimes are anti-bacterial, there wasn't enough bacteria on our hands, the slime wasn't exposed to the agar long enough, and it was too cold for bacteria to grow.\ What could we try different next time? Next time we could: rub a finger on the agar to show how much bacteria we have on our hands, use different germ inducing items, leave a small piece on the petri dish to increase exposure time.

If bacteria didn't transfer to the slime (as observed by no bacteria growing in the petri dish) then it's possible that smile is cleaner than we thought and that you can play with it multiple times without it being a bacterial playground.

This also applies to how parents sometimes won't get their kids slime because they think it will collect too many germs and that it will get their child sick. Perhaps we've shown that this is not the case and is false.

Clear pink slime sample 3 was opened by colleague may have cross contamination  Floam slime preparation was inconsistent resulting in smaller samples. Sterilisation station may be partly ineffective  Inoculation procedure may not be identical  Color and scent of slimes
