IRIS Project by 2E2 Group 10

Iris (Life Science)

We study about  Iris because of a serious diarrhoea attack occured in Monforrt Secondary School that sent 25 students to the hospital. That why our teacher let us to research and investigate which area(s) has the higest occurrence of bacteria in the lab.

Location selected : Tap (sink)

Hypothesis

Tap will have the higest occurence of bacteria because many people have to turn the tap before they wash their hand with dirty hands with that bacteria might be come from some where else come to grow up in the tap, so the tap will have the highest of bacteria.

Independent Variable

The Location.

Dependant Variable

The way the bacteria grow.
Amount of bacteria.

Constant Variables

The type of argar gel.
The type of alchohal.
The temperature.

Observation

Location in the lab : Tap (Sink)

Description of colopnies present : The bacteria grow all over the argar gel but the colony also let some space of gel remain.

Conclusion

From the investigation, the area investigated in the lab

The tap is very dirty and full of bacteria because many people come to use it with their dirty hand and the tap is wet so the bacteria can grow easily and after thier wash their hand they have to turn off the water so they have to contact the bacteria again as they think thier hand are cleaned. So that might be the reason why a serious diarrhoea attack ocurred in Monfort Secondary school.
