This is an example of a simple scientific investegation.It starts with an initial observation which is the shower is covered with green slime.Then,from this observation a suggestion of her friend,Karen was able to come up with a question or scientific problem that is,"Can coconut juice get rid of the green slime?"Out of this question,Karen came up with hypothesis,"If coconut juice is sprayed on the shower,then
the green slime will be removed." He then conducted an experiment wherein half of the shower was sprayed with coconut juice and the other half of the shower was sprayed with coconut juice and the other half with water.The shower sprayed with coconut juice is thw experimental group the control group.The control group serves as the basis for whether the treatment applied to the experimental group has an effect .After three days,the results showed that three in no change in apperance in the both groups.Thus,the hypothesis is rejected.Karen can conclude that the coconut juice has no effect on thw green slime in the shower.Specifically,we can say that coconut juice cannot remove the green slime on the shower.
