A control group is a group of test subjects that receive a standard treatment or is not experimented on at all.





The experimental group is the group that receives the ';special'; treatment.


If the independent variable (type of water received) had its supposed effect, that effect will be reflected as the difference between the control group and experimental group.





So your report would be like this:





e.g AIM and Hypothesis:


To find out what effects Sprite, water and tea have on seed germination


We hypothesize that a seed that receives water will germinate the best.





As a control, a seed is given nothing.


Seed 1,2 and 3 is given water, sprite and nestea.


this is your experimental group.





Results: (write whatever happened)
