What would be the control group,experimental group and variables for this experiment? please help?

Im doing a science fair project due on Monday and i have most of it done but im not sure what the experimenta group, control group and variables would be please help.





My question is ';What substances affect tooth decay the most?';





to do it i put three eggs in three diferent containers, one with orange juice, one with coke and one with sugar water. can you help me please?What would be the control group,experimental group and variables for this experiment? please help?
One egg has to stay in regular water, that will be your control group. You can use it to compare it to the other eggs.


The variables are orange juice, coke and sugar water. The experimental group are the eggs that go into the orange juice, coke and sugar water.What would be the control group,experimental group and variables for this experiment? please help?
what is your hypothesis? this is needed to know the other three.
The variable is what liquid you put the egg in.


The experimental group seems to be all three (OJ, coke and sugar water).


A control group would be in normal water, or in air, or in your fridge.





Explanation: the variable is the thing which is different in each test.


The control group is the one which is not subject to your experiment or anything unusual. It is kept in ';normal'; conditions.


The experimental groups are those which you are testing.
control variable: what you should keep the same or different





independent variable: stuff that you directly change (rationed amounts for each test)





dependent variable: the way nature works like you cant determine which would be here the tooth decay ma-bobber
