Controlled Variable- Science Fair01/07/2005 |
Hello. I have just e-mailed you yeaterday and I got your answer. Thanks! Do you think that I will have to do another experiment and find out how water effect the stained egg when brushing it with just water? If so, I will have to stain the eggs with my 6 different liquids for 10 days; so then that will be the 16th of January and my science fair is the 21! What should I do?! Thanks for your help and time!
I would do another experiment with just the control...brushing with water only. You need to have this as something to compare the other toothpastes to. Again, let me know the outcome of your science fair!
