Rapid Color Changing Chemistry!
By: Mya Miller, Sydney Holloway, and Mariah Fallon
Step 1: Ask A Question
Does the amount of Vitamin C added affect how fast the liquid turns blue?
Step 2: Do Background Research
This is an example of the chemical reaction know as the Iodiclock Reactionne. It is called a clock reaction because you can change the amount if time it takes for the liquids to turn blue. The chemistry of the demonstration gets a bit complicated, but basically it is a battle of chemistry between the starch which is trying to turn the iodine blue, and the Vitamin C which is keeping it from turning blue. Eventually the Vitamin C loses and, bam! - you get instant blueness.

Step 3: Construct a Hypothesis
Adding more Vitamin C will cause the water to change colors faster.
Step 4: Test Your Hypothesis by Doing an Experiment
Step 5: Analyze Your Data and Draw a Conclusion
Step 6: Communicate Your Results
Shared our experiments at our school science fair.
The more Vitamin C the more time it took for the water to change colors.
