Science Projects With Soda By Lesley Henton The physical properties of soda can make for some educational and entertaining science projects. Even different types of soda can cause varying reactions under the right conditions.
Notebook and paper Procedure: Give your pennies a drink! Collect some old, dull and tarnished pennies for this experiment. Create a hypothesis, your best guess about what is going to happen. What do you think will happen to the pennies when you leave them in cola bath overnight? Take a picture of your pennies.
Line them up in order according to the dates on the penny. Take a photo of them with a piece of white paper as the background. Now your pennies are ready to take a bath. Before bed, come back to your experiment and flip the pennies over. Take the pennies out of their bath and wash them off.
Line them up in the same order you did before you bathed them, and take another photo.
After a day in the cola bath, the pennies will be very shiny. There are lots of stories about the amazing powers of soda and the not-so-amazing effects of soda on your body. Some are true—others are not.
So why can soda, particularly sugary colas, make pennies shiny? In a chemical reaction, two different chemicals change each other. Part of the reason the pennies change has to do with the pennies, and part of the reason has to do with the cola. Pennies are made out of copper, and after a while, copper gets dull.
This is because the copper in the pennies reacts with air to create copper oxide. Yes, there are chemical reactions going on all over the place! Copper oxide looks less shiny than plain copper.
If you had to describe the taste of cola, you might describe it as tangy. Most colas have a pH of 2.
The scale for pH is a way to determine how acidic something is. It goes from 0 to 14, and everything under 7 is acidic. This means that cola is quite acidic! Vinegar has a pH of 2.
When the copper oxide the pennies and the phosphoric acid the cola get together in the bath, the acid reacts with the copper oxide on the pennies and dissolves it. What else could you put into the cola bath?
What do you think will happen to them when they sit in a cola bath overnight? Disclaimer and Safety Precautions Education. In addition, your access to Education. Warning is hereby given that not all Project Ideas are appropriate for all individuals or in all circumstances.

In this cooking and food science project, the student will experiment with different ratios of baking soda, citric acid, and sugar to develop a delicious soda pop. It is the perfect time to start a plant-themed science fair project because there will be sufficient time for the plants to grow by a measurable amount.
Plant projects also automatically earn extra points for effort because they are an example of a project that could not have been done the night, or even weekend, before the due date.
