How to Make a Lemon Battery. For this science fair project, kids will learn how to make a lemon battery. They can conduct this classic experiment using readily available materials. Is There a Connection? In this experiment, you will evaluate whether or not a diet that is supplemented with "brain-enhancing" foods can help improve memory.
This experiment investigates if small changes in your diet can alter your basal body temperature. This bread mold experiment will help your child learn about mold, and he'll develop important hypothesis-making and experiment-designing skills. Discover if soda geysers will erupt when using regular vs.
In this project, you'll create Oersted's experiment, which relates to how electric currents create magnetic fields. Can Food Boost Your Mood? This experiment evaluates how a diet that is rich in "mood-enhancing" foods affects the way people feel over several weeks. Experiment with the wonders of pressure and condensation by crushing a soda can with nothing but air and water! High school students recreate Michael Faraday's experiment in this cool science fair project that induces current in a coil of wire.
That means that all of the pieces of the reaction are there, but that they are simply rearranged. It also means changing some factors may cause a larger or smaller physical reaction to take place. Background A carbonated beverage is packed full of dissolved carbon dioxide gas, which forms bonds with water. While the soda is in the bottle, the gas is kept in solution by the bottle's pressurized conditions.
When you pour some soda into a glass, some gas escapes and forms foam, but most stays trapped by the surface tension of the water. But all those gas bubbles want to escape, making it no wonder that soda makes you burp! To create bubbles, the carbon dioxide needs to interact with itself, which means that the carbon dioxide's bonds with water in the Diet Coke must be broken. A Mentos candy can help with this.
Although the candy may look smooth, if you looked at it under a microscope you'd see tiny bumps coating its entire surface. This rough surface allows the bonds between the carbon dioxide gas and the water to more easily break, helping to create carbon dioxide bubbles and cause the classic eruption. The speed at which the Mentos falls through the soda can affect how large the eruption is, and this can be tested by comparing whole with crushed Mentos, the latter of which are less dense.
On the wax paper, carefully use a knife to crush and cut four Mentos candies into many small pieces. An adult may help you cut up the candies.
What does the inside of the candies look like? Tape the tube together on the side. Make sure that the bottle is on a level surface and stably standing straight. Why do you think all of this is important? Line up where the opening of the bottle is with the opening of your cartridge. Quickly pull out the flat index card, releasing the Mentos candies into the bottle. Then step back without tipping the bottle over or disturbing the reaction. About how high did the eruption go?
How much cola is left in the bottle? As with the first bottle, remove the cap and place the flat index card on top, covering the hole. Put on your eye protection and start the video camera. Quickly pull out the flat index card, releasing the crushed Mentos into the bottle, then step back without tipping the bottle over or disturbing the reaction. How high did the eruption appear to go? How much liquid is left in the bottle? Is it more or less than the amount that was left when you used whole candies?

Feb 09, · Kids love the dramatic Mentos and Diet Coke experiment conducted in this awesome science fair project/5().
Have you ever seen the Diet Coke and Mentos experiment that is all over the Internet and wondered what makes the reaction work? You might think that there is some ingredient in a Mentos candy that. Why do Diet Coke & Mentos and Coke Zero & Mentos create such exciting geysers? It’s mostly due to a process called nucleation, where the carbon dioxide in the soda is attracted to the Mentos (they are awfully cute). «Experiment #6: Coke & Mentos Gone Wrong! Watch Videos Featured Videos EepyBird Videos Try This at Home Appearances Fan.
I’m sure you have hear of soda erupting once Mentos is added to it. This experiment is fun and exciting and it has made us wonder about the science behind it. The Diet Coke and Mentos experiment (shown in action in Figure 1 below) is all over the Internet, but how does it work? You might think that there is some ingredient in a Mentos candy that is causing a chemical reaction with the soda, like the way baking soda reacts with vinegar. But this is .
