Simple scientific experiments can be carried out at home with widely available equipment and materials. While children enjoy playing while learning, their knowledge can be expanded. Corn dancing in water is one of simple experiment. Corn doesn’t have arms or legs, so how can it dance in water? The secret to getting the corn dance is to use the right components. Let’s see what we’re doing:
Tools and Materials for Simple Experiment– Corn Dancing in Water
see-through glass
Tablespoon
Clean Water
Dry raw corn kernels (can be plain dried corn kernels or raw corn for making popcorn)
Vinegar
Baking soda
Steps to Make Corn Dancing in Water – Simple Experiment
Prepare a glass of clean water, just enough, you don’t need to be full
A tablespoon of vinegar can be added, or it can be dripped to taste.
Add corn kernels
Add a few more drops of vinegar
Add a tablespoon of baking soda, stir briefly
Watch as the corn kernels rise and fall, up and down the glass like a lovely dancer, once the vinegar and baking soda have been mixed and calmed down.
A few moments later, when the soda settles and the water clears, the corn grains will return to the bottom of the glass, and little bubbles will appear in the glass.
Explanation of the Simple Experiment of Corn Dancing in Water
Even though the glass and water are both stationary, how can maize grains dance in water? Because of a chemical reaction between vinegar and baking soda, this happens. When vinegar (CHsub>3/sub>COOH) and baking soda (NaHCO) combine, new chemicals are formed, including carbonic acid, sodium acetate, and carbon dioxide gas.
The maize kernels in the glass move up and down due to the carbon dioxide gas. A reaction occurs when carbon dioxide in the form of lighter bubbles from a mixture of water, vinegar, and corn kernels reacts with baking soda, resulting in corn kernels. The bubbles will burst as it reaches the water’s surface owing to contact with the outside air, and the corn will fall to the bottom of the glass.
Isn’t it amazing to watch maize kernels move in a vinegar and baking soda solution? However, this simple experimental corn should not be eaten. Because of the possibility that it was contaminated as a result of a chemical reaction.
