Lava Lamp

Picture
​SCIENCE CONCEPT
The scientific concept behind an Alka Seltzer Lava lamp is a chemical reaction. In this case, there is a chemical reaction between the water and the seltzer. The tablet forms a gas with the water called carbon dioxide. The carbon dioxide rises to the top slowly through the oil and once it pops at the top, the oil blob sinks back down to start the process all over again. 
Alka seltzer tablets are similar to the acids in our stomachs. The acids in our stomachs break down food into smaller pieces which are easier to digest. Without these acids, it would be very hard to break down food. These chemical reactions are very important to us.
APPLICATION
Chemical reactions can be found all around us. They happen when bread is baked, when iron rusts, lighting a match, and many more. Without chemical reactions, our world would be very different. There wouldn’t be much clean air because there would be no photosynthesis. We wouldn’t even be able to digest food. 
    Chemical reactions happen when the bonds of atoms are broken down or formed. Chemical reactions are a very important part of our everyday lives. Chemical reactions are also essential to helping us understand God’s creation.

​CAREER
One career for a chemistry lover is a chemistry teacher. The average salary for a high school chemistry teacher is $53,493 a year. Chemistry teachers have to have a minimum of a bachelor's degree. Most chemistry teachers are in high schools or colleges. Chemistry teachers are in charge of teaching chemistry classes and overseeing labs.
​SCIENTIST
The branch of science that deals with an Alka Seltzer lava lamp is chemistry. One famous chemist is John Dalton. Dalton lived in the 1700’s. He was a chemist, meteologist, and physicist. He is mainly known for introducing the atomic theory. He also did a lot of work with atoms.

ESSAY
Alka-Seltzer Lava Lamp

Alka-seltzer. Water. Oil. Food Coloring. These simple household ingredients, when added together correctly, can create an amazing science experiment. All of these components when combined, form an alka-seltzer lava lamp. Because of the ingredients in the Alka-seltzer tablet, they create a basic chemical reaction with the water. The seltzer forms a gas called Carbon Dioxide. As the gas floats up to the surface it brings along blobs of oil and food coloring creating a captivating lava lamp effect.

To perform this process you first need to gather all of your materials. I used a mason jar, tap water, vegetable oil, blue food coloring, and original Alka-seltzer tablets. The first step is to put about three inches of room temperature water into the jar. The results can vary depending on the temperature of the water. After mixing in the food coloring, you should add about two inches of oil. A distinction of densities is a crucial factor. Because of the different densities, the oil will stay floating on the top of the oil. The oil is less dense than the water. Water is made up of two hydrogen atoms and one oxygen atom. Oil is a mixture of different and complex hydrocarbons, which are compounds mainly composed of hydrogen and carbon.


The addition of the Alka-seltzer tablets initiates the chemical reaction process. By breaking the tablets into smaller pieces it creates multiple reactions making the visual effects even better. The acids in the seltzer react with the water to form the carbon dioxide gas. Once the gas begins ot float up to the top, the fun has begun. The gas brings blobs of colored oil to the top which creates the lav lamp effect. 


This DIY lava lamp is very similar to the function of traditional lava lamps. In a standard lava lamp there is a wax mixture that when heated, become less dense that the water, making it float to the surface just like the carbon dioxide and the oil. Sometimes the wax mixture is also floating in mineral oil instead of water. Special lights are inserted into the base, making the blobs appear more vibrant and illuminating.


The two major components behind this experiment is density and a chemical reaction. The concert of density plays a big part in how this demonstration works. Most people think that density is how thick or heavy an object is. In the words of Inigo Montoya, “That word. I do not hink it means what you think it means.”( The Princess Bride 1987 a.k.a. The greatest movie of all times.)  Thickness and weight is only part if it. The density of an object is the mass of an object compared to its volume. This amounts to m/v or mass over volume. Density is also known as how tightly a material is packed together.


The density of water is 1 gram per milliliter but this can change depending on the temperature or other surrounding conditions. This is why hot and cold water won’t mix very easily. Additionally, this is why ice floats in water. Ice is less dense than normal water. The concept of density can also be applied into everyday life. For example, take the Pacific and Atlantic oceans. Where the two bodies of water meet, there is a very distinct barrier. You can notice a difference in color. The two oceans have a difference in desnistie due to temperature and salt content. Understanding density can be very useful for many different branches of science including chemistry, oceanography, and environmental science.


On the other hand, vegetable oil has a density of 0.92 g/ml making it less dense than water. It floats on top of the water with no issue. The gas is light with air making it float up through the water and the oil. The gas blob pops at the top allowing the water to go back down to start the process all over again.


The second component is a chemical reaction. Chemical reactions are found all around us. This particular chemical reaction is between water and an acid casuing the formation of a gas. The Alka-seltzer works the same way as the acid in your stomach. Alka-seltzer is mainly composed of citric acid and sodium bicarbonate. These two compunds cause a reaction with the water forming the gas, carbon dioxide. 


This is similar to what happens with yeast when bread is baked. The yeast forms a chemical reactions which makes gas bubbles causing the pockets of air in baked bread. This is why most bread has small holes and pockets. Another example is iron rusting. This is due to the reaction called oxidation. Oxidation happens when a process that occurs when atoms or groups of atoms lose electrons. This often happens due to changes in the amounts of oxygen. This gives the iron or similar metal a flaky surface. We call this, rust. Rust is just one other chemical reaction. There are hundreds of different chemical reactions that happen to and around us every single day.


Science can be fun an exciting. This expermient proves that. Science is very foundation to theis world. However, our world has tried to screw it up and has left God out of the picture.It becomes more important the older we get to show the real reasons behind science. Science and experimentation can be a great way to learn more about God’s creation and to show the world who is behind all of it.


In conclusion, the Alka-seltzer lava lamp experiment is a simple yet impactful way to explore scientific principles such as density and chemical reactions. By combing simple household materials one can create an intriguing lava lamp effect. Experiments and demonstrations can be fun and easy ways to learn more about complicated scientific topics. Science can be fun and a great way to learn all that we can about God’s amazing creation.
