Science Concept & Application
For my experiment, the first thing I did was find a bottle or jar. I just used a Gatorade bottle that has been sitting in my car for a couple of weeks. I then cleaned out the Gatorade bottle with just some soap and water. I also needed to tear the label off but if you were to use a mason jar you would not need to do that. I then filled it up halfway with water and food coloring used Great Value vegetable oil and filled the rest of the bottle up. Then I opened the regular Alka-Seltzer tablet and broke it in half and put it in the bottle with the water and vegetable oil. Sit back and watch it bubble. I also am doing the different kinds of Alka-Seltzer tablets so I did that again but with the Alka-Seltzer extra strength, fizzy melts, and the off-brand Picot.
Well, first the different kinds matter because they contain varying combinations of active ingredients, designed to target specific symptoms like heartburn, pain relief, or cold/flu symptoms. With that being said you should choose the type that best addresses your current need, whether it’s just basic antacid or something more comprehensive like pain relief with added decongestants. Here are the different kinds of Alka-Seltzer tablets that I used basic Alka-Seltzer tablets, extra strength, fizzy melts, and even an off-brand called Picot. If you take too much Alka-Seltzer it could just make you sicker than you already were. I learned quite a bit of things like how Alka-Seltzer tablets make good lava lamps and how taking too much of the wrong medicine can be very harmful. I also learned how different types of tablets react with water and vegetable oil. The original “lava lamp” design, which uses a combination of oil and water with heat to create the flowing effect, was invented by Edward Craven-Walker. |
Career
Chemists play a crucial role in various industries, applying their knowledge of chemical composition, structure, properties, and reactions to develop new products and solve real-world problems. They might work in research and development, synthesizing new pharmaceuticals or materials, or in quality control, ensuring the purity and safety of manufactured goods. Analytical chemists analyze substances to determine their composition, while environmental chemists study the impact of chemicals on the environment. Some chemists specialize in specific areas like biochemistry, studying the chemical processes within living organisms, or physical chemistry, exploring the physical principles underlying chemical reactions. Their work often involves conducting experiments, analyzing data, and collaborating with other scientists and engineers.
The salary of a chemist can vary significantly depending on factors like education, experience, industry, and location. Entry-level positions typically require a bachelor's degree in chemistry and may offer salaries in the range of $45,000 to $60,000 per year. With a master's degree or a doctorate, chemists can access more specialized roles and higher earning potential, often exceeding $80,000 annually. Experienced chemists in leadership positions or highly specialized fields can earn well over $100,000 per year. Industries like pharmaceuticals and biotechnology tend to offer higher salaries compared to other sectors. Scientist
Henning Brand is a German chemist who, through his discovery of phosphorus, became the first known discoverer of an element. He was a military officer and a physician. He was born in 1630 and died in 1710. He married a wealthy wife whose sizable dowry enabled him to fund his alchemical research. His wife then died and he married another wife, Margaretha, after the death of his first wife.
Henning Brand was obsessed with discovering the philosopher’s stone. The philosopher’s stone could turn common metals into gold. Bran grew to believe that human urine offered a gateway to the philosopher’s stone. Brand collected thousands of liters of urine from his neighbors. In 1669, Brand evaporated the urine he collected in Hamburg to yield a black sludge. He left this to mature until worms started appearing in it. He heated the sludge with sand, yielding hot gases and oils, which he condensed using cold water. The final substance to condense was a white solid. This was phosphorus. (Human urine contains significant quantities of dissolved phosphates.) |
