3. Once the water on the stove is boiling, drop the metal into the pot and let it sit there for about 5 minutes. This will heat the metal to the temperature of the boiling water (100.0°C). 4. While the metal is heating, nest one Styrofoam cup inside the other.…
Experiment 2- Wear goggles and apron at all times. Light the candle with the matches. Put the water into a bowl. Wait for 60 seconds and then blow out the candle. Pour the candle wax into the bowl of water.…
The process of heat-treating Knife River Flint requires a lot of time, preparation, and materials. The Knife River Flint that was used in this experiment came from Mercer County, North Dakota, which there are five different Knife River Flint Quarries in Mercer County. The three closest quarries to where the Knife River Flint in this experiment was collected are the Crowley Quarries, Medicine Butte, and Dodge Quarry. With the help of Russell Redhorn, a Native American monitor I was working with at the time, we were able to collect a large quantity of Knife River Flint cobbles from an area about eight miles south of Zap, North Dakota.…
Introduction: For this lab, the two main topics are surface tension and pennies. Pennies are a part of the US currency, which holds a value of one cent. They were mostly made by copper until 1982 when the government realized the expenses of using copper; thus, the composition was changed to 97.5% zinc and 2.5% copper or copper plated zinc. It has a diameter of 19.05 mm and a thickness of 1.52 mm and is forged using four procedures: Blanking, Annealing, Upsetting, and Striking. The design of the penny holds two alternative sides (heads or tails) which has a picture of Abraham Lincoln engraved on one end and a variety of pictures engraved on the other end (usually the white house).…
In the CNN article “How Tap Water Became Toxic in Flint, Michigan”, by Sara Ganim and Linh Tran, the write about how water became infected with lead in Flint, Michigan. In 2014, the city of Flint, Michigan, decided to cut the water supply of the city from Lake Huron to The Flint River. The city did this in order for the state to build a new supply line from the lake. When the water started coming in from the river, residents reported that it looked brown. It was discovered that the state DEQ wasn’t treating the water with an anti corrosive agent, and since the water from the river is 19 times dirtier than the water of the lake, the water corroded the metal of the pipes, putting it in the water.…
The NASA Antares Rocket exploded out of the air, after it was clearly safe to launch. 5,000 pounds of supplies and more than 200 million dollars were wasted. Heading to the space station on the rocket were several experiments given by the Chinese, Russians, Americans, and Australians. They were supposed to be tested in space to examine their effects in space however, after the explosion, the experiments need to be returned back to each country accordingly. The Chinese will get LB (mineral oil), MD (aluminum), WC (oak), and PA (corn starch); the Russian people shall receive LC ( isopropyl alcohol), MC (brass), WA (poplar), and PC (salt); the people of the U.S. will receive LE (corn syrup), MF (lead), WB (balsa), and PF (sucrose); the Australian…
Introduction A flam e tornado is pretty self-explanatory, it is just a flame being spun in circles{explain how fire tornados are created and what they are, maybe talk about them in the real world}The fire tornado works by “the rotating screen [giving] the air molecules an initial spin (called angular momentum or rotational momentum). The rotating air molecules collide with the hot air rising from the fire and the flame twists into the shape of a tornado” (“Steve”). Fire tornados actually happen in the real world, most commonly found during forest fires when winds blow in between trees. I tested to see if increasing rotational speed and adding vents to the bowl would increase flame length because both would promote air flow, which would allow…
In preparation for this experiment, all the experiments were conducted in the same room which was my garage. The garage was closed and was kept at a constant temperature. Any obstructions from the room that were on the floor were removed and the entire floor was swept. The same ball type, Bridgestone B330, was used during the experiment. Each ball was brand new and didn’t have any indentations and scuffs.…
Staff, We are looking to expand distribution of Shiney’s Scarves into 3 additional countries; China, Mexico and Sweden. All of our scarves are colorful and have an inspirational design or message embroidered on them. In order to honor the diverse range of cultures of the countries that we will be bringing our scarves to we must understand each countries tradition and symbolism of colors. As far as China goes, the color red is associated with good fortune therefore a red colored scarf with kanji symbols relating to good fortune will most likely be our top sellers. Green and purple scarves will be our second largest stock green is linked with life and purple denotes love.…
The purpose of this experiment was to calculate the percent yield of copper after conducting series of chemical reactions. To study the % yield of copper in the copper cycle, the initial mass and final mass of copper was measured. The chemical reactions involved in the copper cycle are dissolution, precipitation, dehydration, and oxidation/reduction. First, copper was reacted with in a beaker to form (aq) and .…
Our lab was composed of burning iron wool, measuring the initial mass and then the final mass to see how much mass it gained from the added oxygen. The iron wool was first rolled into a ball, not too firmly packed but not too loose. The point of this was one to make sure the individual strands were tangled up well enough, so that any sparks of burnt wool do not pop off, and so that the oxygen (after burning) could reach all the way to the inside stands of the wool ball. Thus, bringing us to our first error: sparks of wool flying off during the burning process. In this experiment, we did not attempt to control the sparks flying off which led to the wool losing mass.…
Going back to what I said in the paragraph before. I also did this experiment to tell which color of candle to buy light or dark colors. The only background research I did was to figure out why lighter colored candles don’t burn as long. Engineering.com gave me a great answer for this.…
Determining The Process of Photosynthesis And Cellular Respiration Using Elodea and Yeast Introduction Photosynthesis is an essential process to life on earth, in which plants and other organisms use sunlight to create food from oxygen, and carbon dioxide. Cellular respiration is when energy in food is released and converted to ATP, which is then used as chemical energy to complete tasks within a cell. This process usually requires oxygen and releases carbon dioxide. Photosynthesis and cellular respiration are similar in some areas and different in others. The purpose of both of the process is to produce energy, but they have different ways of achieving this goal.…
In this experiment, two cations in an unknown solution were found using qualitative analysis. For Part A, the solution was to contain either silver or lead, while in Part B, the solution that was set on the side form Part A was identified to contain either calcium or barium. Part C explored a different method through the use of cation flame tests to observe colored flames from six metal chloride solutions. In Part A, the initial step was to add HCl to the unknown sample.…
We carefully weighed the crucible, cover, and magnesium ribbon together. The total mass was recorded. Next, we heated the crucible with the magnesium in it, but we left the cover aside. When the Magnesium started to burn, we put the cover back on to put out the fire. We continued to heat the crucible for a minute before taking off the cover.…
