The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

As headlamps age, they continue to deteriorate and when one bulb fails, the 2nd bulb will most likely fail in the near future.

In this project, C. Elegans are hermaphrodite worms that will be used since they are easy to maintain in lab, as well as have short life cycles. The gene that the project attempted to knockdown in C. Elegans with RNAi treatment is the unc-22 gene. RNAi disrupts gene expression in the presence of double stranded RNA (dsRNA) that is complementary to target gene sequence. The unc-22 gene codes for a muscle protein called twitchin in wild-type worms. The Unc-22 is required for muscle regulation and maintenance in C.Elegans. To verify that the RNAi treatment worked, would check the unc-22 mRNA levels in the worms, in addition to phenotype observation.

Science is such a unique and highly captivating subject that so many young students find interesting and yet it is also a subject that the vast majority of students get discouraged by as well as lose interest in as they get older. There are so many different areas of science it is easy to be overwhelmed and get discouraged if you easily do not understand something. For this reason, I had decided I need to research a Citizens Science Project that I could bring not only bring into my future classroom but share with my students and their families as well.

This is done through a change in temperature. Over time, two objects that are in direct contact will

The students were able to relit the candle because they followed the stream of smoke was followed and carbon vapors and relights the already-hot wick. No experiment is perfect, during the candle lab many errors occurred. Some of the common errors that occurred during this lab were human, random, and systematic error. All of these errors could change the lab results.

October 17, 18, and 19, samples were collected from multiple sites along the BSR. The class was split into groups, and samples were collected from seven separate locations along the river and WWTP. There was also a sample collected by the S which is located between sites four and five. For each of these sites, there were ten groups from other labs that also collected a sample from the BSR. At site two of the river, the location included multiple sources of possible contamination. A drainage site was located 200 yards upstream, along with a small PVC drainage pipe next to the collection site. Not only was there drainage running into the river, the site was under a bridge, and contained other trash scattered throughout the area. The

Glow sticks, like many other everyday items, have chemistry involved with them. Glow sticks were discovered by Edwin Chandross in the 1960s. He was a young chemist at Bell Labs in Murray Hill, New Jersey. Edwin Chandross actually discovered the glow stick on accident. All along he was just trying to find a general way to explain chemiluminescence. By mixing florescent light and hydrogen peroxide with oxalyl chloride, he discovered how to create a glowing chemical light. From Chandross original discovery a lab team called American Cyanamid, led by Michael M. Rahurt, created an oxalate ester named phenyl oxalate to replace the oxalyl chloride. This lab team then sold their new product to a group named Omniglow who went

Everyone has done the volcano science project and I loved making bottles explode with a little baking soda and vinegar, but I wanted more. I spent (and still do) hours watching interesting science experiments ranging from the Pharaoh’s Serpent to precious metal refinery. However, most of the experiments were out of the reach of a young chemist at home. Instead, I looked around for chemical experiments going on around me.

The objective of this lab experiment is to measure the material in the gas phase and to see how the ideal gas experiment could apply to the physical. In this the material we used was, a sip-lock plastic bag, a large plastic beaker, thermometry, dry ice, water, and butane lighter.

i. The mixtures used in the IAA odor detection test shall be prepared in an area separate from where the test is performed, in order to prevent olfactory fatigue in the subject. j. If the test subject is unable to correctly identify the jar containing the odor test solution, the IAA qualitative fit test shall not be performed. k.

Together, my sister and I have conducted several backyard “experiments” that have usually ended in disaster. One time, we “discovered” that it’s next to impossible to clean tiny Styrofoam balls out of the grass, and another time we “invented” the world’s best slime that ended up staining the back patio a very unpleasant shade of purple. Our adventures and misadventures have allowed me to foster my curiosity and desire to discover new things.

You may ask what line spectrum is and why it is used by scientists or even how it is used in The Flame Test Lab. Scientists use the Flame Test and line spectrum to help them determine what an unknown element is. They can use the observation of the color and lines produced in a line spectrum by a gaseous state element to help them decide what the element is. Flame tests can be used to help the scientist determine what an element is in its solid form, by placing it in a flame and observing what color is produced. Wavelengths of color are emitted because of electrons becoming excited and jumping to higher sub-levels and then jumping back down to lower sub-levels.

Baking Soda and Vinegar - Drips out - This chemical reaction will be the slowest because it drips out like a slow waterfall.

The possibility of Muc5AC regulation by PPARγ at the level of gene expression might be an important event of PPARγ in epithelial cells along with its anti-inflammatory activities. To investigate the basis for Muc5AC repression by PPARγ, we analyzed the MUC5AC promoter for the presence of putative PPARγ transcription factor binding elements that may mediate this response. As shown in schematic representation, our analysis identified a novel PPARγ response elements (PPRE) between -3834 and -3821 bp (PPRE1: TGTTCAGAGGTCAA) and between -1207 and -1194 bp (PPRE2: AGGACAAAGGGCC) in the MUC5AC
