Constructivism Critique of Minds-on Science and What’s the Matter I read Minds-on Science by Janet Raloff. I was surprised and delighted by Sherry Drillings way of teaching science. My first thought was that I can’t imagine a bunch of second grade girls being happy about playing with mealworms. At the same time I was such a tomboy growing up, I would have loved it. I really liked

DNA Many people disagree to the use of DNA results. Many question the accuracy of DNA evidence. DNA testing is very expensive, and the accused might not be able to afford a DNA expert to defend him/her in court if DNA evidence is used against them, and if DNA experts are hired for them, there is a possibility of bias. Under current law, only DNA from adults convicted of crimes can be pl

Fresh Fears Over Cell Phones Fresh Fears over Cell Phones Last summer a neurosurgeon in Sweden named Leif Slaford released data showing how drastically the brain is affected by cell phone exposure. Hundreds of studies in the last decade on cell phone exposure proved for the most part unsuccessful. Most only proving that cell phone use may be linked to headaches and slight memory l

Fruit Fly Experiment The common fruit fly, Drosophila melanogaster, used by Thomas Hunt Morgan in the early 1900’s to study genes and their relation to chromosomes, is a popular species used in genetic experiments due to its ability to lay down hundreds of eggs after just one mating, and their ability to mature in such rapid time, which is that of two weeks or less. The life cycle of t

Gene Therapy Reaction Paper The human body, with its trillions of cells, is the most complicated structure on this planet. All people carry a unique set of instructions that make up who they are within their bodies. These instructions are contained within our DNA and are the materials that our body uses to survive. Most of the time, our DNA allows for us to function without any major men

Drosophila Melanogaster Drosophila melanogaster Introduction Drosophila melanogaster, the common fruit fly, has been used in studying genetics since the early 1900s, when Thomas Morgan began using them in genetic studies. Drosophila melanogaster is so commonly used for studying genetics for many reasons. One advantage of using the fruit fly is because its genome is rather small. Als

Diabates Diabetes With all the threats of harmful health, some diseases can be prevented with just a healthy lifestyle of eating correctly, exercising, and maintaining a stress-free mindset. But these techniques for a successful healthy body can only be minimally helpful in the world of diabetes. With diseases such as diabetes mellitus, that can passed on genetically, a person can’t esc

Endocarditits Endocarditits was the predominant bacteria found in both case studies. While both were gram negative, each stemmed from a different Genus. In article A, we studied a case of Haemophilus aphrophilus endocarditis, found in a patient with his tongue pierced. Colonization of the bacteria was found around the stud (jewelry used for piercing). In article B, the Q fever endoca

Diabetes Diabetes, a life long disease for which there is not yet a cure, is caused by reduced production of insulin, or by decreased ability to use insulin. Insulin, the hormone produced by the beta cells in the pancreas, allows blood sugar (glucose) cells to be able to use blood sugar. This hormone is necessary for glucose to go from the blood to the inside of the body cells. With i

Environmental Subduction creates volcanos when one tectonic plate is pushed down by another. Transverse movement is when the tectonic plates apply so much pressure that they slip sideways/earthquake. Ecosystem is all living things and nonliving things in an area. Lithosphere is part of the earth beneath ou feet, solid. Hydrosphere is all of the water on the earth. Atomosphere is the gas/

Hydrogen Hydrogen Hydrogen is defined in the 1984 edition of the World Book Encyclopedia as “a tasteless, odorless, colorless gas, and on of the most important elements”. Henry Cavendish, of London, England, found this to be true in 1766 when he discovered the ninth most abundant element in the earth’s crust, Hydrogen. Although scientists believe that hydrogen came into being withi

Enzymes Lab Problem The phenomenon that we were looking at was how enzymes in potatoes react with substrate. The enzyme will react with the substrate and use the substrate up but the enzyme will regenerate until the substrate is used up. The reaction for this can be written as: E+S ES E+P Where E is the enzyme, S is the substrate, ES is a stage called enzyme-substrate, and P

Human Cloning Human Cloning After hundreds of failures including several badly deformed creatures in 1997, Ian Wilmut, an embryologist, cloned a sheep name Dolly at Roslin Institute in Edinburgh, Scotland (Leone 49). The news of Dolly shocked the world and scientists all over the world begin to debate about if it is right to clone a human. According to Longman Advanced American Dictio

Chemical Formulas Chemical Formulas Objective The object of this lab was to help show how chemical formulas explain the displacement of chlorine in the reaction. Also, the purpose was to find and understand empirical formulas, and how to find the empirical formula for ZnCl2. Procedure First, obtain the necessary materials and set them up on a clean bench.

Neurofibromatosis Neurofibromatosis is a disorder affecting the chromosomes of the human body. It is a hereditary disorder affecting the nervous system. The term neurofibromatosis actually refers to two different genetic diseases. The most common type is NF 1, and the less common type is NF 2. Both disorders are transmitted in an autosomal dominant fashion. An autosomal dominant disease

Physical Science Objective The goal of this experiment is to develop a theory, which allows us to understand the motion of a marble. Materials Wooden roller coaster, marble, ruler, timer, clamp, physics stand. Theory In this experiment, we are finding the Conservation of Energy. Energy is neither created nor destroyed. Energy is summed up into two different propert

Polarity Of Water Water has a simple molecular structure. It is composed of one oxygen atom and two hydrogen atoms. Each hydrogen atom is covalently bonded to the oxygen via a shared pair of electrons. Oxygen also has two unshared pairs of electrons. Thus there are 4 pairs of electrons surrounding the oxygen atom, two pairs involved in covalent bonds with hydrogen, and two unshared pairs

Digestive System Digestive System The digestive system is the the group of organs that changes food to carbohydrates, fats, and proteins and used by our body. Digestion takes places begins form our mouth and ends with our anus. the function of our digestion system are to ingest food, digest into nutrients, cross our plasma mambranes, absorb nutrients and eliminate indigestible r

Digital Cameras Digital Cameras Digital cameras allow computer users to take pictures and store the photographed images digitally instead of on traditional film. With some digital cameras, a user downloads the stored pictures from the digital camera to a computer using special software included with the camera. With others, the camera stores the pictures directly on a floppy disk or on

Hurricanes What is a hurricane' Hurricanes are tropical cyclones with winds that exceed 64 knots (74 mi/hr) and circulate counter-clockwise about their centers in the Northern Hemisphere (clockwise in the southern hemisphere). They are formed from simple complexes of thunderstorms. Hurricanes only form from these thunderstorms with the cooperation from both the ocean and the atmosphere

Musuem Of Natural History The American Museum of Natural History was visually a lot more interesting than the other museum I visited. The exhibits were extremely very nicely detailed, from everything to the actual models themselves to the sounds playing in the background in the volcanoes exhibit and in the oceans exhibit. These were the two exhibits that fascinated me the most of all of

Marshes are usually protected from waves by natural sources, which helps create breeding place for species absolutely necessary for the prosperity of our food chain. Marshes can also be found by fresh water th

Protiens Laboratory Report Section 3.1-Test for Proteins A protein is a long chain of amino acids that are linked from end to end by peptide bonds. The function and shape of the protein are determined by the sequence of its twenty amino acids. Proteins perform different functions in a cell. For example, regulatory proteins regulate, or control, cellular metabolism. Hemoglobin carr

Stem Cell Research And Funding Since the discovery of the utilization of stem cells to possibly cure millions of debilitating diseases, the controversy has focused on how ethical the practice is. But for the majority the controversy lies in the funding of the research. Federal funds are available for stem cell research but the government has put stipulations on that research leaving the

Small Pox Small Pox Remember having the Chicken Pox when we were little' If you never had Chicken Pox, it consists of having several small bumps that cover the entire body over and over, they itch, some would hurt, and all you would hope for would be for them to go away. Chicken Pox would last an average healthy person a few days. With Small Pox a person can run a high fever for

Southstreet Seaport Museum The South Street Seaport Museum turned out to be a lot more interesting than originally anticipated. At first I went to the gallery on the left when your first enter the seaport (not the one where the gift shop is located). I spoke to the old lady, which is respectable, for elderly people have more experience in life. Anyway, she seemed extremely knowledgeable

Sudden Infant Death Syndrome When a parent loses a child, the thought alone is indescribable. The death leaves a permanent hole in the heart of the family. To have a child die of Sudden Infant Death Syndrome (also known as S.I.D.S.) is sometimes actually defined as indescribable – words can never be enough to explain away the pain. SIDS is the sudden death of an infant under one year

DNA Hybridization In 1960, Julius Marmur and his coworkers conducted studies at Harvard University that resulted in the discovery of the process of reannealing. This process involves the reassociation of single strands into double-stranded molecules that are stable. From the discovery of the reannealing process, the methodology nucleic acid hybridization has evolved. Using this t

Federal Funding Of Death Federal funding of embryonic stem cell research has been a debatable issue since the 2004 Presidential election. Embryonic stem cell research involves removing stem cells from human embryos resulting in their destruction. These stem cells can form “stem-cell lines” that have the potential to be produced into 210 different kinds of tissue that can help restore los
