Science Fair Demo

The Mythbusters observed the myth that driving whilst talking on the phone is as dangerous as driving drunk. They formed their hypothesis that driving on the phone is as dangerous as driving drunk. Then, they tested their hypothesis. They created an experiment that would have participants drive a car through a course three times. Each time a participant went through the course, they experience different conditions. The first time, both participants drove through the course normally. This served as the control group for the experiment. The second time, participants were asked questions over the phone while they completed the course, and, the third time, they were drunk when they drove through the course. Throughout the experiment, there were several independent variables in place to ensure that only one variable was being tested.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

The history of fires goes back to the 17th century. They were called, “Fire buckets”. They came into existence because there was no fireman. Fire buckets were people organizing themselves like a human chain with buckets passing around. There was at least two to three buckets full of

The flamethrower has been around for a very long time, as far back as the 5th century b.c. Now recently in the last 100 years made a reappearance and this time it is even more deadly than before. The reoccurrence of popularity came about in around 1915 when a German scientist named Richard Fiedler came up with the first modern flamethrower. The flamethrower is a weapon that if you couldn’t tell by reading the name, it shoots out flames. How a flamethrower actually works is not as hard as it sounds “These took the form of lengthy tubes filled with burning solids (such as coal or sulphur), and which were used in the same way as blow-guns: by blowing into one end of the tube the solid material inside would be propelled towards the operator's enemies.”http://www.firstworldwar.com/weaponry/flamethrowers.htm

When analyzing the IR spectrum of Ruthenium complex with DMSO, the prominent peak is presented at 1105.54 cm−1. This peak indicates that S=O bonded in DMSO. For DMSO, the frequency is around 1050 cm−1. From our spectra obtained for DMSO where the S=O peak is at 1017.65 cm−1. Since the bond appears at a higher frequency, this shows that the bond is strengthened by the reaction. This indicates that when the copper metal was combined with DMSO, it bonded with the Sulfur atom. Combining ruthenium with sulfur atom caused it to donate a pi electron as a back donation.

-The more dissolved oxygen in the water, the more fish is observed in that area of water.

It is estimated that our ancestors first discovered and used fire up to 1.6 million years ago. Early humans used fire to help them survive. They used fire to cook food and keep themselves warm. As humans evolved, so did their uses for fire. Starting with the Greeks and Romans, humans used fire not just to help themselves, but to hurt others. In warfare they would use fire to inflict pain and suffering on their enemies. Using fire in this way was continued for thousands of years during wars. Fire was used greatly during the holocaust to inflict physical and mental pain on people in concentration camps . In the novel Night, Elie Wiesel tells his story of his life during the holocaust. We follow Elie as gets forced out of his home into a ghetto,

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

according to the novel fahrenheit 451 firemen did put out fires way back in times before society changed. In guy montag's society, firemen start the fires in the homes of the people who are suspected of hoarding books and other materials that goes against the grain of their uniform and conformities of society. They must start the fires but not harm anyone and make sure that all the books and reading materials that are against the law are burned or

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.

Did you know that the earliest form of firefighting took place in Rome in 24 B.C? After almost being destroyed by unruly conflagrations, Rome created a fire department consisting of about 7,000 paid firefighters. Their fire crews responded to and fought fires, and also patrolled the streets with the authority to fine anyone who disobeyed the fire prevention codes (Hashgan). The major piece of firefighting equipment the Roman's used was the bucket, which was passed from hand to hand to deliver water to the fire. Additionally, they used an ax, which was utilized to remove the fuel and prevent the spread of fire, as well as to make openings that would allow heat and smoke to escape a burning building.

Procedure: We held our plastic over the flame and observed the way our plastic burned.

whip up the egg whites in the kenwood until they were foamy and then slowly add the sugar in, tablespoonful at a time until I had about half of the sugar left and then pour the remainder of it in slowly, and then leave it in the kenwood until it was a thick mixture with stiff peaks. I decided that sticks of meringue would go best for the sensory analysis as they are easy to eat and were more practical than a nest for a sample. Why do the eggs need whipped when making meringue? When the egg whites are whipped, the protein molecules unfold from their natural shape and tangle together, also, the air is trapped into the egg white during the time that it is getting beaten. The protein molecules become attached to each other through chemical and

The overall purpose of the lab is to have the students practice designing an experiment, gathering data, and then analyzing that data to form a conclusion using the scientific method. It also served to understand key terms such as hypothesis, dependent variable, and independent variable. The specific objective of this lab is to determine whether certain human body parts experience allometric or isometric growth. Allometric growth defines when certain parts of an organism grow at unequal rates in comparison to its whole, while isometric growth is when all parts of an organism grow at the same rate in comparison to the entire organism. The specific purpose of the lab is to determine whether or not specific human body parts experience allometric or isometric growth by comparing the ratios of height to two specific body parts, in the students’ case the right hand length and head circumference, in students and newborns. The students formulated the tentative answer that if a team of four compared their height to right hand length ratio, as well as, their height to head circumference ratio, to those of a newborn’s, then the students will discover that the right hand and head experience allometric growth in humans.

Over time, the perceived meaning of words varies greatly. This can lead to some corruption of the original meaning in the minds of people. Fire was originally created by humans to cook food, which partially digested the food for people and so allowed people to have smaller stomachs and thus have larger brains. Fire was also used as a light source when night came, creating a “safety net” of light around camps. After its invention as a cooking tool and a light source, fire began to be used as a weapon. By dipping sticks into fire, people could create torches, with which they could ward off predators. These original uses of fire helped to expand humanity, thus contributing to the creation of civilization. Without fire, civilization as we know it may not exist.
