The Great Eastern Earthquake
by Aditya Ponugupaty
The Great Eastern earthquake and the tsunami that occurred on March 11, 2011 caused the meltdown of three nuclear reactors within several days, and four hydrogen explosions. Huge quantities of radioactive elements have been continuously released into the air and water. It will induce an epidemic of cancer, as people inhale the radioactive elements, eat radioactive vegetables, rice, and meat, and drink radioactive milk and teas.

Victoria Boller holding the limiting reactant demo.
Limiting Reactants determine how much product that can be produced in a given reaction. Students learn that they will experience limiting reactants as a manager of a company. Managers take risks purchasing items to be sold at a higher cost, thus the number of items on hand is called the limiting reactants. Steve holds a flask that has 10 cm of magnesium metal and 50 ml of hydrochloric acid. Victoria holds a flask with 3 cm of magnesium metal and 50 ml of HCl. The reaction produces hydrogen gas which fills the balloon. The size of the balloon is determined by the amount of limiting reactant present.
Stoichiometry concerns predicting a theoretical amount of product before the reaction occurs, so that when the actual value is produced in the experiment a percent yield can be calculated. Students learned that when managers of clothing stores like Von Maur order goods they have a theoretical dollar amount expected from the sale. However, changes in the weather or a bad economy can cause the store to discount and the actual money generated from the sale is compared to the theoretical in order to determine if the product should be ordered again. Students allowed the product to dry over night and will calculate the actual copper produced from the reaction to determine the percent yield.
One of the most impressive and significant features of the Periodic Table of Elements is the appearance of vertical groups of elements, which form "families". Elements that are in the same "family" or "group" form compounds that are similar in formula and physical properties.

The Hyman Fire Piston demonstrates the rise in temperature when a fixed mass of gas is compressed. A portion of tinder supported inside a transparent cylinder is ignited when the contained air is compressed by a hand operated piston.
Dakota Chappell uses the combined law apparatus to show that when the volume is decreased the pressure increases and the temperature increases.
The combined gas law is a gas law that combines Charles's law, Boyle's law, and Gay-Lussac's law. There is no official founder for this law; it is merely an amalgamation of the three previously discovered laws. The combined gas law can be used to explain the mechanics where pressure, temperature, and volume are affected. For example: air conditioners, refrigerators and the formation of clouds, and also use in fluid mechanics and thermodynamics.

Calorimetry is a technique that is used to determine the heat involved in a chemical reaction. When determining the heat of combusiton of a substance or the caloric value of foods, the measurements are often made using a bomb calorimeter. In this experiement the student used a simplified set up measuring the volume of water that melted from the ice in the metal container. The heat of fusion for water is 80 cal/g, so this value can be use to determine the energy content of food.

Slime
Elmer's Glue is made up of polyvinyl acetate, which reacts with water to some extent to replace some of
the acetate groups with OH (alcohol) groups. The B-OH groups on the borax molecules react with the
acetate groups on the glue molecules (relatively long polymer chains) to eliminate acetic acid and form new
bonds between the borax and two glue molecules. The linking of two glue molecules via one borax molecule
is called polymer cross-linking and it makes a bigger polymer molecule, which is now less liquid-like and
more solid.
Rachel Denny makes slime.
Jeremy Bonner examines his magnesium oxide ash. Christopher Cassetta Christopher Burton, and Zeb Fields measured out 0.5g Mg and cremated it in a crucible to obtain 0.75g MgO. The 0.5g Mg is mathematically calculated to produce 0.84g MgO. Thus the 0.75/0.84 g MgO x 100 produced an 89% yield.

Anion notes showing steps for testing four known ions for determination of an unknown.
Detectives in mystery novels often rush evidence from the crime scene to the lab for analysis. In this experiment, the student became the chemical detective. They conducted laboratory analysis to determine the ionic composition of an unknown anion solution. The four known anions were as follows: Chloride, Phosphate, Sulfate, and Carbonate. The teacher made the unknown solution to be Sulfate. The students performed the required tests and most got the identification of the unknown correct.
Steps for testing known cat ions for the determination of an unknown.
A cat ion is an ion that has a positive charge. It has a positive charge, because the atom has lost an electron and now the atom is not balanced or neutral. The electron is negative and the proton is positive. So when an electron leaves the atom the proton is the unit that provides the positive charge to the ion. Students use caution with Sulfuric Acid, Hydrochloric Acid, Sodium Hydroxide, and Potassium Chicano.

The Temperature-Pressure Law was studied by another French scientist. Joseph Gay-Lussac studied hot-air balloons in the early 1800’s. He studied the relationship between Temperature and Pressure. He found that when the temperature is increased, the Pressure of a gas also increased, and vice versa. He found the relationship was linear, but not quite direct. Similar to Charles’ Law, we must use The Kelvin temperature scale in order for the relationship to be direct. All we have to do is add 273 to our temperature celcius, and we get a direct relationship between volume and temperature.
Demi Gardner demonstrates the franklin apparatus.
Sophia Musa with the palm glass demonstrates the contrasting effects of heat and gravity on a volatile liquid.
The glass is filled with a colored liquid, such as methylene chloride, having a low vapor point. The air in the tube ahs been partially evacuated. The apparatus is held by hand at an angle, heat from the hand providing the input of energy.
A fluid with a low vapor point will evaporate with a relatively low input of thermal energy. The lowered pressure due to the evacuation of the tube enables the fluid to evaporate even more easily with the thermal input from the student’s hand.
Once the fluid reaches the upper bulb, it will cool and return to a liquid state. As it flows down to the hand-held bulb under the influence of gravity, it is reheated and evaporates again.
