Popcorn Experiment Experiment performed on 8/26/11 Biology 101 Introduction: “The oldest popcorn ever found was discovered in the “Bat Cave” of central New Mexico. Archaeologists found 80‚000-year-old corn pollen below Mexico City”. “The popcorn was thougt to be about 5‚600 years old”. (www.factmonster.com/spot/popcorn1.html) This particular pollen is almost identical to today’s popcorn pollen. Researchers came up with the theory that popcorn could have been a Stone Age snack for “cave

coarse aggregate mix‚ given the bulk density and minimum void content. Equipment * Electronic Balance * Metal Cylinder (AS Compliant) * Metal Scoop * Tamping Steel Rod Test Procedure 1. Determine the weight and volume of the cylinder (for lab experiment written on side). 2. For the mixed aggregates ensure they are well mixed. Now fill the cylinder with the aggregate to 1/3 the height of the cylinder using the scoop. 3. Compact the aggregate with the tamping rod giving 25

Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical

2013 Hexagon Area Hello Timmy! I heard you have been sick with the flu for a while so‚ I took the liberty of getting you on your feet before class so you are not lost. So this paper will help you find the area of a hexagon using special right triangles‚ using trigonometry‚ breaking the hexagon into smaller polygons‚ and even show you how to construct one! So let’s get started‚ this hexagon has a radius of 6 cm‚ keep in mind that there are many different ways to do find the area of a hexagon. Use

between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be repeated for better precision. The following

of viral genome-->late gene expression->assembly of viral progeny-->exit 2. Concept 2.1- Virus entry is a multistep process with the ultimate goal of delivering viral genome (payload) into the cells. A. Binding to surface receptors- - a viral receptor is cell surface molecule‚ likely a transmembrane protein - a virus may need multiple receptors to enter the cell -the ability of viruses to infect certain cells but not others are typically due to the fact that only the "permissive cells"

Advertisment Essay The advertisement I chose was an advertisement for the new Microsoft(TM) tablet called Surface. It is a commercial that gets its point across quickly‚ clocking in at exactly one minute and 37 seconds. The ad is quite effective in pulling the viewer in‚ with its ever-changing imagery. Being quick but full of information is a working formula that does a lot of good to help sell the product. Comes in‚ tells you what the product is all about‚ and leaves. This allows the information

Mole Ratio of a Chemical Reaction: Copper & Silver Nitrate Lab #4 OBJECTIVE In this experiment‚ you will determine the number of moles of reactants and products present in the reaction of copper and silver nitrate‚ and calculate their mole-to-mole ratio. The mole-to-mole ratio relating to the disappearance of copper and the formation of silver metal will be used to write the balanced equation for the reaction. The reaction of copper metal with silver nitrate solution is a single

Biology College of Science De La Salle University – Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by
