Physics 1 Lab #10 1/29/13 Chapter 7 Lab:Pop Rockets 1. List and explain two ways that you could improve the flight performance of your rocket. Your responses must consider the materials you had available to work with. The rocket I produced was a normal looking rocket compared to the group of rockets I was working with. It was medium size in length and thickness. The head of the rocket was a little wide and lose‚ and the flaps were not arrow dynamic what so ever. To improve the flight

Waste Water Treatment Samuel Rodriguez May 29th‚ 2013 Abstract: In this lab‚ we were introduced into the steps that the San Diego Water Treatment plant does to clean and filter that water that goes into millions of homes in San Diego. The purpose of this lab was to correctly follow the safety procedures that the San Diego Public Utilities Water and Wastewater plant have to follow so that we can raise our awareness of our own backyard‚ our own streets‚ our own oceans‚ and our own world

In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide

What Amount of Water Grows the Plant the Longest? Daniel Rivera Alfonso Pineda Mrs. Fraijo AP Biology 10 June 2012 Abstract: In this experiment‚ 8 plants will be tested. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. Each plant will receive 1 more teaspoon than the previous cup‚ so it would be increasing. For example‚ cup 4 will have 4 teaspoons of water and cup 3 would have 3. The data recorded will be

Seperatation Technqiues of Sand/Salt/Water Mixture Most of the material that are encountered in everyday life are not pure substances. Materials ranging from cement‚ food and ink are formed from physical combinations of various substances called mixtures. A mixture is a type of material that consists of two or more different substances that are not chemically combined. All mixtures can be separated back into its original state except for those that undergo irreversible change. A mixture can take
