Abstract This lab’s purpose was to test the patterns of percolation in various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction

Vinegar Girl by Anne Tyler is a 2016 retelling of William Shakespeare’s Taming of the Shrew. The book was published as part of the “Hogarth Shakespeare” project by Random House. Tyler’s protagonist‚ Kate Battista‚ is just as strong-willed as Shakespeare’s Katherina. Likewise‚ both protagonists are prickly with those around them. Tyler opens Vinegar Girl with Kate in her garden her father‚ Dr. Battista‚ calls her on the phone. He forgot his lunch and would like her to bring it to him. Kate agrees

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side

Science Assignment 1.1 Introduction Vinegar was discovered around 5000 BC and it is documented to have been used by Hippocrates who has used vinegar as a medicine for wounds. Vinegar has many uses‚ although the main use for vinegar has been for treatment of wounds. It is also been commonly used as a cleaning agent throughout the years‚ even to this day. Vinegar is often used in cooking‚ especially salads. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1785201/ Neutralisation (in science) is to

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test
