Logan Brink Kemper p.6 Chemistry January 11, 2014 Grams Ahoy! Purpose: The purpose of this lab is to find the weight (in grams) of the chocolate in a chocolate chip cookie. Hypothesis: If the chocolate is separated from the cookie, then the chocolate will weigh 40% of the weight of the whole cookie. Materials: * 1 chocolate chip cookie * 2 plastic trays * 1 pair of tweezers * 1 gram scale Procedures: I. Weigh chocolate chip cookie on the gram scale and record. II

AP Physics – Waves Ain’t Gone, Alas - 4 Thee Hee?________________________________________________________________________Per__ School days, I believe, are the unhappiest in the whole span of human existence. They are full of dull, unintelligible tasks, new and unpleasant ordinances, brutal violations of common sense and common decency. -- H.L. Mencken 1. A 7.50 kg ball is thrown. It has an initial velocity of 8.468 m/s. It travels a horizontal distance of 7.3 m in 1.25 s. Find: (a) The weight

Introduction In this decade, the environmental status of earth is frequently debated. The impacts of human activities cause major environmental problems such as greenhouse gases and global warming. Therefore it is essential to find out which of them has major effects on environment. The depletion of natural resources, or other environmental issues demonstrate that there is not enough awareness concerning to consequences of human activity. That is why the term of sustainability was

3. What key concepts or “constructs” are used to explain your personality? The key concept I chose to explain my personality would have to independence. I was raised by a single mother with hardly any family. She taught me that I was responsible for my actions, nothing would be handed to me, and that I had to work for what I wanted. I learned early on through my independence to appreciate all that I receive and all that I earn. That is why I believe I chose persistence and hardworking

Prioritizing for Responsible Productivity Growing up, responsibility was something most young minds feared. The way parents spoke of responsibility, portraying so much struggle and frustration, it was evident most individuals dreaded growing up and acquiring more responsibility than simple chores around the house. That was then. When one experiences what comes with age, things become easier to accept. Through the years one can learn to distinguish the difference between selfishness and independence

The Efficiency of a Ramp By: Tony Akiki Partner: Nikolas Dobson Teacher: Mr. Devine Class: SPH3U1 School: Saint Johns Collage Date Concluded: June 10, 2016 Due Date: June 17, 2016 Question: How does the angle of inclination on a ramp affect the efficiency of the ramp? Hypothesis: I believe that the steeper the ramp is the more work you have to put in to push it up making to less efficient. If the angle of the ramp is very low, then you will have to put less force into it. This makes

Introduction A rotocopter is a smaller simpler version of a helicopter. The rotocopter displays two simple blades that are re shaped into a rectangle a circle and a triangle as the experiment is conducted. These results allow us to determine how the blade shape affects a rotocopter’s flight time. Although the helicopter looks to be complex and maculate the helicopter and the rotocopter have many similarities. Such as each depending on rotors and how the rotors are designed. The aircraft in

object to undergo a certain change, either concerning its movement, direction, or geometrical construction. It is measured with the SI unit of newtons and represented by the symbol F. In other words, a force is that which can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or which can cause a flexible object to deform. Force can also be described by intuitive concepts such as a push or pull. A force has both magnitude
