“The Domino Effect” Teacher’s Prompt Investigate the domino effect with a set of dominoes. Aim To investigate the relationship between the mass of the dominoes‚ and how it impacts the time taken of the domino effect. Independent Variable: The mass of each domino (12.38 g‚ 32.38 g‚ 42.38 g‚ 62.38 g‚ 82.38 g). Dependent Variable: Time taken of the domino effect. Controlled Variable: The number of dominoes used (8 dominoes)‚ the distance between the dominoes (2 cm)‚ the loads used as the initial

Introduction: Purpose: The Purpose of this experiment is to find the width of a piece of hair using diffraction pattern created by a thin film. Hypothesis: If the hair is human it will have a width of 10-4m. Procedure: 1. Place two pieces of glass flat against each other. 2. Obtain a piece of long hair‚ most likely from one group member’s head. 3. Place the hair between the sheets of glass on one edge. 4. Place a rubber band around the pieces of glass on the side opposite

6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing

LAB WRITE-UP NAME: Gabriel-Ohanu Emmanuel PARTNER: Baptiste Gilman TITLE: Graph Matching PURPOSE: The purpose of the experiment was to analyze the motion of a student walking along a straight line in front of the motion detector moving back and forward with different speed trying to match the graph provided. To also understand and interpret graphs of distance vs time and velocity vs time. To also know what the slopes of the each graph represent which tells how far the student travelled

HG-1 THE HEAT OF FUSION OF ICE Introduction When heat flows into a system there are a number of things that can happen. One result could be a temperature rise. Or‚ the system might even catch fire. A third possibility is a change of state. As you know‚ matter exists in three states (or maybe four‚ the fourth being a plasma)‚ solid‚ liquid and gaseous. At different temperatures‚ the same substance may be in different states. Each state is characterized by the way the interatomic forces act. In solids

Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration
