Since there are many different definitions of handedness‚ the results of my experiment could be significantly affected by my choice. For the definition that I will use in this case‚ handedness is the hand that one prefers and performs better in use. Because the two most common definitions were the hand that one prefers‚ or the hand that one prefers to use‚ I made my own definition of combining together. In this experiment‚ handedness has to match both of the conditions of preference and performance

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in

In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences

Student: (Be sure to look over all your notes and be sure to know the following things) 1. Define Temperature‚ thermal energy and heat. 2. A 1.00 x 10²g mass of tungsten at 100°C is placed in 2.00 x 10²g of water at 20.0°C. The mixture reaches equilibrium at 21.6°C. Calculate the specific heat of tungsten. Cw = 4180 J/kg°C C= 171 J/kgOC 3. A certain metal has a specific heat of 400 J / kg oC. It absorbs 8000 J of thermal energy which causes its temperature to raise 10oC. How much

THE EFFECT OF CHANGE IN pH ON THE ACTIVITY OF ENZYMES Introduction: Enzymes are catalysts that speed up‚ and control chemical reactions within a cell and break down complex molecules into smaller ones. Some of the chemical reactions that take place in the body produce toxic by-products which need to be converted. The liver produces hydrogen peroxide‚ which is extremely poisonous. When the catalase comes in contact with the hydrogen peroxide‚ it is broken down into water and oxygen. Aim:

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this
