Unit 1 This scheme of work suggests possible teaching and learning activities for each section of the specification. There are far more activities suggested than it would be possible to teach. It is intended that teachers should select activities appropriate to their candidates and the curriculum time available. The first two columns summarise the specification references‚ whilst the Learning Outcomes indicate what most candidates should be able to achieve after the work is completed. The Resources

Thermodynamics Section Review 9A: 1. Scientists believed that the caloric was a material but mainly that it was an invisible fluid consisting of self-repelling particles. Two examples include how gases expand according to Newton’s laws‚ and determining the speed of sound in air. 2. The first person to successfully challenge the caloric theory was Benjamin Thompson. Benjamin observed that a dull boring bit could generate more hat than needed to melt the entire cannon barrel. 3. The significance

equations of electromagnetism and Hertz experiments on the generation and detection of electromagnetic waves in 1887 strongly established the wave nature of light. Towards the same period at the end of 19th century‚ experimental investigations on conduction of electricity (electric discharge) through gases at low pressure in a discharge tube led to many historic discoveries. The discovery of X-rays by Roentgen in 1895‚ and of electron by J. J. Thomson in 1897‚ were important milestones in the understanding

Essay ON PAcemaker A pacemaker (or artificial pacemaker‚ is a medical device that uses electrical impulses‚ delivered by electrodes contacting the heart muscles‚ to regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequateheart rate‚ either because the heart’s native pacemaker is not fast enough‚ or there is a block in the heart’s electrical conduction system. Modern pacemakers are externally programmable and allow the cardiologist to select the optimum pacing

these attempts have been merely limited to cold hydrogen plasma treatment5 in which the hydrogen plasma bombardment also creates numerous undesired defects in the graphene structure. Since graphene conduction proves to be very challenging. To date‚ the chemical hydrogenation graphene to modulate its conduction has never been reported. In this communication‚ we report a novel and facile method to hydrogenate graphene by using bulk amounts of catalyst placed upstream of the graphene flake films in the

The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries (which provide oxygen and nutrients to body tissues by transporting the blood throughout the body). The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum. On its superior end‚ the base of the heart is attached to the

Neuro notes for test 2! Cell membranes are composed of a lipid bilayer. It has different receptors that allow different ions to pass‚ depending on the conditions in the cell. Leak channels- always open allow ions to flow back and fourth across the cell membrane Na cl ‚K and Ca ions and they just flow back and fourth without any gate keeper or obstruction‚ When the neuron is at rest its cytoplasm is Negatively charged. That means that it is not going under depolarization‚ we use the term resting
