the term given to the movement of air in and out of the lungs; the rate of pulmonary ventilation is defined as the tidal volume multiplied by the number of breaths taken per minute. Tidal volume is the volume of air breathed in or out during one cycle of quiet breathing. There are a few different factors that can affect the pulmonary ventilation rate but the most common and often most noticeable variation in pulmonary variation rate occurs during exercise. During normal quiet respiration‚ the average

the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into a series of colours. This shows that white light is actually made up of many other colours - a fact first

pressure in the maggots’ chamber decreases‚ causing air to be drawn into the chamber‚ and therefore displacing the fluid. This double chambered respirometer‚ allows you to measure the pressure changes‚ due to the presence of a control tube. The rate of oxygen intake is measured by recording the distance the dye moves up the scale. We then calculate the mean and multiply by ?r².

Experiment to investigate the lateral displacement of a ray of light through a rectangular block of a transparent material. Aim: - To investigate the lateral displacement for different angles and how the displacement depends on the angle of incidence when a ray of light enters the Perspex block. Scientific Background: - Refraction occurs when the speed changes when the lights travels from one medium to another medium. If the light travels from a medium to a denser medium‚ the light slows down and
