Liam Stephenson controlled assessment Introduction In my course work I will be looking at how the thickness of a converging lens affects the focal length. The factors involved in this experiment are: light, lens curvature, refraction and thickness of the lens, these will determine the focal length; the focal length is the length between the focus and the lens. Light-visible light is an electromagnetic wave in the electromagnetic spectrum The speed of light depending on the medium it is in, for example the speed of light is 300,000 km/s however when light travels through other medium such as water or glass the speed of light is slowed this is because water and glass is denser than a vacuum of air. Due to it being more dense and a change in speed, the direction of the wave will change this is
As the solvent moves up the paper, it carries along any substances dissolved in it, which are the pigments. The heavier the pigments the slower they move and they do not travel as far. Going in order from the heaviest to the lightest: Chlorophyll b, Chlorophyll a, Xanthophylls, and Carotene, which means that the lighter the pigment the better the substance is in dissolving in solvents. Photosynthesis
the service users we care for are often particulary vulnerable to infection, and as such we need to be extra careful, clothes can pick up infection and pass it from one service user to another. It is important that you change your
Just because it is clean doesn’t mean that it is ready to run. Once you have cleaned everything it is time to take things apart by separating the two ends from the chassis. This will let you inspect the suspension and bulk heads more easily. You are mainly checking the shocks for pressure and the wheels and axial for binding and fluidity. It is important to make sure all the screws are tight, especially along the axil.
Calonna Taylor Professor Osborne BSC2010C 9 February 2014 Beyond The Cells Purpose: The purpose of this lab report is to become familiar with the use of a compound microscope and the Gram Stain. Hypothesis: If you do not know how to use a Microscope or how to Gram Stain, then your results of your lab will come out inconclusive or just wrong. Part A: Cell Structures Materials & Methods: Materials: * Colored Pencils * Paper * Access to a scanner Methods: 1. View video “Using a Microscope.” 2. Look at the slides and identify the cell structure within.
Alyscia F. Monaco Unit 9 Assignment 2 05/15/2015 The Aging Special Senses Glaucoma is a condition that causes damage to the eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye. Glaucoma tends to be inherited and may not show up until later in life. The increased pressure, called intraocular pressure, can damage the optic nerve, which transmits images to the brain. If damage to the optic nerve from high eye pressure continues, glaucoma will cause permanent loss of vision.
The thick glass is more likely to crack since glass is a poor conductor of heat. In a thin glass, the heat passes more quickly from the glass into the surrounding air, causing the glass to expand equally. When hot water is poured into a thick glass, the inner surface expands, but the outer surface does not. It is this extreme stress on the glass that causes it to crack 20.

If the body temperature falls just 3 degrees, you can experience hypothermia which can cause death, stroke, and cardiac arrest. Ultimately suffering brain damage if the temperatures are too high, metabolic reactions become slower because molecules move slower and have less kinetic energy. If core temperature rises above, the enzymes of the body start to become denatured and metabolic reactions will be slow. Changes are due to the ‘fight or flight response’ of the sympathetic nervous system caused by the release of hormones which are released called adrenaline and noradrenaline, The raised heart rate allows the heart to achieve a bigger cardiac output, supplying the working muscles with the necessary amount of oxygen for them to function properly because CO2 is needs to be excreted. It controls the redistribution of blood from the abdominal tract to the working muscles to meet oxygen demands.
Facilities should set the guidelines for punishment and make it known across the entire facility, but if a supervisor recognizes the violation, they should handle the punishment, and making human resources aware of a possible violation. Regulations for investigation of possible privacy violations should also be handled by human resources and administration. Overall review of privacy policies, HIPAA regulations, and private regulations should be in serviced frequently to ensure comprehension to the fullest and the repercussions that would
Whilst I was at placement I have taken part in a lot of activities. Some of these have needed me to tell the children how to work safely. One of the activities that I had to do this was when they were using the scissors. I assisted in an activity where they had to make puppets. This was done by using some felt and cutting it to a shape of a charicter they wanted to make out of a book i drew the shape on the felt and asked the children to cut around it.
