referred to as transitions. A child is expected to cope with changes such as movement from nursery education to primary school and then on from primary school to secondary school etc. How a child copes with change will vary enormously from child to child and will depend on such factors as the child’s age‚ understanding and how they have been prepared for the change. Some children may

As the temperature increased‚ the enzyme activity also increased‚ however‚ only to an optimal level which was at temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

human reaction time for a simple task. Hypothesis If the activity is repeated a number of times‚ then the reaction time will decrease‚ therefore the slower the reaction time‚ the further the ruler will fall. Variables - which variables are you going to: Change? (Independent Variable) The Independent Variable in this Investigation is the reaction time. Measure? (Dependent variable) The Dependent Variable in this Investigation is how far the ruler falls. Keep the same? (Controlled variables)

‘Kinetics’ is the study of chemical reactions. The speed of a reaction can vary depending on many variables such as the nature of the reactants‚ particle size‚ concentration and temperature. For a chemical reaction to occur‚ there must be a collision between reactants. The reaction rate is slower when the reactants are large and complex molecules because it takes longer for the molecules to combine together creating a chemical reaction. More than 2000 years ago‚ Democritus‚ who was a philosopher

students to learn there are several factors that must be considered. Most of these factors are external; they deal with social or cultural values. Also‚ it may be determined by the school’s environment as well as the teachers and administrators that teach them. Still‚ another important factor falls upon the student’s ability and willingness to learn. Here are several factors that can affect the way a student learns during these formidable years. SOCIO-ECONOMIC FACTORS Students come from various backgrounds

Factors Affect Communication Process FACTORS THAT INFLUENCE THE COMMUNICATION PROCESS Perception Perception is a process by which the meanings of messages are interpreted. The way messages are perceived is related to a combination of a person’s social and cultural influences‚ gender‚ educational background and knowledge‚ and past experiences (Schuster 2010). This complex mix of influences means that no two people are likely to perceive the same message in exactly the same way. Some of the strongest

2a. What abiotic factors might account for any differences between different types of habitats‚ such as disturbed and less disturbed hillsides? Explain. Abiotic factors are non-living chemical and physical parts of the environment that affect ecosystems. These include temperature‚ light (sun exposure)‚ soil composition‚ rocks‚ water‚ air pollution‚ humidity‚ radiation‚ and wind that can influence a species’ ability to survive. In each case the impact on the ecosystem will depend on the intensity

have to face very particular and personal transitions not necessarily shared or understood by all their peers. These include: family illness or the death of a close relative; divorce and family break-up; issues related to sexuality; adoption; the process of asylum; disability; parental mental health; and the consequences of crime. It is important to understand a child or young person in the context of their life‚ to recognise and understand the impact of any transitions they may be going through.

How does a Lens Refract Light? Different Lenses refract light in different ways. First‚ we will look at a double convex lens. Several light rays will approach the convex lens in a parallel manner. After they approach the lens‚ each ray will refract towards the normal. The light is passing from an optical less dense medium (Air) into a more dense medium (such as plastic or glass) at this boundary. Since the light rays are passing the boundary from a less dense medium in which light travels fast (optically
