Unit 331 5.1&5.2 Explain the different types of transitions can affect children’s development and evaluate the effectiveness of positive relationships during periods of transitions. Transitions are the movement or changes from one position‚ stage or state to another. These changes can be gradual or sudden‚ and last for differing periods of time. Transitions can be stressful for young people and this stress can have far reaching effects on children’s emotional wellbeing and academic

Discuss how different approaches to learning can affect student success in higher education Introduction: Approaches to learning are defined as “the ways in which students go about their academic tasks‚ thereby affecting the nature of the learning outcome” (Biggs‚ 1994 cited in Chin‚ 2000‚ p.110). However‚ the idea of classifying student’s approaches to learning began since Marton and Saljo’s research in 1979 (Ramsden‚ 2003). The research attempted to find an appropriate answer for the various

Does Soap Affect the Surface Tension of Water? Background: Surface tension refers to water’s ability to "stick to itself". Surface tensioncan be measured and observed by dropping water (drop by drop) onto a penny. Thenumber of water drops that can fit on a penny will surprise you. Question: How does soap affect the water’s surface tension? Hypothesis: I think that the surface tension of soapy water will be less than that of freshwater because H 2 0 has strong polar bonds‚ and when water is mixed

How can nutrition and recovery strategies affect performance? 54. Why is a well balance training diet essential for an athlete? A well balance training diet is essential for an athlete. Good diet and nutrition can enhance sporting performance. Carbohydrates should form the basis of the sportsperson’s diet. For most athletes‚ a varied healthy diet will provide vitamins and minerals‚ as well as protein‚ to promote growth and repair of muscle tissues. Adequate fluid intake is essential to help performance

How does surface area affect reaction speed? The aim of this experiment was to investigate how the surface area affects the rate of a reaction in between calcium carbonate and hydrochloric acid. My hypothesis was that if the surface area to volume ratio of calcium carbonate was increased‚ then the rate of the reaction will increase because there are more particles that are accessible by the hydrochloric acid‚ thus more particles that can react with each other. Variables Independent- Surface

Describe‚ giving examples‚ how different aspects of development can affect one another. There are many examples that show how different aspects of development can impact one another. In majority of cases‚ one aspect will lead to another as a natural result‚ so for example‚ if a child has a speaks foreign language as his/her first and family just came to UK to live‚ this may lead to having language barrier‚ he/she may become shy‚ not very communicative‚ isolated‚ which affects emotional and intellectual

Describe‚ giving examples‚ how different aspects of development can affect one another There are many examples that can describe how different aspects of development can affect one another. Most of the time one aspect will lead to another ‚ so for example‚ if a child has a language barrier ( through a foreign language as their first one or late development of speaking) this can stop other children from playing or talking to this child ‚ what can lead to lower their self esteem and let him
