Essay about Biology Milk Lab - 1303 Words

Bonnie Bell Mrs. Legary Biology P.6 21, Sept. 2011 Milk Lab Final This investigation consists of testing the reaction between milk, food coloring, and dishwashing soap. Different kinds of milk were tested, depending on the amount of milk fat content. The investigation was based on 2 questions. Lab one’s problem statement, using only milk fat and food coloring was: How does food coloring react in different kinds of milk fat? The second lab’s problem statement, using milk fat, food coloring, and dishwashing soap was: What happens when detergent is added to different milk fats and food coloring? The expectation is that the milk with higher fat content will have a more dramatic reaction. If the milk has a higher fat content,†¦show more content†¦| The first table shows the results between the milk and food coloring. In milk fat 1, the red food coloring spread fast and wide. In milk fat 2, the red food coloring did the same as milk fat 1. In milk fat 3, the red food coloring spread slowly in an oval shape. In milk fat 4, the red food coloring didn’t expand very big. In milk fat 1, the blue food coloring expanded slowly for a long time and stayed dark blue. In milk fat 2, the blue food coloring spread fast for a long time and stayed in one big glob. In milk fat 3, the blue food coloring looked like a spider web. It starts out light in color and expanded slowly getting darker. In milk fat 4, the blue food coloring got gets lighter as it expands. In milk fat 1, the yellow food coloring was more spread out. In milk fat 2, the yellow food coloring stayed in a little circle. In milk fat 3, the yellow food coloring stayed in a little circle and turned to an orangish-yellow color. In milk fat 4, the yellow food coloring stayed i n a small spot and didn’t spread. In milk fat 1, the green food coloring spread fast but not very big. In milk fat 2, the green food coloring didn’t spread very big. In milk fat 3, the green food coloring spread pretty big. And in milk fat 4, the green food coloring spread quickly. Day 2 dataShow MoreRelatedEnzyme Lab Report Essay2194 Words   |  9 Pagesonly work when a particular substrate fits in their active site.

Can Failure Leads For Success Praise Of The F Word By...

Can failure leads to success? In Praise Of The F Word by Mary Sherry, she argues that flunking students will motivate students to do better in school. The idea that flunking students will help one success in school is a categorical false. Although some advocates might argue that flunking does encourage students to do better in school. These silly dreamers are too dogmatic in their ideology. The three examples that exemplify that fluking does not help the students success are cheating, drop out of school, and depression. Flunking students can make one cheat in school. Cheating happens a lot in school because most don’t get caught therefore, students don’t understand the consequences of cheating. According to Sherry, â€Å"Passing students who have not mastered the work, cheats them and the employers who expect graduates to have basic skills† (Sherry). Most employers expect graduates students to know the basic skills, but yet some don’t. Overall failure does not help students success in life. For example, I have witnessed my classmate cheat in math class. Some students blame that it’s hard to understand the teacher’s teaching skill therefore one needs to cheat. The point is many students does not take the initial to go to tutor. Cheating has bothered me, especially when one tried to study and the other don’t but still pass the class.

Legal System and the Social Construction of Childhood Free Essays

In 1924 the League of Nations promulgated the first international agreement setting out the principles, which should inform the universal treatment of children. The underlying image of the child contained in the Declaration of Geneva was thoroughly imbued with a modernist concept of childhood. In particular children were seen as incomplete, non-social, weak and dependent. We will write a custom essay sample on Legal System and the Social Construction of Childhood or any similar topic only for you Order Now The Declaration, therefore, placed its emphasis on the duties of adults towards children. The UN Convention of the Rights of the Child (UNCRC), agreed in 1989, took this a stage further by making its provisions legally binding on national governments that ratified it. By 2003 this included all governments of the world except the US. The UNCRC, however, surpasses the modernist notion of children as a cultural other. It raises children’s social participation as a goal alongside protection and provision. Children’s participation has become an international rallying point for child advocacy. It is seen as capable of transcending differences in the social, cultural and economic conditions of children’s lives around the world (Davie, Upton and Varma, 1996; Flekkoy and Kaufman, 1997; Franklin, 1995; Hart, 1992; Lansdown, 1995). From one point of view the UNCRC represents a benign attempt to bring enlightenment and humane standards to all children. It has been used in this way and it is on these grounds that it draws enthusiastic support and even evokes a certain amount of zealotry. It has also been characterized as high in rhetoric but low in intensity. In this sense it is a highly suitable instrument through which declarations of lofty principle can be made but about which little needs to be done in practice. However, it is also the case that the children’s rights lobby is, for good or ill, on the forefront of the global spread of norms about childhood. As Boyden (1997:197) notes, these efforts have their precursors in the ‘civilizing mission’ of colonialism: â€Å"As the twentieth century has progressed, then, highly selective, stereo-typical perceptions of childhood – of the innocent child victim on the one hand and the young deviant on the other – have been exported from the industrial world to the South †¦ It has been the explicit goal of children’s rights specialists to crystallize in international law a universal system of rights for the child based on these norms.† The effects of this, she argues, are not always positive. Rights is a concept which is ultimately tied up with cultural values. Their successful implementation depends upon the existence of a compatible framework of meaning and an infrastructure of social and economic supports. The right to protection, for example, may translate well into practice when agencies, such as the police, are reliable upholders of law. When they are reliably corrupt it can be a recipe for oppression. Furthermore, some aspects of the concept of childhood contained in the UNCRC might also depend for their realization upon a level of economic wealth that many countries do not possess. As we have seen, for some countries international economic policy has led to deepening poverty, ill-health and inequality at the same time that social policy is urging the adoption of the rights of children. Perhaps, though, this is to underestimate the subtle processes that the UNCRC is enmeshed within. The different ways in which it (or part of it, Article 12) can be interpreted illustrate well how cultural globalization creates both diversity and homogeneity. It is, as Lee (1999) has pointed out, a document that has effectivity only because it is ambiguous. It is framed in such a way that its general principles are given a great deal of space for local interpretation. In fact, such was the level of disagreement among those who drafted it that this was the only way to make it acceptable to a wide range of countries with different cultural traditions about childhood. As Lee (2001a: 95-6) comments: â€Å"If the Convention had been intended to clarify children’s position, it would indeed crumple under this burden, but the Convention operates in a rather different way. Having generated childhood ambiguity, it then lays the responsibility for managing that ambiguity on the legislatures and the policy-makers of the states that have ratified it.† The representation of childhood found in the UNCRC has become more complex and ambiguous than the earlier Declaration. The protection and provision articles of the Convention still emphasize children’s need of adult support but, at the same time, especially through Article 12 of the Convention, children are pictured as social actors, not outside but inside society, not passive recipients but active participants. Role of the Legal System in Regulating children However, the contradictory effects of globalization do not all flow in the direction of self-expression and rights. From another point of view the twentieth century has witnessed increased levels of institutional control over children. The introduction of compulsory schooling and children’s formal exclusion from paid work signaled a historical tendency towards children’s increasing compartmentalization in specifically designated, separate settings, supervised by professionals and structured according to age and ability. Nà ¤sman (1994) has called this process the institutionalization of childhood. Throughout the twentieth century schooling has gradually been extended both ‘upwards’ (for example in incremental steps towards an older leaving-age for compulsory schooling) and ‘downwards’ in the growing emphasis on pre-school education and nursery provision (Moss et al., 2000.) Even leisure time is often framed in this way for many children because activities such as sport or music increasingly take place within some kind of institutional setting. It can be seen in the provision of after-school and holiday clubs that organize and regulate children’s activities under an adult gaze, channeling them into forms considered developmentally healthy and productive. Such phenomena have been noted across European societies. German sociologists, for example, have used the terms ‘domestication’ to describe the progressive removal of children from the streets and other public spaces and their relocation in special, protected spaces. They use the term ‘insularization’ to describe the decreased levels of children’s autonomous mobility around cities and the creation of special ‘islands’ of childhood to and from which they are transported (Zeiher, 2001, 2002). Within these institutions, but with significant variations according to national policy, it is possible to discern a struggle to tighten the regulation of children and to shape more firmly the outcomes of their activities. Schooling is a good example of this. In the last decades of the twentieth century the rather instrumental schooling regimes of the ‘Tiger Economies’ of Southeast Asia were held up as the model for producing economic efficiency and were widely influential in changing educational systems in Europe. I have argued elsewhere that this phenomenon represents a refocusing of modernity’s drive to control the future through children (Prout, 2000a). This tightening of control over children derives from a declining faith in other mechanisms of economic control, combined with increasing competitive pressures from the world economy. The intensification of global competition and the intricate networking of national economies erode the state’s capacity to control its own economic activity. In such circumstances, shaping children as the future labor force is seen as an increasingly important option. This, after all, is exactly what supply side economics is about but, as far as children are concerned, it often leads to attempts to regulate and standardize what they learn and how they learn it.
