Gummy Bear Osmosis Lab Report Essay Example

Gummy Bear Osmosis Lab Report Paper Tiffany Parker Mr Taylor Biology 6th period 2/12/15 Gummy Bear Osmosis Lab Report Purpose: The purpose of this lab is to measure the amount of Osmosis in different types of solutions and to see how a cell would react in different types of solutions. Hypothesis: My hypothesis for this experiment is that the Gummy bear will absorb more of the plain tap and sugar water and the salt water will shrink the gummy Procedure: Materials- 3 clear cups, one spoon, 3 gummy bears, timer, tap water, salt, sugar, ruler, and beaker Fill one cup of tap water, one cup f tap water and salt, and one cup with tap water and sugar. Measure the 3 different gummies height, width and weight balance before putting them into the solutions. Put a different gummy bear in each of the solutions. Time for about 24 hours then remove each one with a spoon carefully. Now measure their height, width and weight balance again. Data Collection: BEFORE Salt water gummy Sugar water gummy Tap water gummy Height CM Width LLC Weight balance g AFTER 1. CM CM CM . CM 2. CM leg 3. G Representing Data: Conclusion: My data clearly shows the differences between the height, width, ND weight balance before and after the lab. Also that the salt water gummy height was the only one to decrease, while the Tap water gummy increased the most (CM). I think the Tap water increased the gummies size the most because its easier for the gummy bear to soak in plain tap water than sugar water because the gummy already has the sugars in it.

The sugar water gummy barley increased because I think the gummy already has sugar in it so I really just absorbed a bit of the water. I would like to point out not only did the gummy shrink in the salt water but I also was very sticky unlike the tap water which was a little slimy and the sugary water gummy felt a like sticky but not that bad. The Weight balance of the gummy bears can most accurately show you how the different solutions affect the gummy bear (cell) because the any substance can change the height and change the width yet it could still be the same weight yet if you look at the weight you can determine that the gummy bear (cell) if is a different height and width. In this lab diffusion can be taken place just as cells o, the gummy take in the solutions and eventually the solution will escape if not kept in solution. The lab is using the gummy bears to show how cells work because cells can take in more and less concentrated solutions just as gummy bears do but it leaves a different appearance depending on the solution. In conclusion my hypothesis was partly correct, the gummy did absorb more tap water and the salt water did decrease the size of the gummy but, the sugar water gummy did not increase as much I thought it would have, it absorbed very very little so it didnt change any appearance much at all.

Special educational needs provision Essay Example | Topics and Well Written Essays - 1750 words

Special educational needs provision - Essay Example The Education reform Act of 1988 marks an historic and radical revision of education in England and Wales based on an ideology starkly at odds with that which guided the system’s development in the previous four decades (Cor, 1996). The reliance on market forces as a mechanism of quality control and the unprecedented degree of centralized control of the curriculum, for instance, are principles calling for revolutionary changes in the way teachers operate. Their impact has been made more difficult to assimilate by the speed with which these policies are introduces and there political sponsors refusals to acknowledge what may educationists have argued are potentially dangerous implications. And also in this, special education is not only reflected as a broader educational concept but also as a broader social and political concept. (Len, 1988). Special educational needs are defined in the 1993 Education Act as learning difficulties that call for special provision besides that rou tinely provided in mainstream schools (1993 Act, para 156). If what is provided routinely does not meet the child’s learning needs then a statement of SEN, specifying additional resources will be required. The inexorable rise in the number of children with statements, combined with increasingly high levels of parental expectations concerning special educational needs provision, has led to demands on the founders, the Local Education Authorities (LEAs) which can no longer be met (Ann, 1997). met (Ann, 1997). Recognizing this, the 1993 Education Act proposed a Code of Practice to clarify what special educational needs provision should be made generally available in mainstream schools. Children with special educational needs form a substantial minority of the primary school population. The Warnock Report (DES, 1978) suggested that 20 percent of children will have special educational needs at some time during their school careers. This figure, derived from standardized test and survey data, has been criticized as arbitrary and self-fulfilling but is supported by a wide range of research evidence (e.g. Croll and Moses, 1985; Mortimore et al. 1988; Shorrocks et al, 1992). Thus children with a variety of special educational need form a significant group and one that may draw disproportionately on scarce educational resources. To be precise, in 2005 around 18% of all pupils in school in England were categorized as having some sort of special educational need (SEN) (1.5 million children) (Ann, 1997). Around 3% of all children (250,000) had a statement of SEN and around 1% of all children were in special schools (90,000) - which represents approximately one third of children with statements. With such a large number of children involved, it is important to recognize that many children are receiving the education they need in an appropriate setting. It is equally important, however, to highlight the difficulties faced by a large number of parents for whom the system is failing to meet the needs of their children. The influence of the Warnock Report was not restricted to a new conceptualization of special educational needs; it also made wide - ranging recommendations about the way in which special educational provision should be developed. The Committee argued that the provision should be seen as 'additional or supplementary" rather than 'separate or alternative' to regular education, and described a continuum of settings in which it might take place. For most children, their needs would be met in ordinary classrooms, with additional support as required. The Warnock Committee (DES, 1978) heralded a
