Piaget s Theory Of The Stages Of Development Essay

Conservation is the ability to understand that as an object changes form, it does not change the overall amount or mass. In Piaget’s theory, he describes that during the pre-operational stage of development children are often incapable of understanding the concept of conservation, the ages in this stage generally range from 2-6 years old (Siegler Alibali, 2005). It isn’t until the concrete operational stage that children have the ability to understand conservation. During this stage children range from the ages of 7- 12 years old. In order to observe the changes in between stages, I chose to administer Piaget’s conservation of solid quantity to two different children. The task administered was to see if the two children would be able to see a transformation when I rolled out one of the two balls of clay. Piaget illustrated a stage model that explains the different stages of development starting at birth and continuing to twelve years old and onwards. In the tas k that I will be conducting it involves two of the four stages. The first stage is the pre-operational period. During this time children are exhibiting egocentrism as well as using symbolic representations, such as symbols or using signs. When children are in the pre-operational stage they do not have the ability to see transformations, instead they focus on fixed states. It is not until the concrete operational stage that children are able to see these transformations between states.

Jean Piaget (1896-1980) had a stage theory about cognitive development and how it works with children. There are 4 stages to this theory; sensorimotor, preoperational, concrete operational and formal operational. Piaget emphasised that they occur in this order. (Smith, Cowie, Blades, 2015, p. 446).

Love and Courtship in Shakespeare’s Day Compared to Modern...

Love and courtship in Shakespeare’s day compared to modern views on love and courtship. During the renaissance the Europeans saw love and courtship as two different yet important parts of life. It concerned expectations of families and communities, not just the longings of the couple. Shakespeare’s ‘Midsummer Night Dream’ gives us a clear view of a typical situation when couples fall in love and defy the rules. In the play there are four characters (Hermia, Helena, Lysander and Demetrius) all of which fall into one big love catastrophe. Both Lysander and Demetrius loved Hermia at the beginning of the play, Hermia loved Lysander and Helena loved Demetrius, as the play goes on both Lysander and Demetrius fall in love†¦show more content†¦In comparism dating is a much informal way to get to know you’re beloved. It is a private affair between two people who arranged to meet somewhere, usually in public. Such dates can be watching a movie in the theaters or having a meal together in a restaurant. Dating is a situation where the people get a chance to find out whether they are suited for each other before getting to know each other in a spiritual intellect. Dating can engage romantic talk, kissing, making out, and sometimes sex. Even without the preventive rules of courting dating can often lead to permanent relationships and latter on marriage. Overall dating is a product of a modern day society and is a generally evolved with behavior that has developed as a result of sexual freedom and disposing of religious, ethical and social standards. Every now and then A few Renaissance couples, ran away to be married in secret. They did this so they can marry for love. Defiant couples faced greater obstacles to elopement because many Anglican communities required parental consent. This applied especially for couples below certain ages. No matter how strict the rules were there were always some clever couples who managed to bypass them.

Explain and give examples of what is meant by the following: Acid Base Alkali pH Strong Acid / Base Weak Acid / Base Acid / Base Neutralisation 5. Consider the weak acid, Ethanoic Acid in a buffer solution containing Sodium Ethanoate CH3COOH CH3COO- + H+ CH3COONa CH3COO- + Na+ Explain what would happen to the pH if small volumes of hydrochloric acid or sodium hydroxide were added. 6.Experimentally determine by titration the concentration of sample of a sample of hydrochloric Answers: 1. Consider the reaction between gases carbon monoxide and nitrogen monoxide: 2CO + 2NO 2CO2 + N2 Using Boltzmann distribution and collision theory explain what would happen to the rate of a reaction if temperature and pressure were independently increased. Also explain what would happen is a suitable catalyst was used If the temperature increases independently, the rate of reaction will increase as the will have more energy and the particles will be colliding more. The rate of reaction will increases if they pressure is increased (Barnett and Harrison, 2013). If the pressure is increased, the reactant particles become more crowded, there is greater chance of collision, and the rate of reaction will increase. A catalyst is a substance when added to a reaction it will increase the rate of reaction. If platinum is added to the reaction, the reaction will be very fact. 2. Have complete Foundation Biology enzymes and rates, assessment criteria The chemical principles to analyse a typical analytical technique for the enzymes are the Investigate catalyse activity in plant extracts. Investigate of an enzyme-controlled reaction. Investigate to measure the effect of temperature on lipase activity (Oriakhi, 2009). 3.Consider the reversible reaction between nitrogen and hydrogen gases to produce ammonia gas the Haber Process N2 + 3H22NH3 - The forward reaction is exothermic Explain what is meant by Le Chateliers Principle and use it to explain what happens to the position of the equilibrium if: The concentration of nitrogen is increased Ammonia is removed as soon as it is produced Overall pressure of the system is increased Overall temperature of the system is increased Le Chateliers principle states that if a equilibrium is disturbed by changing the conditions, the position of the equilibrium shifts to counteract the change to re-establish an equilibrium. If the concentration of the nitrogen is increase then: The equilibrium will shift to the right, as the nitrogen will shift the reaction to the right (Haber, Kiwi and Kiwi, 2013). More ammonia will produced. Increase in the heat release. If ammonia is removed as soon as it is produced: The chemical concentration of the right will decrease. If Overall pressure of the system is increased: By increasing the pressure, the reaction will favour the forward reaction. The speed of reaction will increase. More number of Ammonia will produced (Haber, Bars and Schmitz, 2011). If Overall temperature of the system is increased More number of nitrogen and hydrogen will produced. 4. Explain and give examples of what is meant by the following: Acid Base Alkali pH Strong Acid / Base Weak Acid / Base Acid / Base Neutralisation Acid: Acids are the compounds that can donate hydronium ions when dissolved in water. Example: HCL Base: Bases are the substances, which produced hydroxide ions when dissolved in water. Example: Baking soda (Kauzmann, 2013). Alkali: Alkali are the substances which produces hydronium ions in water. Example: sodium hydroxide pH: it is a measure of the hydrogen ion concentration. Solution Strong Acid / Base: acids and bases, which are totally ionized when dissolved in water, are called strong acid and strong bases. Example: HCL is a strong acid. Weak Acid / Base: acids and bases, which are not completely ionized in water, are called weak acid and weak bases. Example: acetic acid is a weak acid. Acid / Base Neutralisation: When a strong acid and a strong base solution are mixed then neutralization reaction occurs. The product produced does not have the characteristics of both acids and the bases. 5. Consider the weak acid, Ethanoic Acid in a buffer solution containing Sodium Ethanoate CH3COOH CH3COO-+ H+ CH3COONa CH3COO-+ Na+ Explain what would happen to the pH if small volumes of hydrochloric acid or sodium hydroxide were added By the addition of hydrochloric acid, the pH remains the same. 6. Experimentally determine by titration the concentration of sample of a sample of hydrochloric acid using a known concentration of sodium carbonate A solution of hydrochloric acid is prepared and standardized against the pure sodium carbonate, and the percentage of the carbonate is determined in the sample (Moore and Langley, 2007). The percentage of Na2Co3 are calculated from the sample from two ways Molarity of the HCL: It is calculated by the following formula MHCl = moles HCl /liter = moles Na2CO3 x 2 (ml HCl/1000) = (wt of Na2CO3) x 2 / (mol wt Na2CO3) (ml HCl/1000) Percentage of the Na2CO3 in sample are calculated by the following %Na2CO3 = wt of Na2CO3 in sample / g sample x 100 References Barnett, C. and Harrison, M.

The Tale of Quetzalcoatl and Mel Gibson’s Film “Apocalypto” Essay Example

The Tale of Quetzalcoatl and Mel Gibson’s Film â€Å"Apocalypto† Paper During the period of Spanish conquest in the1500s, Meso-American civilizations were ignorant to the Europeans existing on the other side of the world. Due to their ignorance, the Meso-American civilizations created In regards to the tale of Quetzalcoatl and Mel Gibson’s Film â€Å"Apocalypto, the two stories taken place during the 1500s are bounded together through various mythic elements such as a clash of cultures and a connection to the sea.In the tale of Quetzalcoatl, Quetzalcoatl’s is greeted unpleasantly by the presence of Tezcatlipoca, the antagonist. During the story, Quetzalcoatl promoted the skill of crafts and the sacrifice of breads, flowers, and perfumes in opposition to the skill of war crafts and the sacrifice of tearing the hearts out of men and women. However, Tezcatlipoca upheld those practices of hostility that Quetzalcoatl disapproved of. Through this, there is a clash of cultures. During the ball court segment of the story, Tezcatlipoca transformed himself into a jaguar whereas Quetzalcoatl had fled. The cultures of Quetzalcoatl and Tezcatlipoca are in total opposition. Similarly in the film, Apocalypto, the cultures of Jaguar Paw and Zero Wolf were in heavy confliction. The tribe of Jaguar Paw and his father Flint Sky were of a peaceful people, while the culture of Zero Wolf believed in the conquering of less civilized tribes. The Aztecs also participated in the practice of human sacrifice.In addition, the two stories are connected to each other through the correlation of the sea. During both of the stories, Quetzalcoatl and Jaguar Paw each visited the sea during the end of their journeys. For Quetzalcoatl’s connection with the sea, it represented the next phase of life. As for Jaguar Paw, the connection to the sea brought the story back to the beginning but a deconstructive moment occurred when the Europeans arrived on the shores of the beach. Instead of a new beginning like Jaguar Paw hoped for, it was instead the b eginning of their end.Furthermore, Jaguar Paw and Zero Wolf depict the typical protagonist and antagonist story line. In Quetzalcoatl’s tale, Quetzalcoatl was the avatar of good and Tezcatlipoca was the avatar of bad. The same reference goes for Jaguar Paw being good and Zero Wolf being bad. In both stories there were constant rivalries between the two characters. In addition, to their rivalry was also a sense of commitment in both stories. Jaguar Paw was committed to his promise of coming back to his son and pregnant wife and Quetzalcoatl was committed to sticking to the ideals of non-violence. Moreover, two mythologens that occurred in the story were the promise to come back and the act of a quest. In the film, Jaguar Paw made a promise to his wife that he would come back which was followed by a divine reunion at the end of the movie. Jaguar Paw was constantly on a quest to survive for the sake of his tribe and forest during the film. Quetzalcoatl was also on a pursuit to c ome back to his people. During difficult times, people hope for a God to come back as their savior. Queztalcoatl came back through his resurrection.Will Durant’s observation, â€Å"A great civilization is not conquered from without until it has destroyed itself from within,† refers to the Aztec culture as depicted in the film as disproportionate in wealth as well as the hierarchy of their class system. I believe the observation also denotes the massive pollution and the images of natural resources being used up during the film. Though the film was set in the 1500s, the problems occurring in the Apocalypto are close parallels with what is happening in today’s world with third world countries and the abuse brought on by first world countries such as the United States.
