During the experiment‚ we made observations and possible explanations on why Copper(II)Chloride Dehydrate and Aluminum foil created a chemical reaction. The observations were made by using Copper Chloride‚ Aluminum foil‚ and Distilled water. Before the Aluminum

Introduction The purpose of this lab is to be able to observe the reaction rates of different chemical substances‚ by looking at which substance is the fastest reactant. This is what chemical kinetics is. Reaction rate is the change in the concentration of a reactant or product in a chemical reaction per unit time. In this lab the requirement was to be able to calculate each Average reaction rate which is the change in reactant or product concentration at a given time interval. Some equations that

Observing Leadership Style & Task Process Behaviors As the meeting of choice‚ our monthly assembly for the side project between friends began fairly casually. The meeting starts with opening comments initiated by the leader. The approach here is free reign or laissez faire. While it does impose ideas or functions‚ it allows the other members of the team to be openly expressive and creative. Once the opening phase is complete and the ideas have been thoroughly stirred around‚ the leader

Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

inclinations. Many people and parents believe children just learn self control on their own and will eventually grow out of their bad behaviors and everything else. The truth though is whatever the teachers are teaching them in a regular school is not helping them with self control at all. Well on the other hand‚ self control can be taught to young children to fix bad behaviors and low test scores. The big question though is can self control really be taught to children at an early age? Studies and programs

We must safeguard children and young people as they are unable to protect themselves alone and are far more vulnerable to things such as abuse and neglect than adults are. It is our duty of care to protect children and young people from physical abuse‚ emotional abuse‚ sexual abuse‚ verbal abuse and neglect. We must be able to identify early on the signs and symptoms of abuse or neglect before the child is to get in any serious danger. A child’s sudden change in behaviour could be a huge sign of

a. Explain the importance of safeguarding children and young people It is important to safeguard children and young people as without this protection their future could be negatively affected. Their health and development could be impaired as its possible they could withdraw from family and peers which would affect them emotionally and also developmentally fall behind with educational milestones (if school is missed). Children and young people need to be protected from neglect and abuse and

Explain the importance of resilience in children and young people Resilience is a mixture of nature and nurture. Attributes that some children are born with‚ such as good intellectual ability and a placid‚ cheerful temperament‚ are associated with resilience. Children who are born prematurely and/or with disabilities‚ who cry and cannot be comforted‚ who cannot sleep or who will not accept being held are more vulnerable to adversity and may be less likely to be resilient. There are‚ however‚ many
