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

Freely chosen‚ self directed play. Refer back to assignment 1. The play cycle A play cycle begins in the pre conscious thoughts of the child‚ it is at the point of daydream where the playful impulse is created and given out as the play cue. Once this cue is taken up by a responding partner the play cycle begins. The metalude signals the start of the play process and while it supports a single play thought in the Childs consciousness it can change in seconds to become another playful thoughts or

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)

It is a theoretical study which explores the work of other scientists and philosophers. It also clarifies the implications some children with special needs have to experience both‚ orally and written.

fine motor skills; creative and constructive play are both particularly beneficial in this area‚ also play helps children to refine their motor skills when making toy figurines stand up etc. Play benefits children’s intellectual development as it helps then begin to understand important mathematical concepts such as number‚ matching‚ ordering‚ sorting‚ making and recognising pattern‚ adding and subtracting‚ and measuring. Role play helps children to explore aspects of their real life e.g a

Play is what children wants to do and what they choose to do when given the freedom‚ independence‚ time and space to determine their own behaviour. All children have a natural desire to play and will therefore play anywhere they are given the opportunity. Children’s play can be happy or sad‚ loud or quiet‚ calm or chaotic‚ creative or destructive‚ sociable or isolated and imaginative or real. Sometimes play can be risky‚ other times it will be boisterous and a lot of the time it will just seem plain
