YEAR 10Single - SUMMARY OF THE COURSE


 * __ Unit no. __ ||  __ Unit title __  ||  __ Duration (approximate) __  ||

(This document is “work in progress” and it is constantly updated)

===Time This is a suggested period of duration for each part of the unit. It is not intended to be rigid and more time is spent on a particular area if the needs of the pupils necessitate it. ===

Risk In any practical work risk assessment is crucial, the key is as follows:

 * ===B: Minor risk from hot objects (burns) === ||
 * ===E: minor risk from electrical equipment === ||
 * ===N: no significant risk === ||
 * ===S: specific risk assessment === ||
 * ===H: minor risk from heavy objects === ||

In year 10, students are usually split into three groups: 10Y is the single science group. The double science group is split into 10X and 10XX.

Homework
Students are given the chapter from the book. They are asked to read it, make notes on it and answer all the questions. They are also occasionally asked to complete classwork and plot graphs. During outings week they are asked to research their ISA Hypothesis and complete the Research notes sheet.
