Learner Profile
Thinkers - in this chapter, we will think critically and creatively to evaluate different points of view data
Objectives
find out how energy changes from type, but is never created or destroyed, and how work is done when energy is changes
Reflection
In this unit we have described how energy changes form but is never created or destroyed. We have described how work is done when energy changes, and calculated work done in some different situations. We have analysed simple machines for doing work, and we have explained how they make work more efficient. We have summarized the use of energy resources globally, and outlined some of the problems with global dependency on fossil fuels. We have taken action to increase access to a simple machine that can make a real difference to people’s lives -a water pump
