Forms of Energy/ Energy Transformation/ Efficiency

Powerpoint explaining the 9 forms of energy, the difference between energy transfer and energy transformation, the law of conservation of energy and how to calclate energy efficiency. I've created this to teach a student I tutor outside school, and so it's definitely very content- heavy for within the classroom. However you could use just part of it and adapt it with more pictures, questions etc., which I will definitely be doing if I use it with a class.
