Chemical changes occur around us, and inside us, all the time. When chemical reactions happen, one or more new substances are formed and energy is either given off or absorbed in the process. Spontaneous chemical reactions, those that occur naturally under favourable conditions release free energy, meaning they are exergonic. Endergonic reactions, by contrast, require net energy input to make the reaction happen. This excellent learning resource explores energy associated with chemical reactions, and cover areas such as activation energy and product formation, standard heats of reaction, thermochemical equations and Hess' Law, and specific heat capacity and calorimetry. It is essential viewing for any Chemistry student, providing clear explanations and easily understood visuals, including comprehensive chemical equations, about concepts that many students find challenging.

Energy is never created nor destroyed - just transferred from one form to another. It's one of the most fundamental concepts in physics, but can be one that students find challenging when first introduced to it. This video production uses an engaging presenter and familiar objects and scenarios - including skateboarding, tennis, vehicles and plant growth to explore different forms of energy, their effects on objects and processes and conversion from one form to another. Sections include what is energy, kinetic energy (including electrical, radiant and sound), potential energy and energy transformations. Students of Science at lower to middle levels will find this resource ideal for consolidating their understanding of these important fundamental areas.
