Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by examining the two underlying forces that drive both endothermic and exothermic chemical reactions: enthalpy and entropy.

Introduction to Chemical Reactions


Introduction tutorial video to chemical reactions explains chemistry to school \u0026 science students by showing how the bonds of H2 and O2 molecules breaking apart and rearranging to form H2O molecules, and the telltale signs of a chemical reaction, including energy changes.
Warning: This video contains explosive sounds that might alarm you.

About Atomic School:
Atomic School supports the teaching of Atomic Theory to primary school \u0026 science students .
We provide lesson plans, handson classroom resources, demonstration equipment, quizzes and a Teacher’s Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don’t have to look anywhere else to implement this program.
Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class!
The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival.
It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences.
Atomic Theory underlies all the other sciences genetics, electronics, nanotechnology, engineering and astronomy so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth.

About Ian Stuart (Email: [email protected]):
The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom’s class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world.
Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths.
Ian has a Bachelor’s Degree in Chemistry from the University of Queensland and a Master’s degree in Electrochemistry from the University of Melbourne.
