About Atomic School:
Atomic School supports the teaching of Atomic Theory to primary school & science students .
We provide lesson plans, hands-on 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: ian.douglas.stuart@gmail.com):
The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year 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.

As a teacher, I like your videos as they are made delicately to deal with some concepts that are hard to introduce to the elementary learners. The level of explanations are kept to a manageable level to the learner to cope and learn the basics and still adequate to give them a consistent satisfactory answer to the numerous questions they may have at that stage. well done, and good luck.

Thanks Sam. From teacher to teacher that's high praise. My main adaption for elementary school students is to define Atomic Number in terms of the element's place in the list from lightest to heaviest ... which is easy for them to grasp. It means that they can meaningfully understand the PT immediately. The more modern definition re number of nuclear protons can come later.

Hi Luis. Great question. Hydrogen would "prefer" to join with an oxygen atom than another hydrogen atom, releasing more energy in the process. This means that the bond between H and O is stronger and more stable than between H and another H. So H2O is the preferred outcome from a rearrangement of bonds, rather than H2 and O2.

@@MohammedAhshanIt's a bit beyond the scope of a reply to explain bond strength, but it relates to how the negatively charged outer electrons of one atom are attracted to the positively charged nucleus of the other atom. With different nuclear charges, and electron positions, different pairs of atoms attract to different strengths. You can see some explanation here: kzfaq.info/get/bejne/p8lhh6qoysq3eZc.html

@@MohammedAhshan Oxygen is what we call more "electronegative" than other atoms. The electronegativity of an atom just refers to its tendency to bond with other atoms. The more electronegative, the more likely it is to form bonds. Atoms on the right of the periodic table (gases) are more likely to form bonds and be electron stealers and sharers. Oxygen, in fact, is more electronegative than any element except for one. Even in the water bond, the electrons spend slightly more time hanging out around the oxygen, giving water the characteristic bent shape portrayed (though not explained) in the video.

Thanks George. How about pointing out that sugar in water can be separated back into sugar and water by physical means e.g. evaporation. But Mg dissolved into water (making Mg(OH)2) would not produce Mg by evaporation. The ultimate test is whether a new substance is made ... then it's a chemical change. Sugar molecules remain sugar molecules when floating around in water.

Good day Ian. Cheers and thank you for this video production... a quick question about the events described at 4 mins 17 seconds.. Just wondering why the 2 oxygen and 2 hydrogen atoms didn't form Hydrogen Peroxide (dioxide)? I speculated that the single oxygen atom (O1 ) would establish a bond as well. Would you kindly describe the conditions on which this would occur? Peace
@AtomicSchool
@AtomicSchool 6 жыл бұрын
Great question! Actually, H2O2 would form, but only briefly because it is less stable than H2O and would soon fall apart. There are 2 reasons for this (1) The O-O bond is of lower strength (needs less energy to break it) than O-H bonds and (2) breaking one H2O2 molecules forms TWO fragments, which means that the tendency towards increased entropy (disorder) favours this process. You can see the various bond energies of various bonds at www.wiredchemist.com/chemistry/data/bond_energies_lengths.html.

H2O2 probably would form briefly, and also the original H2 and O2 molecules. However, the O-O bond strength is relatively weak, and this molecule would fall apart quickly under high energy conditions. However, the strong O-H bonds in H2O will keep it in tact. That's why water is so stable.

@AtomicSchool

Great question, Vinay. Indeed the old bonds can re-form, but they are not as strong as the new bonds. The bond energy of an O-H bond is greater than the combined bond energies of two H-H and a O=O bond, so when it forms it is more stable. (If you search for bond energy you can check this.) The high heat would keep re-breaking the old bonds, but the new stronger bonds would be the only ones remaining after the reaction is complete.

Real concern about misconceptions created in this video. Firstly, solids dissolving is a physical process not a chemical one. There is no chemical change as the solid that dissolves could be recovered by removing the solvents. Secondly by stating that "if the bonds absorb energy.....then the reaction is endothermic" causes areal and significant problem with students. Fundamentally bond breaking requires energy and is endothermic (energy input) and bond formation is exothermic and releases energy (energy output). It is the difference in energy input and output, therefore,that determines whether the reaction is Endo or Exothermic. If you are watching this as part of your Covid 19 science classes then be careful.
@AtomicSchool

Hi Steve. Dissolving of a solid can happen with both physical and chemical changes,. It's called 'dissolving' in both cases. Boiling is a physical change yet produces bubbles of gas. The enthalpy of some physical changes e.g. heats of solution of hydrochloric acid and sodium hydroxide, can be larger than the enthalpy changes of some chemical changes. Physical and chemical changes can share "signs" so it's not a binary situation. The video does not discuss the energy difference between bond breaking and bond making, only the net changes. Does it say that? Bond breaking and making needs another video. But because it shows both bond breaking and bond making earlier, it sets up the students for the next video. But at 8 minutes the video was already a bit too long.

@@GT-uh3ph Heating molecules makes them go faster, and have more kinetic energy. This means that when they crash into each other , they are more likely to bust apart and chemically react to form new molecules.

When ice gets converted into water, some people might think that it is an exothermic reaction as the temperature of ice is greater than that of gas but the real thing is that ice absorbs heat from its surroundings to break the bonds of the molecules. The molecules use up the heat to to gain kinetic energy and get far from each other to become water. And therefore, this reaction is endothermic.

As always, people who are conceited, pompous and self-deluding enough to include the word 'truth' in their handle (yours even including an admonition to others who you obviously feel to be less knowledgeable than you) denigrate others better and more accomplished than themselves, and yet actually expect themselves to be taken seriously. This gentleman (Mr. Stuart) has an outstanding reputation in the field of Education, he is an excellent teacher, and has developed a comprehensive system for instructing young students in this topic. He teaches internationally, and is very adept at creating educational videos that explain the primary concepts of the topic clearly and in an interesting, visually pleasing manner. What the hell have YOU ever done?
