Chemistry is the study of matter and energy at the scale of atoms and molecules. As the most all-embracing discipline there is, it should be at the top of everyone’s list of must-learn subjects. Unfortunately, chemistry has an undeserved reputation for difficulty and abstraction. Any subject that encompasses as many components as chemistry is going to appear complex. The beauty of delving into the study of chemistry is the discovery of how organized, logical, consistent, and powerfully predictive it becomes—if properly presented.

Also check out how protons, electrons and neutrons were discovered at https://youtu.be/kBgIMRV895w.

Introduction video on the periodic table being explained to chemistry school & science students . The video explains how there are 92 naturally occurring elements, one for each kind of atom, and how they are arranged into a table according to their relative weights.

The expanded table is shown, and how this is abbreviated into the common Periodic Table. The division between metals, semi-metals and non-metals is discussed, with notable examples.
It also shows how the elements are arranged in rows and groups, the latter containing elements with similar properties, like members of a family.

About Atomic School:
Atomic School supports the teaching of Atomic Theory to primary school & science students.

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.

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.

Video transcript:
In the first video we saw that all the things in the world are made of incredibly tiny particles called atoms. And also that there are 92 different kinds of them. Most things have more than one type of atom in them, but when we do find something containing just one kind of atom, we call it an element. A nugget of gold is an element because it's made of only gold atoms.
The atoms are too small to see with our eyes, even using a good microscope, but if we could zoom in with a magnification of a billion times we could see the individual gold atoms. Each kind of atom had a shorthand way of writing it, called its symbol, using either one or two letters. The symbol for gold is Au, taken from the ancient Latin word it, aurum. The symbol Au could refer to either a single gold atom, or the element gold consisting of many gold atoms.
Scientists have made a list of all the types of atoms, starting with the lightest, hydrogen, followed by the next lightest, helium. Just heavier than these are lithium and beryllium. We could give each element a number showing its place in this list. Hydrogen's number would be 1 as it is the first in the list, helium's would be 2, and so on. Here are the first 20 elements in the list, starting with the lightest, hydrogen, and going all the way to the heaviest, uranium. Since there are 92 elements in the list, uranium's number must be 92

In this lighthearted talk Dominic Walliman gives us four guiding principles for easy science communication and unravels the myth that quantum physics is difficult to understand, it’s all in how it’s explained.


Dominic Walliman is a physicist, and award-winning science writer. He received his PhD in quantum device physics from the University of Birmingham and currently works at D-Wave Systems Inc., a quantum computing company in Vancouver. Dominic grew up reading science books and remembers vividly the excitement of discovering the mind-boggling explanations that science gives us about the Universe. If he can pass on this wonder and enjoyment to the next generation, he will consider it a job well done.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

When refraction is involved, your world can be reversed. Try this easy science experiment you can do at home with a glass of water, a piece of paper, and a permanent marker. 🧑‍🔬 How does it work? The bending of light waves as they pass through water causes refraction.

Refraction is the bending of light as it passes through a medium with a different refractive index. When light travels from air into water, for example, it bends towards the normal line (an imaginary line perpendicular to the surface of the water) due to the change in the refractive index of the two mediums. This experiment demonstrates the principle of refraction and how it affects the way we perceive the world around us.

Donald Trump threw next month’s TV debate with Kamala Harris into doubt over claims of bias at host network ABC News as he ramped up efforts to regain the initiative in the presidential election.

The challenger suggested that questions for the debate scheduled for September 10 could be leaked to Harris after watching a “panel of Trump haters” and asking “why would I do the debate against Kamala Harris on that network?”.
