The start of The Periodic Games is just a day away. As attraction sparks between Chlorine and Sodium, President H2O fears that their new bond could incite revolution. Meanwhile, the other tributes are in training, forming covalent bonds that could help them survive in the Laboratoria, where only one atom will be left standing by the end. Show Less

When Chlorine Everclean voluntarily takes her sister’s place in The 75th Periodic Games, hosts Titanium Alloy and Caesium Lepton are taken by surprise! Chlorine isn’t as strong a contender as her little sister Fluorine, and the other 17 tributes are fierce competition. In this first episode, we meet the tributes offered by every group of the periodic table as they prepare to do battle in the Laboratoria. Show Less

Nanoparticles are tiny bits of material with a diameter between one and 100 nanometres. This clip explores the tiny world of nanoparticles and how their size and structure make them so useful, including the square-cube law and the relationship between volume and surface area.

In the hideout, Chlorine is trapped in Carbon’s buckyball, and Gold is put behind bars. When released, Ethanol takes him on a guided tour of the completed Project D. It’s giant DNA molecule, which will bring Planet Earth to life. Gold’s final attempt at destroying the molecule has little effect. Carbon’s heavies throw Gold and Chlorine into some aqua regia – and the pair finally bond. Show Less

In a secret location, Copper and Silver separate Chlorine from Potassium. Gold and Chlorine return to Carbon’s secret school – but cannot find Fluorine and Oxygen. Carbon appears, and Gold and Chlorine flee to a nearby bond shop where they meet Oxygen – now an Ozone molecule. Carbon has followed them and calls in Cyanide to dissolve Gold, and our hero is taken to the DNA coding hideout. Show Less

Gold finally meets the mysterious Chlorine and they try bonding, but to no avail. Suddenly Carbon and his heavies arrive on the scene. Gold and Chlorine are able to escape, but before they know it, Chlorine has ionically bonded with Potassium and Gold calls for backup. Water arrives and Potassium Chloride is taken to a secret location. Can the ionic bond be broken? Show Less

Agent Gold is assigned to investigate Project D, headed by Carbon who has trained millions of other atoms to develop this secret plan. Together with Oxygen and Fluorine, Gold penetrates Carbon’s secret school and finds atoms being drilled about bonding – vital information for Project D. Gold thinks it’s time to meet the Queen of the Bleach, Chlorine, but the others are not so sure. Show Less

What are things made of? Why do some substances dissolve and others don't? Why does heat affect some materials more than others? In this video, Elesapiens will join us to discover mixtures and the specific physical properties of matter, such as solubility, conductivity, hardness, magnetism... Through these properties, we will understand the uses and applications of the materials in our daily life. Show Less

In this video, students will learn to differentiate between physical and chemical changes. Students will be able to identify and differentiate physical and chemical changes in daily life, and interpret if a new substance or phase change has occurred during the change in matter. Show Less

Objective: To learn about components, concentration and properties of solutions. Learning outcomes - students will be able to: 1. Identify the components of solutions. 2. Define dilute and concentrated solutions. 3. List the properties of solutions. Show Less

Objective: To learn about the effect of atmospheric moisture and oxygen on food. Learning outcomes - students will be able to: 1. Understand how air reacts with food to cause oxidation. 2. Learn some of the methods used in the home and food industry to prevent food becoming rancid. Show Less

As we continue our history of the periodic table organisational system and discovery of the elements, this programme examines the elements lithium and beryllium. The characteristics of alkali metals and alkali earth metals are discussed in detail, with the help of graphics and animation demonstrating their similarities and differences. Students will learn why elements are organised into specific groups and their relations to the rows and columns of the periodic table. Interactive periodic table can be found here: http://www.ptable.com/ Show Less

Over seventy percent of the Earth is covered with water - around 326 million trillion gallons! Water is essential for life, it gives plants ability to create sugar for food and it helps humans regulate temperatures and nourishes and protects the brain, spinal cord and other tissues. Water is equally important to the environment due to the intricate balance of the water cycle. This programme takes an in-depth look at the chemistry of water and its different states and how each of them affects the world around us. Show Less

This episode of Shedding Light on Atoms looks at how the atoms of metals bond with the atoms of non-metals with what are called ionic bonds. We show how atoms can gain or lose electrons (in chemical reactions involving metals and non-metals), and that the number of electrons gained or lost depends on an atom's electron configuration. We finish by comparing ionic compounds with covalent compounds, and explain the difference—at the atomic level—between solids, liquids, and gases. Show Less

In this episode, we look at hot the atoms of non-metals bond together with covalent bonds to form molecules, introduce electron dot diagrams and structural formulae, explain how the electron configuration of an atom affects the number of bonds it can make, and finally introduce the topic of organic chemistry. Show Less

In this episode we look at how electrons are arranged within atoms in electron shells, and at how the Periodic Table is organised to reflect these arrangements. We demonstrate a variety of experiments which led to the discovery of electron shells and finish by taking a brief look at the size of atoms. Show Less

In this episode we take a look at the three types of particles that make up atoms and describe how they are arranged within atoms. Using live demonstrations and outstanding animations, we then look back at the experiments that led to the discovery of these three particles. Show Less

We begin this episode by comparing and contrasting metals with non-metals. We then describe how Dmitri Mendeleev, the scientist who devised the first Periodic Table, organised the elements not just into metals and non-metals but also into groups based on patterns in the way that they chemically react. Finally, we explain how Mendeleev was able to use the Periodic Table to predict the existence of, and many of the properties of, elements that hadn’t at the time been discovered! Show Less

The Shedding Light on Atoms series gives students the perfect introduction to the world of atoms. Using amazing demonstrations and animations we take students on a journey of discovery to explain not just what we know about atoms, but also how we know what we know about atoms! In Episode 3, The Discovery of Atoms, we demonstrate (using copper) how elements can join together to form compounds and how compounds can be broken back down into the individual elements that make them up. We take a look at the first (fairly) accurate list of elements ever published and explore the Law of Conservation of Mass. We crush some aluminium cans to show students what causes air pressure and then explain, using lots of different examples, the experiments that led directly to the discovery of atoms. Show Less
