CHEM - Chemistry: Videos & Interactives

Build 3-dimensional models of atoms viewing protons, neutrons and electrons

Explore a synthesis reaction, in which the atoms of two or more molecules rearrange themselves to form one product.

Explore the interactive periodic table by looking at characteristics of the metallic elements.

Whacky colour changes, magic disappearing water, blowing up dustbins, clouds of steam, thunder air explosions. Are you ready to fasten your seatbelts and enjoy the ‘explosive’ journey?

If you were able to make a substance change colour, or turn from a solid to a liquid, would that be magic? Andrew Szydlo leads us through a world of magical molecules and enchanting elements in this Ri event from Wednesday 23 April 2014. From a liquid that boils at room temperature to gases that are heavier than air, this family event is full of practical demonstrations of the magic of chemistry.

Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.
