C1 The Particulate Nature of Matter (Combined Science)

What’s in a molecule? – the science of macaroni salad  from TED-Ed (3m 15s).

Some information on solids, liquids and gases (including a decent animation) can be found here. And this is a video on States of Matter from The Virtual School:

Science Bank 4 (Motion of Particles): Part 1 – Brownian motion (to 4m 45s); Part 2 – diffusion (to 9m 45s); Part 3 – changes of state (to 14m 15s):

IGCSE Chemistry: Topic 1 part 1 Particulate Nature of Matter  (6m 30s) & part 2 Diffusion (5m 35s), lessons by Sal Sciab.

Not on the syllabus, but interesting: the invisible motion of still objects:

C3 Atoms, Elements and Compounds (Combined Science)

But just how small is an atom? – from TED-Ed.

Here are some key terms for this topic: Key Terms C3

C3.1 PHYSICAL & CHEMICAL CHANGES

C3.2 ELEMENTS, COMPOUNDS & MIXTURES

C3.3 ATOMIC STRUCTURE & THE PERIODIC TABLE

A decent power-point, although we do not need to know about isotopes:

Short videos on what is an atom and parts of an atom (from The Virtual School) in English; and here’s one in Australian. Science Bank 17 (Atomic Structure):Part 1 – structure of the atom, Part 2 – atomic number & mass number, Part 3 – electronic structure.

The Virtual School have made a number of other short videos. Here’s one on atomic & mass number; this covers energy levels & electronic configuration. Some practice exam questions on atoms go here and here. And here’s a poem.

GCSE s-cool – Atomic Structure – revision notes & animations, practise exam questions & a revision summary. Skoool Chemistry – click on ‘5. Atoms & the Periodic Table’ for excellent lessons that take you through atomic structure; also a glossary of key terms. For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down to ‘17.Atomic structure, isotopes, electronic structure’.. Chemactive worksheets & answers just click on ‘Atomic Structure questions’.

C3.4 IONS & IONIC BONDS

In case you didn’t get that, here’s a lesson on ionic bonding. Some other Virtual School videos include the formulae of ionic compounds and their names part 1 and part 2.

C3.5 MOLECULES & COVALENT BONDS

A 15m lesson covering Ionic, Covalent & Metallic bonding from ChemistryKlipz (you don’t need metallic bonding in this topic):


A nice review of bonding and here’s a song:

And now we need another song. Oh, here’s Mr W singing his Octet Rule Song.

Revision sites covering Bonding:

GCSE s-cool – Chemical Bonding – revision notes & animations, practise exam questions & a revision summary. For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down to ‘18.Structure, Properties and Bonding of Materials’.

Skoool Chemistry – click on ‘1. Structures & Bonding’ for excellent lessons that take you through the topic; also a glossary of key terms. Worksheets from Mr Guch that cover Properties of Ionic & Covalent Compounds.

Topic 2 Molecular Biology

Here are some past essay questions: Topic 3 past essay questions

Paul Andersen describes The Molecules of Life in 10m 47s or Biological Molecules in 15m 20s.

Here are video tutorials for many assessment statements in topic 2 – and more are being added all the time. Thank you to Stephanie Castle (at UNIS, New York).

The whole topic in one monster powerpoint:
