Course Description

This course is a comprehensive introduction to Chemistry, covering everything you will need to know as you prepare for possible future exams.  It doesn't matter how much, or how little, prior knowledge of Chemistry you've got as this course will take you through all the necessary stages.

The content is based on the International GCSE specification as followed by thousands of students around the world, and will prepare you thoroughly for progression to advanced programmes.

In Section 1, The Principles of Chemistry, there are five video lessons, each one lasting about 20 minutes. The first lesson introduces the states of matter and atomic structure.  In the next lesson we progress to relative formula mass and chemical equations - don't be put off by these as everything is very carefully explained!  Lesson 3 covers chemical formulae, and we progress in lesson four to look at reacting masses, ionic bonding and covalent bonding.  Lesson five wraps up this part of the course with metallic crystals and electrolysis.

 

What are the requirements?

  • There are no essential course requirements, just a desire to learn more about Chemistry and a willingness to make the necessary effort!

What am I going to get from this course?

  • By the end of this course you will have received a thorough preparation in the principles of Chemistry. If you follow the course carefully the you should be looking forward to studying for your very first Chemistry exam - it's entirely up to you!

What is the target audience?

  • This course is intended for :
  • students who wish to follow a career in the sciences or medicine and who require really clear chemistry instruction
  • students who may already be following a course but who need additional support in order to successfully progress
  • anybody with a genuine interest in learning about the first principles of Chemistry!

In this lecture we cover the basic differences between solids, liquids and gases.  We also look at atomic structure, and what information can be extracted from a knowledge of the Periodic Table.

01:10  Solids, liquids and gases
07:30  Evidence of particles
10.50  Atoms and molecules
11.30  Elements, mixtures and compounds
13.50  Separation techniques
19.10  Atoms and atomic structure
23.35  Atomic mass and mass number
25.35  Isotopes
26.50  Relative atomic mass
29.10  The Periodic Table 
29:22

This lesson covers relative formula mass, including the use of the term 'mole' and how we carry out mole calculations.  We also then look at writing chemical equations to show the reactions being studied.

00:40  Relative atomic mass
02:42  Relative formula mass
03:30  Chemical formulae
07:36  The mole
10:20  Mole calculations
13:01  Using chemical symbols
16:35  Chemical equations 
13:44

In lesson 3 we really focus on chemical formulae - how we can determine these experimentally, how we calculate the formulae of hydrated salts, and how we can work out the simplest or empirical formulae.  We finish this lesson with a look at molecular formulae.

00:28  Finding chemical formulae - experimentally!
02:14  Empirical formulae
07:45  Water of crystallisation
11:00  Molecular formulae
23:55

Lesson 4 (also referred to as Lesson 3 Part 2) starts with an introduction to calculating reacting masses using knowledge from experimental data and chemical equations.  We then look at calculations involving molar solutions, moving swiftly on to consider ion formation in detail.  The lesson concludes with an introduction to ionic and covalent bonding.

00:38  Calculating reacting masses
04:34  Moles and molar solutions
09:30  Ionic bonding and atomic structure
11:45  Ion formation
14:10  Ion formation and the Periodic Table
15:25  Oxidation and Reduction (electron loss or gain)
16:24  Ionic bonding
18:25  Giant ionic structure
19:17  Covalent bonding
21:37  Giant covalent structures
22:40  Properties of ionic and covalent compounds 
18:04

The final lesson in this section begins with a look at the structure of metallic crystals and how the arrangement of particles affects the properties of metals.  This leads into a consideration of electrolysis, and we finish off with examples of electrolysis in action.

00:35  Metallic crystals
01:27  Metal properties
02:43  Introduction to electrolysis
05:50  Electrolyte or non-electrolyte?
07:52  Electrolysis in a solution
09:18  Electrolysis of brine (sodium chloride solution)
11:40  Half-equations
13:20  Electrolysis of molten lead bromide
14:17  Other examples of electrolysis 
Conclusion
03:36
20 questions

In this quick revision quiz you will be asked questions related to the content of Section 1.  Have a go, and see how you get on!

Instructor Biography

Graham Bray, Director of STEM, East Sussex, UK

I have been a teacher in the UK for nearly 30 years, and am currently the Director of STEM (Science, Technology, Engineering and Maths) at a large comprehensive school in East Sussex. To bore you with the qualifications, I have a Joint Honours Degree in Botany and Zoology from University College, Cardiff, and a PhD in Biological Sciences from the University of East Anglia. I was also one of the first Advanced Skills Teachers in the South East of England.

I am a passionate believer in life-long learning, and I will do whatever I can to encourage learning for all ages. Using videos to enhance learning has great potential, and I try to exploit this through my websites.

On a personal level I am married to a primary school headteacher, and we have two grown-up daughters. When not creating videos or teaching I relax (!) by working out at the gym, watching rugby and football, and doing a little work around the garden.
