Revision of Higher Unit 1(a)
As we’ve just been over Unit 1(a), here is an online course covering most of 1(a):
- Introducing Rates of Reaction
- The Effect of Surface Area
- The Effect of Concentration and Pressure
- The Effect of Temperature
- Catalysts
- Enzymes
- Enzymes in Industry
Can you spot the parts of Unit 1(a) that are missing from these units?
Safety Song
New year – time to remind you all about safety. Here’s a song to help.
F3 Titrations
This video is the same titration we are doing in the lab – but we don’t do the back titration at the end.
Fantastic Bonding Video
The Chemistry homework was to compare and contrast ionic and covalent bonding. Two pupils produced a musical, another produced this video. Enjoy!

Solution Mining of Salt
We mentioned solution mining in class, but didn’t include much detail. Here is some more information:
Comic Relief
As I watched Comic Relief on Friday, I realised 4CH31 had raised enough to restore the sight of a child and pay for another child to attend primary school for a whole year. 1CH42 raised enough to pay for two children to go to primary school for the next year. Well done. Read about Chep and Sunday here:
Salbutamol Podcast (Ventolin Blue Inhaler)
Plenty of people use Ventolin inhalers and I used to ensure the quality of the Salbutamol that goes into it. Here is a podcast from the Royal Society of Chemistry.
Bakelite Podcast
We’ve looked at thermosetting synthetic polymers and now here is a podcast about the first, Bakelite.
pH of Rain at School
The pH of rain at the school will be updated every Tuesday and is available from the following link:

Unit 2 Functional Groups
We’ve met a lot of functional groups in Unit 2, so here is a song to help us remember them all.
SQA Advice for Higher Chemistry
Higher chemistry candidates’ responses to practical test questions (or PPAs) were “very poorly done” last year, suggesting some of them had “no experience” of various experiments.
The assessors commented: “In some centres, the benefits of effective teaching and learning with respect to PPAs were clearly evident, with large numbers of candidates producing very sharply focused answers; in other centres, however, many answers still suggest that the candidates have absolutely no experience of the PPA.”
Schools were also advised to do more to prepare Higher pupils for problem- solving questions and those which required more detailed explanations. Candidates could also improve their grade through “more attention to the rote-learning of the chemical knowledge on the course”.
Pupils were also reminded of the need to use their calculators correctly, especially if brackets were involved.

Ionic Bonding
See how well you manage to define ionic bonding.

Oil Products
Review of the properties of oil, and what combustion, fractions and the properties of alkanes and alkenes are. This is an overview of Topics 5 and 6 (and may be useful as a reminder for Higher).

Avogadro’s Hypothesis
Happy Birthday C60
Just as we were looking at the structure of Buckminsterfullerene (C60), Google have celebrated the 25th anniversary of the discovery of fullerene, the so-called “Buckyball.”
Water Podcast
As we’ve been looking at the bonding and properties of water, here’s a recent podcast:
Waterfall for iPhone
We’ve been looking at the structure of ice – here’s a game to help you remember how it all goes together.
The ice caps are melting, you have to rebuild them one water molecule at a time!
Waterfall is a simple, fun, and highly addictive game that teaches you about ice and nanoscience.
Hypnosis
Last night a hypnotist convinced me I was a dull grey malleable metal with an atomic number of 82.
I’m easily lead.
Ionic, Covalent and Polar Covalent Bonding
This animation looks at the differences between the three. When they talk about an octet of electrons, they mean a full outer shell.
Confused about Ionic, Covalent and Polar Bonds?
The “E.N.D.” they refer to is electronegativity difference. If the difference in elcetronegativity is very small or zero, then you have a pure covalent bond. As the difference in elctrongativity increases, the bond gets more polar (e.g. HCl, ΔE.N. = 0.9) until you end up with pure ionic bonding (e.g. NaCl, ΔE.N. = 2.1).

New Look for Dr T Chemistry Blog
I’ve changed the look to try to use more of the screen. If this doesn’t work for you, tell me about it by submitting a comment (comments will not appear on the blog).
Metals Revision Lesson
As we near the end of Topic 11, here is a revision lesson you can work through at your own pace.
Blast Furnace
Here is a link to an animation that will take you through a Blast Furnace. This is worth looking at just for the fantastic accent.
Covalent Bond Tutorial
Here is a tutorial with interactive flash animation for the formation of a covalent bond. I’d recommend pages 1-9 for everyone and the rest for those that want to understand it a little deeper.
Structure of the Atom and Isotopes
We’ve just been over these and here are some interactive units to help you revise:
Hazard Symbols
Once you’ve learnt all of the hazard symbols we did in class, how quickly can you identify the whole set:
Welcome to 2010/2011
Welcome to the new school year. I’ve tidied up last year’s posts and left a few of general interest.
Homework is listed in the homework tab above.
Chemistry Department Website has changed
https://pupils.highschoolofdundee.org.uk/dept/chemistry/
Everything that was on the old website is in new site. If you can’t see the F1, F2, Standard Grade, Higher tabs, you just have to Sign in first (top right of page). Same log-in and password as for logging on computers in school. Then click on your course and then all you need is available in the Shared Documents folder.
