Starting at Unit 2?

My chemistry teacher is a complete waste of time. He is absoloutely hopeless, but now he's elected to start the course at unit 2, which means we are straight in at Stoichiometry. I am kinda struggling, because we don't have any of the necessary theory to apply to the questions - for which he thinks we must develop a suitable technique.

Seeing as there's a lack of textbook for the course, does anyone have any resources that I might find useful?

TIA

Most of the stoichiometry in unit two is revision of Higher, so knowlege of unit one isnt really required. However, if you are looking for resources, Scholar has a lot of questions and answers (ie 20 tongue.gif )...it doesnt really explain all that well though unsure.gif

We're doing exactly the same thing at the moment! maybe it's a standard sort of thing that a lot of schools do?

what they do in my old school is one teacher teaches units one followed by unit 3 for 3 periods a week and then another teaches unit 2 for the remaining 2

Last year we did them all in order 1,2 then 3 unit 1 spent too long on, unit 2 dragged in and unit 3 we finished like a week before the exam!!! unit 3 was the best one though, well at least most interesting. Unit 2 is quite hard with all the equations and stuff though. The learning outcomes posted on here are really good for revision though!

The way we are working it is 2 periods of unit 1 and 3 periods of unit 3 per week and I think its a good idea so far.

I've started from unit 1 but the rest of my subjects are jumbled up. I don't quite think my teacher likes doing it this way though, he's been complaining about the lack of experiments. But he's been trying to make up for that by gasing us.
("This is the most poisenous chemical we'll be working with" [H2S] Then he comes round and wafts it under our noses "It's more poisenous than hydrogen cyanide, you know, the one the Americans use for gasing people)

We have unit one being taught by one teacher, and they get in a retired teacher a period a week to do unit two because he's the only one who can do thermodynamics.

We got given a book with notes in it, it's pretty good. It might be on ltsscotland, if it's not there I have no idea where you'll be able to find it.

Chemistry Teacher here. As someone said earlier, the calculations done at Advanced Higher are the same as those done at Higher. However, they are placed in the context of the practical work you will be expected to have done. The 'difficulty' will come from seeing the (several) steps that will take you from the practical data provided to the required answer. For example, from a concentration of MnO4- to the %Mn in a steel paper clip.

There are, however, a couple of publications that should help. The Guide to Practical Work, I've mentioned in an earlier thread, will give you the knowledge of the Practical Techniques to put your calculations into context.

It also gives help with Errors and how to write PPA reports. The PPA's are where you are supposed to really learn how to do these calculations.

The other document is the Advanced Higher Support Notes Unit 2. Your school should have both these publications, but I will put copies on my webpage that you can download. Any problems, contact me by email and I can convert them into pdf if necessary.
