Chemistry in the development of a current technology (internal)

Internal 3 credits Applied chemistry Research Links Vocabulary Technology

AS 91163, 3 credits. A research report on the chemistry behind a current technology. The standard is explicit about the ladder: Achieved gives an account, Merit makes and explains LINKS between the chemistry and the technology's development, Excellence evaluates that influence.

1 Reading the notation

Account → links → evaluation of influence — three distinct verbs, not three amounts of the same thing.

📖 Terms the schedule grades you on

4 terms
Demonstrate understanding (Achieved)
Process and interpret information to give an account, using vocabulary/symbols/conventions.
In-depth (Merit)
Make and explain links between the chemistry and the technology's development.
Comprehensive (Excellence)
Evaluate HOW the chemistry influenced the development of the technology.
Current technology
Technology in use today — though the historical discussion can span all of human history.

2 Choosing a technology with real chemistry in it

The chemistry has to genuinely determine how and why the technology developed.

What the account needs

  • Balanced equations where relevant.
  • The structures or bonding involved.
  • The reaction type and any energy changes.
  • The properties that follow from the structure.

3 Building the report

Structure → property → application → development — each arrow is a link.

The chain that produces links automatically

  • STRUCTURE: what the substance is, its bonding and structure.
  • PROPERTY: what that structure makes it do — conductivity, reactivity, stability, solubility.
  • APPLICATION: how the technology exploits that property.
  • DEVELOPMENT: what this made possible that was not possible before, and what still limits it.

4 Evaluating the chemistry's influence

A genuine judgement about how much the chemistry drove the technology — constraints included. ✕

More links instead of an evaluation

Adding a fourth and fifth well-explained link is still Merit-level work if none of them steps back to judge the OVERALL extent of the chemistry's influence. Excellence needs a verdict: how much did the chemistry itself shape this technology's path, and where has it been a limiting factor?

Practice

Recall it first, then use it — testing yourself builds the memory, where rereading the notes above only feels easier.

Recall and application shuffled together — you have to work out what each item wants before you can answer it, which is the part the exam actually tests. Both kinds feed the same spacing schedule, so anything you miss comes back sooner.

Say the answer out loud before flipping — that attempt is where the learning happens, even when you get it wrong.

Exam-style only. Instant feedback, shuffled each attempt, best score saved on this device.
