Lower Sec

Sec 1 and 2

Strong science habits in Sec 1 and 2, before Chemistry gets serious.

For Sec 1 and 2 students who want to understand science, not just memorise it, and arrive at Sec 3 ready. In person at Upper Thomson.

Syllabus coverage

Every Lower Sec topic, in a sensible order

[PLACEHOLDER] Topic order to be confirmed by the tutors. Follows Lower Secondary Science.

States of matter, Elements, compounds and mixtures, Separation techniques.

Chemical changes

Physical and chemical changes, Acids and alkalis.

Systems and interactions

How lessons run

Four parts, every lesson

The same rhythm each week, so students know what to expect.

  1. 01

    Concept

    A short, clear explanation of the idea, with the why behind it.

  2. 02

    Worked practice

    We solve a question together and show how each line earns a mark.

  3. 03

    Timed questions

    Students attempt exam-style questions under time pressure.

  4. 04

    Feedback

    Marked against the mark scheme, with notes on what to change.

Worked example

What a full-mark answer looks like

One exam-style question, two answers, marked the way an examiner would.

Worked example

[PLACEHOLDER] Original exam-style question written by Chemify

Question

A student has a mixture of sand and salt. Describe how she could obtain dry crystals of salt from the mixture. [3]

Weak answer

1 / 3

Add water and filter it. Then heat the salt until it is dry.

  • B1Dissolves the salt in water and filters out the sand.
  • B1Does not say which part (the filtrate) contains the salt.
  • B1Heating to dryness is not crystallisation; no crystals form.

Strong answer

3 / 3

Add water and stir so the salt dissolves. Filter: the sand stays on the filter paper and the salt solution passes through as the filtrate. Heat the filtrate until it is saturated, then leave it to cool so salt crystals form. Filter off the crystals and dry them between filter papers.

  • B1Dissolve, then filter to remove sand.
  • B1Identifies the filtrate as the salt solution.
  • B1Crystallisation: heat to saturation, cool, dry crystals.

Marks follow the examiner's mark scheme: B = independent mark, M = method/reasoning, A = answer.
