MYP 6 Science - Chemistry

MYP 6.2.0: Introduction - requirements and overview - Organigram of objectives

Objectives:

  • Understand that all matter is made of particles on the move
  • Know that matter in its different forms is made up of particles
  • Know that these particles are always in motion
  • Understand that the forces between the particles hold them together
  • Know that matter can be classified according to state
  • Know that the physical state is dependent on the temperature
  • Know that particles separate and disperse in solution (words: solvent, solute, dissolve)
  • Understand that dissolution is temperature dependent

Introduction

Revision of safety procedures, measurement and good laboratory practice.

What happens if we cut up a lump of iron into ever smaller pieces?

The ancient Greeks' thought experiment.

Discussion about the two theories:

  • continuous theory of matter
  • the particulate theory of matter

How can we decide which theory is more likely to be correct?

Note that theories (or hypotheses) can never be "proven", they can only be disproven. This is one of the great strengths of science. It allows science to progress by continually improving on current theory.

Evidence through experimentation may support a theory or hypothesis, but can never prove.
