Overaching Goal / Enduring Understanding

All substances are composed of particles that are always moving and sometimes interact.

The particles (i.e. mass) and the energy are conserved. Opposite charged particles attract while similar charged particles repel.

Since science do measuring, numbers need to be significant and units needs to cancel.
