D Make a prediction of the change in mass when an Ice cube melts. Develop into an explained hypothesis. How does the mass of water change as an ice cube melts?
D Measure the mass of an ice cube and the let it melt. Measure the mass of the resulting water.

T With every measurement there always random error.

T Particles can not be created or destroyed. What does the term 'conservation of mass' mean?
W There is a conservation of material and of mass for physical processes ie: in melting, freezing, evaporation, sublimation, condensation. NB: Students have not studied chemical reactions yet. Why does the mass change during evaporation?
A Draw a labelled diagram to show the particle arrangement for a material sample as a solid, liquid and gas. Like: http://www.chemistry.wustl.edu/~edudev/LabTutorials/Thermochem/images/SolLiqGas.jpg Check for number of particles being constant. Label melting, freezing, evaporation, sublimation, condensation. How can we represent the changes of state in diagram form?
