Several videos illustrate physical processes or chemical processes. Students use a guided-inquiry activity sheet to classify the starting and ending substances and to identify the processes as physical or chemical.
Liquid Water Molecules Animation at the particulate level of representation RoyTasker VisChemProject. An excellent and accurate representation and animaiton.
Computer simulation of the three states of matter of water as represented by a particulate view: a cluster of atoms or molecules and a simple view of the transition states between the phases of matter: melting, boiling, condensation, freezing.
Heating water from room temperature to boiling water and measuring the temperature of the liquid versus time produces a portion of the Heating Curve for water.
