Heat ice and record the temperature and states of water at specified times. Plot a graph of temperature against time and relate sections of the graph to the states of water. Observe animations of water particles over time and explain the shape of the graph in terms of particle theory. This learning object is the first in a series of two sequential objects that are also available as a combined learning object.
Objective
1. Students observe the behavior of water particles during heating and explain properties of solid, liquid and gaseous water, and the processes involved in changing state, in terms of kinetic theory.
2. Students record and graph changes over time as water is heated.
3. Students interpret and explain the shape of the temperature–time graphs obtained when water is heated.
