The second day of Modeling Your World began with the students brainstorming about models. The students formed groups and were given each a rope and they tried to come up with as many ideas of things ropes can model. The students then iscussed with the other groups what they found and, in the process, came up with several more things they can model.

Next, the students used MacSpartan® to model different chemicals. The students began with a model of the water molecule and moved on to a model of TNT. With the aid of MacSpartan the students were able to learn more about each molecule and its properties.
