In the computer model you should see that there is a chooser called IRON-BLOCK-GEOMETRY. The chooser has options that allow you to change shape and size of the iron block. If you look at the rest of the interface, you will see there also the other widgets that let you control initial temperature, activation energy, water location, etc.
Design an experiment to test a question that you would like to investigate with this model AND that you think the model is capable of helping you investigate.
Be sure to run your experiment after answering questions 9.1 and 9.2.
