DUE IN 10 HELP John was asked to create a model that showed the difference between conductors and insulators. The model he created is shown below. Evaluate his models and his description of his model to determine if John shows the difference between a conductor and an insulator. Describe what is good and what might be improved in his model.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.
