Question

You will use the PhET simulation to investigate the relationship between shape, electronegativity and polarity. Go to the following URL:https://phet.colorado.edu/sims/html/molecule-polarity/latest/molecule-polarity_en.html.

A. Start by clicking on theTwo Atomssimulation.

Turn on the electric field.
Change the electronegativity of both atoms and observe the movement of the molecule.
Which end of the molecule is nearest the negative plate and which is nearest the positive plate?
Drag the atoms into different positions. What effect does that have on polarity? How do you know?
How can the molecule be made themost polarand theleast polar?

B. Repeat the investigation above with theThree Atomsexample. Pay close attention to shape as you drag the atoms into different positions.

First, summarize what you discovered using the PhET simulation in a sound paragraph. Your summary should use the concepts of molecular shape and electronegativity to explain the meaning of polar and non-polar and how molecules can be classified into those two groups. Also summarize the steps you took in the simulation to arrive at your conclusions. What symbols and data did the simulation provide?
Second, take a stance on the following statement: “All molecules with polar covalent bonds are polar molecules.” Do you agree or disagree? Why? Use the simulation to support your argument. Describe what you did and why your experiment supports your stance. If you can find real examples to support your argument, list some of those as well.

Experiment findings:
As per the instructions given in the assignment, I opened first the given link.
Next I clicked two atoms, turned on electric field.  I could see A on left side and B right side connected.
I could see now two board on either side left marked negative and right positive.
When I increase electronegativity of A, then A went to right side while B left side thus reversing. 
The arrow from B towards A increased in length whenever I increase the electronegativity of A
When I increased electronegativity of B, more than A, then again A came to left and B right.  
By repeating this for different levels I could guess that the more the electronegativity the more the atome goes near negative plate.  i.e. nearest the positive plate the molecule with more electronegativity was there.  The molecule with less electronegativity tend to be near negative plate.
This I repeated for a number of times and confirmed that electronegatively charged atoms/molecules go near positive plates and vice versa.
