Although not directly related to atomic structure, this experiment led to the determination of the mass of the electron.

resources
Here is a simple yet instructive interactive for Millikan's experiment.
Best process is
1. Record both voltage and radius of oil droplet in a spreadsheet
2. For each, determine the mass by calculating the volume and using the supplied density
3. Work out the charge for each by equating the two forces (electric field and gravitational field) (You will have to determine the electric field from the voltage)
4. Carefully examine the charge values  they are multiples of a set value

Let's give credit due, The Geiger Marsden experiment led to the planetary model of the atom as proposed by Rutherford.

pHET
This pHET interactive allows you to see a model of the Rutherford scattering and compare it to the Plum Pudding model

In this video, using a 3D printed model I demonstrate how the scattering experiment works giving you the viewer to participate. I also then discuss how science relies on the development of models that explain observations and are able to therefore predict outcomes

What hold a nucleus together? Why does it not just fall apart? In this video I discuss the Strong Nuclear Force, in simple terms that holds the atom together. This concept is essential to explain radioactive decay, fission and fusion.

There are a number of ways we can explore this concepts further.
One aspect of most high school physics course on kinematics, is that they only concern themselves with constant acceleration. In reality however, acceleration, like displacement and velocity, can chance with respect to time.
Velocity is the rate of change of displacement. Unit: m/s^{2}
Acceleration is the rate of change of velocity.
So what is the rate of change of acceleration?
The answer to that is the jerk. So slope of the acceleration vs time graph is the jerk. Unit: m/s^{3}
We can go further. What is the rate of change of the jerk?
Well it's the snap. Unit: m/s^{4}
Can we go further? Yep. The rate of change of snap is the crackle. Unit: m/s^{5}
I think you can guess the next one.
