The passive voice is not inherently bad. Most of your sentences should be in the active voice naturally.
This is how I view it, personally. I see it as a matter of style and emphasis rather than being grammatically correct or incorrect.

Also, it's quite common to use the passive voice in science reports/journals/experiments/etc.

But, can the word "happens" replace "is done"?

The control happens after the conditionals.

A comma might help the second sentence (but right, keep the passive):

Whenever something new is discovered in math and science or something new is made, the cubes rotate jobs.
Yeah, I agree with all of this although I might have replaced 'is done' with 'is tested' or 'is run' if you wanted to keep the passive.
