When I learned about passive voice, scientific writing was often mentioned as an explicit exception. What you say makes sense when you are abstractly describing something that happened, but also I'd argue that "We added 30 grams of goop to the beaker" or "Added 30 grams of goop to the beaker" is clearer than "30 grams of goop was added to the beaker". Depends on the context and style conventions of course, but often passive voice is still poor/indirect writing in many scientific contexts.
