You were rushing to get to school on time and dropped your breakfast food! Choose one atom in that food item and explain the story of how it got there in the first place and what happened to it next, if no human picks it up and it remains in the environment. Follow your atom through at least one plant, one animal, and one decomposer.
There are possibly multiple paths your atom can take, but you only need to choose one for your story.
Explain how your atom gets from one point to the next.
You can use evidence from your notebook to help you tell your story.
You can use words and pictures to tell your story.

and dont just put a random answer

your answer would be “dry”

it's all four options.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
