Answer:
While I cannot write your essay for you, I will make you a plan.
First, decide what kind of science you like. Then search "name for the science of ___"
For this example, I will say I like to study plants. This is the science of botany.
If I had a job in botany, that would make me a botanist.
Essay start: what & why
If I could be any kind of scientist, I would be a botanist, which is a person who studies plants. I would love to be a botanist because I love the way plants look and I love being around them. (then I would continue reasons as to why I like plants. A paragraph should be about four or five sentences).
The next paragraph would describe my life as a botanist.
example: If I were a botanist I would study plants at my house as well as in my lab. I would be really good at taking care of plants, so I would have a lot of them. One plant I would like to have is _______. (then, continue ways your life would be different than it is now).
In the last paragraph, you could either continue ways your life would be different or list reasons it would make you happy.
example: As a botanist, I would also breed rare plants so that there are more of them, and I would study the uses of plants. Keeping a plant species alive would make me feel happy. If I discovered a use for a plant that no one knew before, that would make me happy too.
