Guy my little 4th grader sister wants me to help her with a topic for her to research but I have no idea on what it should be about or what to write. Please help us Asap she told me it was due on Tuesday

Of course what subject is your sister studying and what are the requirements concerning her project?

Explanation:

I need this information to help you decide on a solid topic and a good overall project.

I can list some ideas in the comments when I have an idea over what it is exactly that you are doing :)

onto a large boat, and mark the water level that the boat sinks to. then, take the elephant out and put a bunch of marked weights onto the boat until it reaches the same water level. add up the masses of the weights to get the weight of the elephant.
