so, I had a lab and it was "the effect of the concentration of a salt solution on the time it takes a grape to fall to the bottom of a 100 mL graduated cylinder." well my class didn't do the hypothesis before and the teacher told us to just dive in, and then gave is the assignment to complete the whole lab. Well typical enough I am having a really hard time writing the hypothesis -.- because I know what happens and the teacher said we're not aloud to use I,WE, YOU stuff like that, well how am I suppose to write a hypothesis if I cant say those things! just don't judge!

so i went to 3 grams of salt and got 12.8 sec.
6 grams-30.1 seconds
5 grams -18.4 sec

Writing a hypothesis can be very difficult and writing one after you've done the experiment is tricky. Technically you should write it before your experiment and then use your experiment to test your hypothesis.
Here's a great resource for developing a hypothesis:

My favorite way to write a hypothesis is a "If-then" statement.I'm sure you can develop a great hypothesis without the use of I, we, or you using this method. (Some of the example at this link use those words but not all of them.) Good luck!
