Work out #1-7 of the density practice problems on the handout given (the website can be used for help if you need it). If you are having problems, check out this link for a complete explanation (ignore the stuff on specific gravity).


When you are ready, complete this quizand have your teacher write your score on your handout and then sign you off. This quiz is meant to be done by yourself. NO GROUP WORK, NO CHEATING!!!

Adding salt to the picture investigation

ODMS 10/5


Use the animation below to explore why things float and sink. Take detailed notes for every step along the way (you are being graded on the accuracy and the content of your notes). Remember, I am most concerned with WHY, not just that you have something on paper.
- In your notes, focus on why you are predicting whether an object will sink or float and WHY you think that.
- I would rather you be wrong with a good thought process than right for no good reason.

When you are done, write a conclusion stating why object float or sink. If you need help, read this webpage.
