I need help with some definitions Please help me

Postby PKFlash » Sun Nov 07, 2010 4:02 pm

I am in 8th grade and my science fair project is about how salty does water have to be to make an egg float and I need help finding these definitions: relative concentration, absolute concentration, stock, concentration. I tried looking them up, but I need definitions that I can understand.

Hi,

Here is a simple explanation of density:

After reading the one above, this page might help:

Here is the Science Buddies Project Writeup on the idea you are talking about:

If these resources have still left you confused try doing a google search on the term you are cibfused about, like “relative density”. Usually you will find a good answer in the top three or so hits listed on the search results.

Good luck,
