Students will explore,solve density from the web resource.
They will use the URL:

http://www.explorelearning.com/index.cfm?method=cResource.dspDetail&Resou...
Or they type middleschoolscience.com>physics>density

Questions they need to answer:
1. Does the mass of anject tell you whether or not the object will sink or flaot in water?
2. Why do we need to know density when we are studying the weather?

Mitchelle,

I liked the web and your questions about density. My question is how are you going to tie in the datatools with your work? Are you going to make the children use excel to show their work? Please comment.
