who ever though boiling water was simple?

1. What? you didn't complete last weeks homework?!?  Go back and make sure you really did all that you were supposed to, and that includes writing in your science journals --did you copy the graph on page 492?  Re-read that paragraph too.  And then  go here and press play...

4.   Worksheet from class:   Comparing Celsius, Kelvin and Fahrenheit temperature scales, with math (use calculators).  [9/5 can also be 1.8].  Get help if you need it,   Answers  are here

On Thursday we will make our own thermometers, so if  you have a small jar or bottle with lid, bring that to class -- not too big and thinner is a little better.  Baby food jar, spice jar,  just not huge, and I will have some extras if you can't find anything.
