I made a simple worksheet about density. 5 pages. Two of info, one table of values, a page of questions and my answers. I have now added a keynote and powerpoint version.

I made a wacky presentation showing some constellations, and a tiny bit of information on the solar system. I also made a movie of the presentation set to music. Just for fun really.

I made a crazy video about hydrolysing water with a hofmann voltameter Note: the youtube version is free. I only put a price on the download because you have to do that for the resource to appear on TES pages.

The traditional textbook graph of this data is very confused. I feel that my presentation of the data emphasizes the role played by hydrogen bonding more clearly. The influence of atomic size on boiling point is also clearly shown by the bp of the noble gases.
