Body Worlds at Buffalo Science Museum
I took my 9 year old son (a fourth grader) to see Body Worlds at the Buffalo Science Museum. It was a fascinating visit. They have over 20 bodies that were donated to the Body Worlds company that have been preserved by "plascene" (whatever that is!) so they can be displayed. The bodies are in various sport poses from dancing to skiing, with the muscles, ligaments, bones and blood vessels exposed so you can see and understand how the human body works. Among the exhibits are lungs that have turned black because of smoking, an enlarged liver and an artificial heart.
There are only a couple of more weeks before this traveling science exhibit moves on so I recommend trying to fit a visit in if you can. I got my tickets online at www.sciencebuff.org.
The rock and mineral exhibit was also very interesting, as was the mandala - a sand picture made in the 1990's by the Dali Lama's monks.
