You can see a video from 2008 that we filmed of a hatching.....keep on your voloume because the kids voices are so little and cute!
I showed the difference between the two genders in this past post.

This week's Science Sunday comes directly from Steve Spangler Science.
Items needed: jar or glass
coins
index card
interested small children
The object of this experiment was to get the coin into the jar without touching the coin.
We got a penny into a jar without touching it, using Newton's Law of Inertia.
The first Law of Motion states that an object at rest will remain at rest unless an outside force acts upon it. When you "flick" the card---on an even path---out from under the coin, there is no force on the penny, only on the index card.
This has great WOW! appeal. Sure to impress all the big brothers and sisters---and even the grandparents.
