We added leg bones onto our tracings and felt how our knee caps move as we put the parts together.
Then we used a rotisserie chicken for dinner (with dumplings - mmm) and for science!
First, we tried to break one of the chicken's big leg bones.
Even Daddy couldn't do it!
Then, we broke a little bone apart and looked at the marrow inside.
We examined the chicken's ribcage and talked about how it protected his lungs just like our ribs do.
Why doesn't this scientist's mother push up her sleeves? Ew.
Then we focused on our backbones and how they can bend and curve.
This is difficult as the Academy students are very ticklish.
We made a model of our spine: vertebrae, disk, vertebrae, disk, etc. with a spinal cord through the middle. (We used spools and paper circles)
We compared this with a picture and talked about how the disks protect the vertebrae from rubbing together.
Our spine can be straight or can curve and bend!
(Next time, we will leave less slack in the cord. Our spine was a little too bendy!)
Wow. all I can say is "wow." (And great job on the lemonade, too).
