Life Science, Week 12

The Skeletal System

"Toe bone connected to da foot bone, foot bone connected to da ankle bone, ankle bone connected to da leg bone..."


Monday
If you can get a hold of the audiobook version of Dem Bones (our library had it), it's well-done and quite fun. At the end of the CD, you can play the book as a song.

For the "Bones" worksheet listed above, I made two copies of it. I cut out the labels from one copy and had Tessa glue them onto the other to save time and writing.


Tuesday

Tessa turned a pile of paper bones into a skeleton ("Skeleton Puzzle" from above).

Tessa examined chicken leg bones. She noted that they were strong and hard. Afterward, she placed most of the bones into a container. Then, I filled the container with vinegar. Over time, the vinegar will remove the minerals from the bones and they will become flexible. We will check on them in a couple of weeks.

After bathing in vinegar for a little over two weeks, the spongy parts of Tessa's chicken bones were decidedly softer and more flexible. The compact bone in the middle was still quite rigid, so back into the vinegar bath they went. We'll keep checking them.

  1. We learned a song with the major bones of the body. Here is one, but I wish she would have shown where each bone is in the video. (It makes it easier to learn.)

    Here is one we used (although we modified the lyrics slightly).

    1. I really like the second song. I wish I would have looked for something like this. I will definitely remember for our next go around.

      Maybe I can find a similar version on CD (or MP3). Tessa would love it.

      Thanks so much for sharing!
