Science Sunday: parts of the bone model

One of the lessons I’ve been looking forward to is our bone study, because I couldn’t wait to make our parts of the bone model.  I’ve pinned several good ideas onto my anatomy board:

•  Science Matters bone model
• angelicscalliwags layers of a bone model
• Weiser Academy bone model
• All Things Beautiful bone model

I had plans to use a pool noodle for ours, but we didn’t get one at the store, so Plan Play dough came into being.  I mixed up a batch of play dough, separated it out into 3 bunches and let the kids start mixing the colors in.  Eventually their hands were covered in dye, but we had 3 distinct colors.

 

Layers of the Bone model supplies: toilet paper roll, 2 different colors of play dough, roper or yarn

First we flattened out two different colors of play dough, making one layer slightly thicker than the other.  Then we cut up the toilet paper tube to be able to put the layers inside together.

Then we placed the two layers on top of each other, with the thicker layer on the outside, then rolled the play dough around the rope.  We didn’t press too hard, so the colors could be easily separated out again for play time.

And Voila!  A nicely made layers of the bone model, we talked through what each of the layers were and what its’ job was (perisateum, compact bone, spongy bone, and marrow).

Then after taking pictures the kids happily played in play dough for an hour.  I waited a few days, and then did the follow up activity (this was more because we went tubing on Wednesday and didn’t get home until long past bedtime).

You’ve made all those layers of a bone, now can you remember what they were?  To make sure they didn’t freak out too much, I put all of the names up on our dry erase board, and they copied and labeled away.  Poor Superman had just woken up from an impromptu nap, and was not happy.  I got him a cup of hot tea, and a few minutes to calm down, and he finished the assignment.

 

I was very happy to discover that a few days later they still remembered the various parts (with some prompting on names) and could tell me what they did.  A lesson well learned.  Come back next week to see all the first aid information we’re going to learn, or if you don’t want to wait, then check out the Angelicscalliwags post I linked to earlier.  I’m freely stealing from her great ideas.

 

 

 

 

 

Let’s see what others did this week: Each week I’m spotlighting a few posts that were shared previously.  Many posts get linked up later in the week and they don’t always get as many clicks as they deserve, so I’m trying to spotlight a few every week.

Fantastic Five shared a great hands on rocks lesson.

Finally, I love the idea of doing a nature study at night like they did over at Angellicscalliwags.
