Science Sunday: Sea Cucumbers

 

Now who here read that title and said “Sea Cucumbers is that a vegetable?”  I admit I did at first when I first read that part.

 

But, they’re really rather fascinating.  There are two different kinds.  One that just eats sand and filters its food out of it.  The other has large numbers of tentacles and uses the tentacles to bring the food to its mouth.

 

Well after reading all about this we decided to make our own models, but first we needed play dough.

That accomplished we got busy making our sea cucumbers, I gave them the play dough, tooth picks, and pipe cleaners.

It was quite a lot of work, much hard work.  You know the type of work that they complain when you say it’s time to stop.

Horribly hard work.  They really hated this science lesson.

 

Let’s see what others did this week:

By His Design 5 shared about dissecting owl pellets.  She includes a link for where she got hers.  Last time I did this it was artificial owl pellets.
