What's inside an animal?

Dear Parents, 

We're working on a unit called Living Things, where we're exploring different things that are alive. Students are working on a shoebox diorama of an animal at home, and at school, we're exploring what we know and what we want to know about these things in general. 

Today, we reviewed the 7 things that all Living Things do
1. Take in food
2. Get rid of waste
3. Move
4. React 
5. Grow
6. Reproduce
7. Breathe

Then I gave students an outline of an animal and asked them to show me how they do those things. Here are the results

One elephant has a tube straight through. The other has bones in its legs, a stomach with food in it and somewhere to excrete waste.

On the left, there's a backbone, a heart, a "tummy tube" and some bones in a complicated geometric arrangement. On the right, there's a brain, a heart, a "pee tube", a "butt tube" and a muscle. 

On the left, the crow has eyes and a heart. On the left, it has blood flowing around the crow. 
"Moves with feet. It grows when it eat good thing. Eat with mouth. Breathe with its gills"

The fish on the left has a heart and eyes and a brain. There are tubes that could indicate gills or circulation or digestion. On the right, there's a brain, eyes and a clear digestive system (the arrow pointing to the stomach is cut off).
There are little fish inside the bigger fish, but I'm not sure whether those are baby fish or things it's eaten. The fish on the right has taken a more descriptive route: "Food makes growth. It moves with its flippers.It gets energy from food. It makes waste by giving bad food."
Both Octopuses have brains and suckers on their tentacles. One has bones and is also giving off waste. 
This camel has lungs, a heart, food in its hump, bones in its legs, and a bum...but no real connection between the parts.

I hope you find their drawings as fascinating as I do. It's always interesting to know how what we know starting out, so we can make connections. 

I also had students ask some big questions they want to know the answers to:

How does a fish move in water?/How do octopus suckers work?/How do rabbits ears work?/ Do animals breathe at different speeds?/Can an elephant's tusk crack?/Can fish tails bend?/How do trees reproduce?/Why do people have toes?


How do plants know to react?/What do muscles look like?/How do elephants have babies? /Does everything reproduce? /How do bones move?/ Do worms see? /Why do flowers have petals?/Does grass ever stop growing? /Can a bird's beak crack?
I love these questions and I look forward to answering them with students over the coming weeks. 

Sincerely,

Ms. Goegan
