Station 1

- What do you notice about the flow of liquid throw the model?

- What do you think the pump in the model represents?

-  What wolul happen if we piched one of the tubes in this model? What would happen in the human body if one of the veins or arteries were "pinched"?

- Draw a picture of what you see in this model.


Station 2

- Identify what part of the blood each material is reprsenting in this container.

           The imaginary clear fluid in the conatiner is :

           The red watermelon slices are: 

           The white gumdrops are:

         I make up over half of your body. I am a fluid, and I am yellowish in color. Who am I?

        My job is to carry oxygen and remove waste in your blood. There are about one hundred million of me in each drop of blood. Who am I?


Station 3

- Look at the big jar and read the numbers on the side. The numbers on the side represent how many liters of blood are in our body. Decide how many liters of blood you think we have in our blood. Then take a circular sticker, write your initials, and place the sticker on the jar.

How many liters of blood do you think we have?

- Do you think we need all of our blood in our body all of the time? Explain your answer in complete sentences. If you can think of any examples to support you answer, please include them in your answer.

- Look at the different pipes and wires on the desk. Notice the different sizes of each piece. Each pipe represents a different blood bessel. Please identify each blood vessel by recalling the definitions of each, and write their name on the line.

Gray tube:

Yellow wire:

Red & white wires:

- Make a prediction about what order you think these different blood vessels (wires/tubes) connect to each other.

Station 5

- What are the three things that make up the circulatory system?

- Michelle got a bloody nose in school today. What in her blood made her nose stop bleeding?
