For my science project, I am modeling the cardiovascular system to find the affect of a narrowed blood vessel on blood flow rate. My teacher recommends that we change up the experiment a little. I have looked in the "Make It Your Own" section, but nothing seems interesting to me. Do you have any ideas on tests or changes I can do to change my project and possibly make it better, while still staying on the topic of blood flow or the heart, and keeping the same materials or a little bit more.
Thank you.

Re: modeling the cardiovascular system
Hi! It seems like as of now, your project is a demonstration of blood vessel size on blood flow rate. Perhaps to add the "twist" your teacher recommend, maybe you can model some common heart diseases (particularly of the blood vessels) and demonstrate the effect on blood flow rate? Just an idea, please post back if I can help you in any other way!

Re: modeling the cardiovascular system
Hi Skylar,
It sounds like you are planning to do this excellent Science Buddies project: https://www.sciencebuddies.org/science- ... p032.shtml
One idea I have is to see the effect that the liquid itself has on the flow rate, in addition to the radius of the tube. You've heard that "blood is thicker than water," and that is technically true! Blood plasma is based on water (as the solvent), but there are many things floating in the plasma that make up blood. In addition, when you are dehydrated, there is less water in the blood, and the other things (ions, proteins, blood cells) make the blood more viscous. Maybe you could examine the effects of viscosity for this project.
I hope that idea gets you thinking. Please post again (in this same thread) if you have more questions.
Heather
