Heart vALVE design
For this project we had to use what we have learned in previous lessons and activities to research and choose materials for our model heart valves and test those materials to compare their properties to known properties of real heart valve tissues. We built a prototype and then built a final model. My group's model is pictured below.
squeeze the purple bottle and water from on the top of the tube there is a flap which the purpose of the balloon is to create
the ice bottle is pulled up through the tube is closed when fluid flows through and pressure so the fluid can be pulled up
open when fluid is not flowing through through the straw (valve)

Reflection: Our model worked well. When we squeezed the bottle on top (the heart), water was pulled up through the tube. We used materials that we already had to build the model such as plastic tubing which is strong like a heart valve. I knew a little about hearts because of classes I've taken in the past, but doing this project and doing research on heart valves helped me learn more about how hearts function. This project was a little bit frustrating mainly because we had to do all of the research and learn how to calculate Young's Modulus on our own. Although it was a bit difficult, my group and I were patient, worked well together, and found good materials, making it so our model was successful.
