Activity 2
In this activity you will be using a computer program called Winfeed to find fractal dimensions of lungs.
Materials/Resources:
Computer, Winfeed software, Scanner, pictures of lungs
Directions:
1: Take your students to the science lab in your school or take a field trip to the nearest science lab and take pictures of the lungs of different dissected animals.
2: Help students scan and save the pictures onto a computer.
3: Make sure you have downloaded and installed the Winfeed Software on all computers. The software can be found online for free and it takes just minutes to install.
4: Open Winfeed and click window in the top menu. Click dimension in the drop down menu. A window named noname1 opens at this point. Click File in the top menu then click open and then click external file. A window opens and at this point, you help each student browse to where they saved their pictures.
5: The pictures should show up on the window named noname1. Now, you click Boxes in the top menu and then Box count in the drop down menu.
6: Another window opens with the values of the dimension of the picture.
7: Now you can try it with different pictures of lungs from different animals and compare the values.
