This is all you need to do your science homework!
1) The urinary system (you have to draw it on your notebook)
2) The Quiz (you have to make it 100% correct in 15 seconds or less, and send me a screenshot to my e-mail, carlos1314@gmail.com )

3) The video (you just have to watch it!)
Have fun! Be happy!
