Monday 23rd-Thursday 26th

1) Solutions to Thursday's exercises (SB p. 76)
2) Solutions to Video:
1. How long is the system?  600 meters  How deep is the skirt? 3 meters
2. Can the cleanup barrier affect marine life? Why? No, because the skirt creates a flow underneath and the marine life can pass beneath it.
3 How does the cleanup system work? 
a. The buoy prevents PLASTIC from FLOWING OVER IT and the skirt prevents SMALLER PARTICLES FROM ESCAPING UNDERNEATH.
b. The system is operated by WIND, CURRENTS, and WAVES.
c. Both plastic and the system are CARRIED by THE CURRENT.4. Why does the system move faster than plastic? What is the result?
BECAUSE THE WIND AND WAVES CAN ONLY PROPEL THE SYSTEM, NOT THE PLASTIC5. How does the system adopt a U-shape? BECAUSE THE CURRENT APPLIES PRESSURE ON THE SKIRT. What is the result? PLASTIC IS CONCENTRATED IN THE CENTER.
6. The WIND helps the system change direction and takes it to THE AREAS WITH THE HIGHEST PLASTIC CONCENTRATION.
7. How is the system's position known?
THANKS TO SATELLITE ANTENNAS.8. How is plastic removed from the system? A VESSELS COMES REGULARLY AND TAKES OUT THE PLASTIC. What do they do with that plastic? THIS PLASTIC IS RECYCLED INTO NEW ITEMS.
9. Opinion: Do you see any disadvantage to this invention? Justify your answer.
