One day the Briedis-Ruiz family was on a cruise but the ship crashed in South america. The family had left all of their stuff on the ship including the money they had brought with them so they threw a bottle with a Message in it into the ocean in hopes that a relative or someone would find their message and come to get them. The bottle started it's journey off from South america and it traveled by currents. The bottle first got caught up in the Gulf stream first and traveled towards the Canary current. The bottle then goes downstream of the Canary current towards the South Equatorial current and then goes downstream again from there. When it goes downstream it gets caught up in the Brazil current and once again goes downstream in the Subpolar gyre. The Subpolar Gyre leads the bottle to the west wind drift current up towards the west Australian current. The bottle detaches itself from the current and ends up in Australia.
A family from Australia finds the bottle and reads the message and the message was: "Please help we are stranded somewhere in South America. We have sent this bottle in hopes that someone will find the message inside. Please find us we need help!" The family find a fisherman and ask for his help and the fisherman kindly helps them. The fisherman is currently trying to find out where the Bredis-Ruiz family is. He finds the place where the Bredis-Ruiz family is but wants to make sure so he is trying to find a Route the bottle took. The fisherman finds the right route and explains it to the family who found the bottle "The bottle went from the Gulf stream, to the Canary current, then the South Equatorial current, the Brazil current, the Subpolar Gyre, then the Australian current, and finally towards Australia. But these currents also have differences such as salinity and some currents such as the Gulf stream, the South equatorial current, and the Brazil current have less salinity which means that they have more salt in them. But other currents such as the subpolar gyre, the West wind drift current, and the West Australian current have more salinity." the fisherman said as he finished explaining.
"But why does the Gulf stream, the South equatorial current, and the Brazil current have less salinity?" one of the children asked. "Well that's because there are other differences besides salinity such as temperature and density. The warmer the water the less salinity and density it has and density is the weight, mass, or thickness of something. But if the water is cold then it has more salinity and density because when things get cooled down their Molecules slow down causing them to get closer together and it occupies a smaller volume making the density increase. If something has less density then that means it doesn't have that much mass and isn't that heavy." the fisherman explained.
"What about wind, how are the currents connected to it?" asked the father. "Well as for wind it's connected to ocean currents because wind creates currents. If your wondering how they're connected well it's because the winds go into a certain pattern like if the wind goes right then a current will also go right and now let's find that family." They all set off to find the Bredis - Ruiz family and they eventually did find them. They rescued the Bredis-Ruiz family and they all lived happy lives knowing that they learned something.
