#### Storyboard Text

• It was a regular school day when Grace stumbled upon an interesting concept that piqued her interest...
• Grace﻿
• What might that be?!﻿
• ﻿Hello class, today we will be talking about something quiet interesting.
• Geography Class﻿
• ﻿Water Currents An ocean current is a directed movement of ocean water.  The currents are generated from forces like the earth's rotation, wind, temperature, salinity differences, & the gravitation of the moon.
• ﻿Wow! So interesting!
• ﻿Boats going against the water current of the ocean take more time reaching their destination, because of the forces working against them. However, boats going downstream (following the current) will reach their destination faster.
• Grace's Thoughts: So, that means that when the boat is going upstream, the pseed of the current is working against the speed of the boat. So, speed of boat-speed of current. And when the boat is going downstream, the current makes the boat go faster. So, speed of boat+speed of current.﻿
• ﻿Physics Class To find the distance that an object has passed, you must use the equation (speed x time= distance). st=d
• For example, if a boat has traveled 26 miles upstream in 2 hours the equation could be: (speed of boat- speed of current) 2= 26 And if the same boat traveled 56 miles downstream in 3 hours the equation would be: (speed of boat+ speed of current) 3=56
• You can use this formula to find the speed of the boat and the current!﻿
