How to Build a Helicopter May 3 2015
Description
Building a simple model helicopter provides a clear look at the physical principles behind flight and lift. This video offers a step-by-step demonstration of how to create a flying craft using only paper and paperclips. You will also see how the angle at which the blades are bent directly affects the direction and speed of its rotation during descent.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
