How Remote Controls Work and How to See Infrared Light
Description
Discover how a remote control functions using an LED that transmits infrared signals—light that remains invisible to the human eye. This video demonstrates a simple method for viewing infrared radiation using a smartphone camera and explains the underlying principles of how information is transmitted from the remote to the television receiver.

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
