Electromagnetism 4: Building a Microphone and Speaker
Description
Discover how microphones and speakers operate through the principles of electromagnetism and the fundamental relationship between electric currents and magnets. Through simple demonstrations, we will explore how air vibrations are transformed into electrical signals and vice versa. This process of energy conversion is what ultimately allows us to record and reproduce sound.

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
