Separating Salt and Pepper
Description
Separating a mixture of salt and pepper becomes a simple task with the help of static electricity. By rubbing a plastic spoon against a woolen cloth, an electrical charge is generated that attracts the lighter pepper flakes, allowing them to be separated from the salt quickly and efficiently. This experiment demonstrates the force of electrical attraction acting on small objects and the principles of static electricity at rest.

איך מפרידים מלח ופלפל?
הפרדת תערובת של מלח ופלפל הופכת למשימה פשוטה בעזרת שימוש בחשמל סטטי. על ידי שפשוף כף פלסטיק בבד צמר, נוצר מטען חשמלי שמושך אליו את גרגירי הפלפל הקלים יותר ומאפשר להפרידם מהמלח במהירות וביעילות. הניסוי מדגים את כוח המשיכה החשמלי הפועל על גופים קטנים ומטען חשמלי במנוחה.

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
