Mixing Oil and Water
Description
Discover why oil and water do not mix and how a connection can be forged between them using bridging agents. This experiment demonstrates the concepts of polarity and hydrophobicity, explaining the role of soap as an emulsifier that breaks down surface tension and allows the two substances to unite into an emulsion.

מערבבים שמן ומים
גלו מדוע שמן ומים אינם מתערבבים זה בזה וכיצד ניתן ליצור קשר ביניהם באמצעות חומרים מגשרים. הניסוי מדגים את המושגים קוטביות (פולאריות) והידרופוביות, ומסביר את התפקיד של סבון כחומר מתחלב המפרק את מתח הפנים ומאפשר לשני החומרים להתאחד לתחליב.

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
