How to Make Colors Glow in the Dark
Description
Discover how ordinary colors can be transformed into a vibrant glow under ultraviolet (UV) light using simple household materials. This experiment demonstrates the phenomenon of fluorescence, where substances absorb light at one wavelength and emit it at another, explaining the fascinating science behind the spectacular glow.
Original title
איך לגרום לצבעים לזהור בחושך? (2014-05-03)
גלו כיצד ניתן להפוך צבעים רגילים לזוהרים תחת תאורת אולטרה-סגול (UV) באמצעות שימוש בחומרים ביתיים פשוטים. הניסוי מדגים את תופעת הפלואורסצנציה, שבה חומרים סופגים אור באורך גל אחד ופולטים אותו באורך גל אחר, ומסביר את המדע שמאחורי הזוהר המרהיב.

Daniel Asks: Why Are We Afraid of the Dark
Credit: מכון דוידסון לחינוך מדעיThe fear of the dark is an ancient evolutionary survival mechanism designed to protect us from predators lurking in places we cannot see. Our brains tend to fill in missing visual information with our imagination, which triggers a sense of danger and anxiety in children and adults alike. Understanding the evolutionary roots of this fear helps us confront it in a more rational and calming manner.2:48

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
