Sun Magnifying Glass and Welder’s Glass: A Lockdown Science Experiment
Description
In this experiment, we examine what happens when solar radiation is concentrated through a magnifying glass onto ultra-dark welding glass. Discover how the intensified energy absorption of the dark glass leads to rapid, extreme heating, reaching the material's breaking point. Using simple equipment, this demonstration illustrates fundamental physical phenomena, including light concentration, energy transfer, and thermodynamics.

שמש, זכוכית מגדלת וזכוכית רתכים - ניסוי מדעי ביתי שצולם בזמן הסגר
בניסוי זה נבחן מה קורה כאשר מרכזים את קרינת השמש באמצעות זכוכית מגדלת על גבי זכוכית רתכים כהה במיוחד. גלו כיצד בליעת האנרגיה המוגברת של הזجاج הכהה גורמת לחימום מהיר וקיצוני עד לנקודת השבר של החומר. המחישו בעזרת ציוד פשוט תופעות פיזיקליות של ריכוז אור, העברת אנרגיה ותרמודינמיקה.

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
