The Flowers of Chemistry
Description
The process of diffusion and material exchange is spectacularly demonstrated through metal salt crystals placed in a sodium silicate solution. As the salts react, they form a semi-permeable membrane that repeatedly swells and bursts, giving rise to vibrant, plant-like or coral-shaped structures known as a "chemical garden.

פרחי הכימיה
תהליך הדיפוזיה וחילופי חומרים מוצגים באופן מרהיב באמצעות גבישי מלחי מתכת המוכנסים לתמיסת נתרן-סיליקט. המלחים מגיבים ליצירת קרום חדיר למחצה שמתנפח ומתפרץ שוב ושוב, מה שיוצר מבנים דמויי צמחים או אלמוגים צבעוניים המכונה ״גן כימי״.

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
