Photosynthesis (May 3 2010)
Description
The process of photosynthesis enables plants, algae, and certain bacteria to convert light energy into chemical energy available to living organisms. By absorbing sunlight, water, and carbon dioxide, the plant produces sugars that serve as its food source while releasing oxygen into the atmosphere as a byproduct. This is one of the most vital biological processes in nature, forming the very foundation of most food chains on Earth.

פוטוסינתזה (3 במאי 2010)
תהליך הפוטוסינתזה מאפשר לצמחים, אצות וחיידקים מסוימים להמיר את אנרגיית האור לאנרגיה כימית הזמינה ליצורים חיים. באמצעות קליטת אור שמש, מים ופחמן דו-חמצני, הצמח מייצר סוכרים המשמשים לו למאכל ופולט חמצן כתוצר לוואי אל האטמוספרה. זהו אחד התהליכים הביולוגיים החשובים ביותר בטבע, המהווה את הבסיס לרוב שרשראות המזון בכדור הארץ.

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
