How to build a jet engine from straws
Description
Learn how to build a simple model of a jet engine based on the laws of physics using common drinking straws and a balloon. This experiment demonstrates Newton's Third Law of Motion—the law of action and reaction—showing how a stream of air expelled in one direction generates the thrust necessary to propel an object in the opposite direction.

איך לבנות מנוע סילון מקשיות
למדו כיצד לבנות דגם פשוט של מנוע סילון המבוסס על חוקי הפיזיקה באמצעות קשיות שתייה ובלון. הניסוי מדגים את החוק השלישי של ניוטון – חוק הפעולה והתגובה – ומראה איך זרם אוויר הנפלט בכיוון אחד מסוגל לייצר דחף שמניע את הגוף בכיוון הנגדי.

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
