The Rubber Band Gun and the Law of Conservation of Energy
Description
Building a simple rubber band gun provides a hands-on demonstration of the law of conservation of energy and the conversion of elastic potential energy into kinetic energy. The stretched rubber band stores energy that is released the moment the trigger is pulled, allowing us to examine the forces at play within the system and the fundamental principles of the physics of motion.

רובה גומיות - וחוק שימור האנרגיה
בניית רובה גומיות פשוטה מאפשרת להדגים בצורה מוחשית את חוק שימור האנרגיה ואת המרתה מאנרגיה פוטנציאלית אלסטית לאנרגיית תנועה. הגומייה הנמתחת אוגרת אנרגיה שמשתחררת ברגע הירייה, וכך אנו לומדים על הכוחות הפועלים במערכת ועל עקרונות הפיזיקה של התנועה.

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
