בורג ארכימדס - סדרת פיזיקל - בערכה זו תוכלו להתנסות בבניית משאבה למחזור מים. הכירו את אחת ההמצאות החשובות בעולם.
ערכת מדע לבניית משאבה חשמלית למחזור מים. ההמצאה של ארכימדס, מכונה של שאיבת מים ממקווה מים נמוך, לצורכי השקיה. המצאה זו נחשבת עד היום לאחת ההמצאות החשובות בעולם. לימדו כיצד המים עוברים דרך משאבת הבורג מקצה אחד אל הקצה השני בסיבוב פשוט, בשימוש מזערי באנרגיה ובמעט כוח. לגילי 8+.
