Extracting Sea Salt: A Home Science Experiment filmed during Lockdown
Description
The process of extracting salt from seawater is a fascinating way to learn about solutions, concentrations, and changes in states of matter. This experiment can be easily performed in a home kitchen through boiling, which separates the water from the salt and demonstrates how natural resources are transformed into everyday consumer products. The final result is the white salt crystals that remain in the vessel once the liquid has completely evaporated.

הפקת מלח ים: ניסוי מדעי שאפשר לעשות בבית, שצולם בזמן הסגר
תהליך הפקת מלח ממי ים הוא דרך מרתקת ללמוד על תמיסות, ריכוזים ושינוי מצבי צבירה. את הניסוי אפשר לבצע בקלות במטבח הביתי באמצעות הרתחה המפרידה בין המים למלח, ומדגימה כיצד משאבי טבע הופכים למוצרי צריכה יומיומיים. התוצר הסופי הוא גבישי מלח לבנים שנשארים בכלי לאחר אידוי מלא של הנוזלים.

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
