The Milky Way
Description
The Milky Way galaxy is home to our solar system and billions of other stars, all held together by the force of gravity. It is shaped like a vast spiral disk with a densely populated core, which we observe from our vantage point within one of its outer arms. A glance at the sky on a dark night reveals the galaxy’s misty, white band of light—the very feature that gave rise to its mythological name.
Original title
שביל החלב (2010-05-03)
גלקסיית שביל החלב היא הבית של מערכת השמש ושל מיליארדי כוכבים נוספים המוחזקים יחד על ידי כוח הכבידה. היא מעוצבת כדיסקה ספירלית רחבת ידיים שמרכזה מיושב בצפיפות, ואנו צופים בה מתוך אחת מזרועותיה. מבט אל השמיים בלילה חשוך חושף את פס האור הלבן והמטושטש של הגלקסיה, שנתן לה את שמה המיתולוגי.

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

Floating Paintings
Credit: מכון דוידסון לחינוך מדעיDiscover how to bring your drawings to life using nothing more than a whiteboard, water, and an erasable marker. This experiment demonstrates the unique properties of dry-erase ink, which is insoluble in water and does not adhere strongly to surfaces. This lack of adhesion allows the drawing to detach in one piece and float on the water's surface, powered by the force of buoyancy.4:09

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
