Cabbage science and the secret of color-changing art
Description
Discover how red cabbage transforms into a natural indicator that changes color when exposed to various substances. Through a simple experiment using cabbage juice, lemon, and soap, we will explore the chemical differences between acids and bases and create vibrant "magic" paintings. The extract produced from the cabbage contains compounds called anthocyanins, which react to changes in pH levels.

למה? ככה! איך מכינים ציורי קסם מכרוב
גלו כיצד כרוב סגול הופך לאינדיקטור טבעי שמשנה את צבעו בחשיפה לחומרים שונים. בעזרת ניסוי פשוט עם מיץ כרוב, לימון וסבון, נלמד על ההבדל הכימי שבין חומצות לבסיסים וניצור ציורי קסם צבעוניים. המיצוי המופק מהכרוב מכיל חומרים בשם אנתוציאנינים המגיבים לשינויי רמת ה-pH.

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
