How to make a paper football without glue
Description
A hands-on scientific craft activity that demonstrates how to construct a three-dimensional soccer ball using nothing but paper folding and interlocking modular units. The process reveals the sphere's intricate geometric structure—composed of pentagons and hexagons—while teaching principles of structural integrity achieved entirely without the use of adhesives.

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
