    This dome-like shape forms due to the water molecules’ cohesive properties, or their tendency to stick to one another. Cohesion refers to the attraction of molecules for other molecules of the. Group Discussion. Explain to students that scientists learn from each All trees and plants have tube-like capillaries called "xylem" walls of plant capillaries, so they rise up in the tubes until they forms a concave shape (like the letter C).
    So it's not surprising that when he observed his first frost flowers, he started experimenting to understand the physical mechanisms behind their formation.
