Water striders can walk across the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?
The square shapes of the mesh do not fit water drops. The surface tension of the water holds the water molecules together. It has a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. The molecule has two poles, one that is colder than the other.
Water striders (also called water bugs, pond skippers, etc.) are insects that can hop around on the surface of water (Figure 1). Unlike boats or other floating objects that are partially submerged and held up by the resulting buoyant force, water striders are held up by surface tension.
1 wrz 2018 · Students gather data, create a bar graph, and then draw conclusions. They make a CLAIM about how soap affects the surface tension of water and how that would affect the insect. Students then include EVIDENCE for that claim by referencing the number of drops and the lowering of surface tension.
