Investigation: How Does a Water Strider Stay on Top of the Water? Introduction: The water strider can manage to slide along the surface of water while searching for other insects to eat.
27 kwi 2020 · Holes That Do Not Leak!: explore how surface tension can be strong enough to plug a small hole and prevent leaks. Build a Water Strider: experiment to see how the shape of a water strider helps it stay on top of the water's surface. Blowing the Best Bubbles: discover the best recipe for making bubbles.
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.
students around the concepts of surface water tension and introduction to how a water strider floats.

Have you ever seen a water strider (also called water bugs, pond skaters, water skippers etc.)? They are bugs that effortlessly hop around on the surface of ponds, lakes, and rivers. How do they do it without sinking?
1 wrz 2018 · A version of the penny and surface tension lab that includes background about water striders and how they stay on top of the water. Students examine how soap my disrupt the surface tension of water by comparing the number of drops that fit on a penny.
This resource is a quick and easy way to introduce the problem solving process to students in biology. Students add drops of water to a penny and then add soap to the water and repeat the experiment.
