Informative Speech On Water Strider

156 Words1 Page

In today’s world, science can find explanations for natural events. Bugs walking on water, too, has an explanation supported by science. The bug that I will inform you about is a water strider. A water strider is a bug that quickly moves through the surface film of water. It also catches prey by using its front legs. A water strider can walk on water due to cohesion. Cohesion is the attraction between molecules of the same substance. To sum it up, cohesion pulls the water molecules together. This pull is the cause of surface tension. The water strider is small enough to be supported by surface tension. Water molecules bond with other water molecules around them. A water strider’s feet can impair the surface, but can not physically break through

    Our hypothesis was partially correct, the property changing substances did have the weakest coherency with the lowest drop counts of 23(carbonated), and 14(soap), and pure water did have the strongest bond. What we also found was the the salt also dampened the liquid’s ability to hold onto a penny in large volumes, as all the different salts had a drop average of 24(28x2 & 16), five less than Tap water’s drop count (30). This led us to conclude that pure water has the strongest bond and that all foreign materials weaken the coherency of water. This evidence has led me to believe that similar substances are attracted and are more coherent towards themselves, in this case the water pieces get separated and generally less connected on a really small level due to the obstruction of foreign objects, this is why the different salts perform better than the huge air bubbles or the slippery properties of soap since the latter is more obstructive and the former dissolves with the water and blocks less. When studying a few other groups’ conclusions and data we did indeed find differences: some groups had differing data where a solution had better coherence than water itself which led to differing conclusions.
