WebYou can use this lab when teaching scientific method (variables), chemistry (surface tension, cohesion), or to reinforce graphing and scientific testing skills. It is fun for students to come up with their own variables and test them as extensions (tap water vs. distilled, dirty penny vs. clean, etc). This lab is editable. Ma Subjects: WebMar 29, 2016 · The first of our experiments is the simplest, and one of the most fascinating for students. Place a penny on a flat surface and record the number of water drops that can be added to the top of the penny …
WebTesting the Properties of Aqueous Activity 3: Koherence Will Cost They one Penny! The surface tension of water is produced by cohesion. Cohesion means that the water molecules like to stick to either other. This is caused by the lighter damaging command of the oxygen atom are one water molecule being attracted toward the slightly positive ... WebUse the language of cohesion, adhesion, polar and nonpolar in relation to each of the liquids. Describe any differences you observed in relation to the surface the liquids were touching. Recall the penny experiment from Activity 2 where you were able to observe the effects of adhesion and cohesion on water’s ability to pile on top of the penny.

WebCohesion is the ability of water molecules to bind together; this experiment ties into cohesion because for the water to stay on the penny, they must bind together. Hypothesis: I believe that about 15 water droplets will fit onto a penny. A droplet of water is rather small and water droplets will bind together. new listings murrietaWebApr 30, 2024 · How many drops of water can you get on a penny? new listings nantucketnew listings my homeWebBIOL 1014 Lab 3 Cohesion of Water Part C: Perform tests with the Alternative Liquid.
