Experiment: 1) Take a penny and drop it into the boiling sodium hydroxide and zinc mixture. In order for water to flow more easily into these small spaces, you need to decrease its surface tension. For example, test to see which liquid is the densest, and test the volumes of the drops of each liquid. Students are then given an Overview Is there a way to tell a good year of growth versus a bad year? It is commonly, and mistakenly, referred to as an "educated guess." How big does the drop on the penny get before it finally spills over the edges? There is always a chance that new evidence will come to light in the future to disprove a hypothesis. I hope your kiddos enjoy it as much as mine did! Young scholars perform an experiment that demonstrates acid rain. You have probably noticed that, if you look at a surface outside on a rainy day, or spill some water inside, it tends to form droplets that stick up from a surface, instead of spreading out into an even sheet. It is especially important to realize that middle school students are not likely to have prior knowledge of hydrogen bonding, cohesion, or surface tension, and so are not likely to get the "right" answer for their hypotheses. Your dull pennies should either be green or polished! The salt and acetic acid in vinegar do the trick.
