We have been looking at the properties and characteristics of water. Last week in Science we focused on the surface tension of water. Students put drops of water on pennies and observed how the water formed a dome shape on the penny. The ability of the water to hold itself together on the surface of the penny was surface tension. We now will be looking at how different temperatures of water have different densities. We will complete an experiment that demonstrates this characteristic of water, for the students to see.
