Sugar In Water

Published on December 27, 2022 by

In this video, students will get to know how understanding particles can help us explore phenomena, such as dissolution of sugar in water. When particles of sugar are added to particles of water, as soon as the sugar hits water, it breaks into individual particles. Upon stirring, these particles spread throughout the mixture. But how does the sugar disappear after stirring? Well, the sugar particles are now filling up the empty spaces between water particles. The reason why we don’t see these sugar particles is because these particles are very small.

This video satisfies the 5-PS1-2 requirement of fifth-grade science proficiency.

Students who demonstrate understanding can:  5-PS1-2. Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
