In a large open building, there were tables with dozens of science / physics experiments, each one with an informational card describing how it worked. It wasn't always easy to see the experiments with so many excited kids around the tables. Over the course of the morning outing, Sierra School students had the opportunity to totally engage with the super interesting experiments. Our assignment was to choose the experiment that we found most interesting and explain its function and interest. Here are two of the experiments that interested us: The Sinking Soda Can presented a container of water in which held two full unopened soda cans. One sunk to the bottom and the other remain floating.

The Sierra School of Todos Santos students and teachers enjoyed a field trip to The University of Colorado campus in Todos Santos (BCS, Mexico), for a physics workshop, "The Little Shop of Physics" prepared by the professors and students of the university in effort to share with students in our town. Students from the public secondary school, and Escuela Pacifica were there at the same time.
The card of explanation read: The difference is that when you dissolve sugar in water, it doesn't really change the volume but increases the mass, which, in turn, increases the density. In this way, soda with sugar is denser than water; and it sinks. Diet soda, with no sugar, floats.
Another experiment was called: Touch a Cloud. This featured a shallow open dish in which water vapor was constantly produced. The descriptive card read: a cloud is made up of small water droplets plus a good deal of water vapor. When the vapor touches your skin, it condenses into liquid, giving up energy and making your hand feel warmer. When you pull your hand back out, the water begins to evaporate taking energy out of your hand and making it feel colder.
The "Little Shop of Physics" was a super interesting,engaging and meaningful field trip for the Sierra School of Todos Santos students and teachers. Everyone had a fabulous time learning about the laws of physics! Thank you CSU for supporting learning in Todos Santos!
