In our very short week back from winter vacation, students participated in a science demonstration to mix a solid with a liquid. We used 4 out of our 5 senses to record and observe what we noticed.
First we observed a white chalky tablet. We discovered it was Alka Seltzer.
Next, we observed a clear liquid. We discovered it was plain old tap water.
Third, we dropped the Alka Seltzer tablet into the water and voila, magic!
Students loved looking, listening, touching, and smelling the reaction.
How could you have changed this demonstration? What other solids would dissolve in a liquid?
