STEM Event - Density

September 12, 2025

Students were introduced to the concept of density through demonstration and observation.

For the first demonstration a clear plastic tank was filled with colored fluids of different densities.  Corn syrup on bottom, then dish soap, water, and vegetable oil on top were used.  Students then dropped objects (marble, dry bean, tomato, plastic toy, nerf ball) into the tank.

Students were also introduced to the mathematics of density and performed a second hands-on demonstration, involving adding salt to water until a golf ball floated.
