In this activity, students make a Cartesian diver to demonstrate the relationship between volume, mass and density. A similar principle is used in Argo scientific floats....
Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least...
The water cycle happens all around us. Changes in the state of water and the water cycle are driven by the Sun’s energy. There is no...
