In at least 3 sentences, describe the forces that moved the floating pieces of chocolate/wax. How did the forces relate to the direction of water flow in the bin?
The forces that moved the floating pieces of chocolate/wax were mainly buoyancy and drag. Buoyancy is an upward force exerted by a fluid (water, in this case) on an object immersed in it. It is caused by the difference in density between the object and the fluid. The direction of the water flow in the bin influenced the direction in which the floating pieces moved. The flow of water provided a drag force on the objects, pushing them along with the current.
