Describe the forces that moved the floating pieces of chocolate (or wax)
during Part 2 of the activity. How did the forces relate to the direction of
water flow in the bin?
During Part 2 of the activity, the floating pieces of chocolate or wax were moved by the forces of water currents or water flow in the bin. The direction of the water flow determined the direction in which the chocolate or wax pieces were moved.
When water flowed in a certain direction, it created a current that exerted a force on the floating pieces. This force caused the pieces to move in the same direction as the water flow. The strength of the force depended on the speed and intensity of the water flow. A stronger water flow resulted in a stronger force, causing the pieces to move more vigorously.
In terms of the direction of water flow, if the water flow was from left to right, the floating pieces of chocolate or wax would also be moved from left to right. Similarly, if the water flow was from right to left, the pieces would be moved in the opposite direction.
Overall, the forces acting on the floating pieces were generated by the water flow in the bin, and the direction of these forces determined the direction in which the pieces moved.
