Description

Overview:
Students work in groups of 2 to create an anchor out of a collection of materials provided by the teacher. Students will test their anchors in an aquarium periodically to determine if their anchor has too much surface area, thus making it buoyant, or if the materials are combined in a way that is denser than the water causing the anchor to sink. The ultimate goal is to balance the forces being applied to the boat.  The anchor is attached to a 3d printed boat, or a boat of the teacher's choosing. A fan is directed at the boat after the anchor has been attached and dropped in the water. In addition to the wind, the teacher will create waves by tapping the side of the tank. Students will observe if the anchor holds under these circumstances or not. Ultimately, they will try to prevent the boat from moving at all. Distance traveled for each test will be taken by a meter stick or tape measure fixed to the side of the tank. Students will strive to keep the boat frozen at 0 centimeters.
