Parking:
Teams will be allowed to unload materials at Sesquicentennial Park along Preston Street between 7:30 and 8:00am in between Smith St. and the bayou. Vehicles will be allowed back after 1:00 p.m. to pick up materials.
Parking can be found underground in front of the Wortham Theatre.
More details on rules and judging criteria coming soon!
What makes something float?
Buoyancy, or the force pushing upward on an object in a fluid, is equal to the weight of the fluid displaced by the object. The relationship between buoyancy and the weight of the displaced fluid is called Archimedes’ Principle.
Objects submerged in fluid appear to weigh less than they do out of the fluid. This is caused when the force at the bottom of an object in a fluid is greater than the force at the top of the object. The overall force is in the upward direction and acts against the downward weight of the object. The upward force is called the buoyant force.
So why do some objects float and some objects sink? The answer lies in the object’s density. Density is the relationship between an object’s volume and its mass. An object will float in a fluid if the density of that object is less than the density of the fluid.
Air also plays a role in whether some objects sink or float. A heavy steel ship is built of a steel shell with a hollow inside. So the volume of the ship is made up mostly of air. The ship and air together have a density that is less than that of water. They can displace a weight of water equal to or greater than their weight. As the boat displaces the water, the water pushes upward against the boat. These forces together cause the boat to stay afloat.
The cargo on a boat also becomes a factor. If a boat is loaded with too much cargo, it will have a higher density and will ride lower in the water because it has to displace more water to stay afloat.
