The data may not have been accurate to the real results because of several factors, including human error in calculations, resources used, and etc. I think the main cause for inaccurate data is because of the cardboard we used. The cardboard we used was very thick, and had many different areas which allowed for air to get in. While only around a little of the ship was submerged, the rest was open and the air made the ship less dense than what we calculated. As water flowed through, the ship may have gotten denser, but, overall, the layering may have helped the ship float and hold more mass than what we have originally calculated prior to the experiment. A ship that enables more room for air will mean it is less dense, and that helped drastically in the ships ability to hold more mass. Some other factors that may have caused inaccurate calculations include lack of precision, and wrong calculations mathematically. 

Density and buoyancy are two physical properties that influence how objects behave in fluids, such as water. Density is a measure of the mass of an object per unit of volume, while buoyancy refers to the upward force exerted on an object when it is submerged in a fluid. The buoyancy of an object is determined by its density and the density of the fluid in which it is submerged. When the density of an object is greater than the density of the fluid, the object sinks. If the density of the object is less than the density of the fluid, the object floats. These concepts are important in various fields, including engineering, physics, and marine biology, and are used to understand the behavior of objects in fluids and design structures that can withstand buoyancy forces. In summary, density and buoyancy are related properties that determine whether an object sinks or floats in a fluid, and understanding these properties is crucial in certain fields for designing and understanding the behavior of objects in fluids. 

Density and viscosity are two properties that describe the behavior of fluids. Density refers to the mass of a substance per unit of volume, and viscosity is a measure of how difficult it is for a fluid to flow. Fluids with high viscosity, such as honey, are thick and flow slowly, while fluids with low viscosity, such as water, are thin and flow more easily. Generally, denser fluids tend to have higher viscosities because the particles are packed closer together, resulting in increased forces holding them together and making the fluid more resistant to flow. For example, water has a higher viscosity than gasoline because the particles in water are packed more closely together. When we see density, we are seeing how close particles are compacted. Obviously, the more closely that they are compacted, the more interactions and friction that happens between. Viscosity happens when friction occurs between particles, and this makes a substance more viscous- meaning the more dense a substance is, the more viscous a substance also gets.
