Science Project: Relative Density
How to Analyze Relative Density Data and Write a Conclusion Research: The data being analyzed below is about relative density and buoyancy. Relative density is a comparison of densities. Buoyancy refers to something floating in a fluid (gas or liquid). In the diagram, the Box-shaped boats are all floating in water. This means that each […]

The dog has long pink hair. Having long hair is a phenotype, but the pink coloring is a dye. The dog’s natural hair color is white. All phenotypes are inherited and […]
Motion: Speed, Velocity, Acceleration
Science TEKS 8.6B: What is the Difference Between Speed, Acceleration and velocity? Speed is: how fast or how slow an object is moving a scalar quantity, which is a magnitude measurement only measured in distance per time, such as miles per hour (MPH; mi/hr), or kilometers per hour (Km/h) A speedometer indicates how fast or […]
