Question

2. Density is a property of matter that can be calculated by dividing the mass of the substance
by its volume. Write this as a mathematical equation:

3. Open up the Density simulator and click “Intro.
” The substance that the simulation begins
with is wood, which appears to be in a tank of water. Describe everything you notice about the
wood. (Don’t touch any of the controls just yet.)

2. The mathematical equation for density can be expressed as:
\[ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} \]

3. In the density simulator, when starting with wood in a tank of water, I notice the following about the wood:

- The wood appears to be floating on the surface of the water, indicating that its density is less than that of water.
- The color of the wood is likely a natural brown or light color, resembling typical wood materials.
- The texture of the wood may appear rough or smooth depending on the type of wood represented.
- The wood is shaped in a way that suggests it is a solid piece rather than splintered or broken.
- The water around the wood may display ripples or small waves, likely due to the displacement caused by the wood.
- There may be some air bubbles clinging to the surface of the wood, emphasizing that it is less dense than the surrounding water.

These observations highlight the physical characteristics of the wood and its behavior in the water.
