Density of Materials

• Define the density of a material and apply the relevant equation to scenarios where mass is conserved:

$\rho = \frac{m}{V}$

• Utilize the particle model to explain the distinct characteristics of the different states of matter.
• Explain the differences in density between solids, liquids, and gases based on the arrangement of atoms or molecules.
• Draw and interpret simple diagrams that model the structural differences between solids, liquids, and gases.
• Conduct practical investigations to determine the densities of regular and irregular solid objects and liquids.
• Calculate the volume of regularly shaped objects through dimensional measurements and use displacement techniques to find the volume of irregularly shaped objects.
