Complete the following hands-on activity involving the construction of the traditional unit cells of the simple cubic, body centered cubic, and face centered cubic Bravais lattice types. 1) Please create models of simple cubic, FCC, and BCC crystal structures using a common uniform spherical objects that can be easily cut such as styrofoam balls (available from craft stores such as Michaels or Hobby Lobby or even round fruit. You can use toothpicks or low temperature hot glue to hold the parts together. For each structure (simple cubic, body centered cubic, or face-centered cubic), include a picture of the dismantled unit cell to demonstrate the number of atoms/unit cell and a picture of your unit cell. The corners of all the unit cells should consist of 1/8 spheres. 2) Verify the relationships between the lattice parameter and atomic radii shown in the lecture slides for each unit cell using the table below. Write a conclusion based on your results.
