 Teaching Principles of Biomaterials to Undergraduate Students During the COVID-19 Pandemic with At-Home Inquiry-Based Learning Laboratory Experiments

  1. Select all of the below which best describe the process of corrosion
    1. Chemical
    2. Mechanical
    3. Optical
    4. Electrochemical
    5. Thermal
    6. Magnetic

 

  1. Metals corrode when placed in the body
    1. Always
    2. Sometimes
    3. Never

 

  1. Metals that are passivated protect against corrosion by:
    1. Making the bulk material more crystalline and thus harder
    2. Incorporating inert metals throughout the material
    3. Introducing wanted defects that make the material more ductile
    4. Forming a surface layer that prevents the transport of ions or electrons

 

  1. From the following choices, which best completes the sentence. The fatigue failure rate of metals will increase the most____
    1. If placed in a low salt solution (2 wt%) for a month
    2. If placed in a saturated salt solution (26 wt%) for a month
    3. If placed in tap water for a month

 

  1. From the following choices, which best completes the sentence. The fatigue failure rate of metals will increase the most____
    1. If placed in a basic solution for a month
    2. If placed in an acidic solution for a month
    3. If placed in a neutral solution for a month

 

  1. A metallic hip implant will experience the most corrosion:
    1. Over the entire surface
    2. Where the implant stem meets the ball
    3. In areas that have had surface treatments to roughen them for osseointegration
    4. From scratches caused by the force used by surgeons during implantation
