List all of the materials that are in the chair in which you are now sitting. Why are these materials used. Be specific. Why aren’t other materials, such as wood and cloth used?
Some outdoor markers, such as those found in cemeteries, are expected to last for centuries. Based on you knowledge of materials engineering (Lesson 1), why has bronze, historically, been used for this purpose more often than stainless steel? Give at lease 3 reasons.

The types and uses of plastics greatly increased in the early to mid 20th century. How would engineering be different if plastics were not available as a material? Explain your answer.
Many people see scientists and engineers as having distinct job descriptions. Scientists explore, experiment, and discover; engineers create, design, and build. Does this distinction seem clear to you? Or do you see overlap in the functions of scientists and engineers? Explain your answer.
Billionaire tech entrepreneur, Elon Musk (boss at Tesla and SpaceX), called artificial intelligence (AI) more dangerous than nuclear warheads. (1) What does he mean? (2) Explain why you agree or disagree.
Some engineers work in secured areas that are off limit to the public. Explain why you think this is done? Give 2 or 3 examples of situations in which you think this kind of security is necessary. Explain why for each example.
Some people argue it is impossible for individuals to invent or perfect significant new technology in our modern world. For example, Edison (electric light bulb, 1879), or Marconi (radio, 1890’s). Instead, giant corporations or institutions now develop all the significant new technology. Do you agree? Explain your response.
Assume a bridge falls down, or an airplane crashes because of miscalculations in the engineering. Also assuming it was an honest mistake, is it fair to blame the engineer(s) who made the errors? Explain your answer.
Describe a major problem you think engineers will solve in the next 5 or 10 years?
- Why hasn’t this engineering problem be solved in the past?
- What barriers remain in order to solve this problem?
