Description:

I know I have mastered the learning targets when

  • watching a glass shatter as it falls on the concrete, I can tell my friend who is laughing at me, why it broke and why the concrete didn't get dented instead.
  • I know that steel is not an element I will find on the periodic table with the other metals.
  • it makes perfect sense to me why a water bug can scoot across a pond and why a raindrop is tear-shaped when it falls from the sky.

Learning Targets:

  • I can describe specific physical properties such as hardness. strength and microstructures of solids.
  • I know what an alloy is and why they are important to our world.
  • I can describe specific physical properties such as cohesion, adhesion and viscosity of liquids.

Reading - Chemistry Connections

Read the article Steel - The Most Useful Alloy.

Do a Google search for steel. Use several variations of words (steel alloy, how do we make steel, steel and Minnesota iron ore, etc.). 

Answer the following questions. These will be turned in with other homework done for this packet.

  1. What is steel in its most basic form?
  2. Why is steel such an important alloy for us?
  3. Name five alloying elements (besides carbon) that can be added to steel, and explain what they do.
  4. Name five places where steel is used in our everyday lives. What alloying elements would you add to steel in each situation to improve its properties?
  5. Give a brief summary of the history of the steel industry in Minnesota.
