​Hello,

We have completed the element presentations. When we get back from break, the students will be taking a quiz based on some of the information presented. Most notably, they should be able to use the periodic table to acquire important information about specific elements. If they paid attention to the presentations, the quiz will be super easy. 

Tomorrow will be a fun day with the students participating in a number of fun activities throughout the day. 

When we return from break, we will begin the Rust Project. More on that to come. 

Due Dates

• Little Prince chapters 4, 3, 5, and 6 to be read by Friday. 
• Element Presentations due on Friday (first thing in the morning).

Here are the specific requirements for the Element Presentations. 

Element Presentation Requirements

Your presentation must contain the following information. How you go about presenting is up to you.

• State the name of the element.
  
• Show the symbol of  the element.
  
• Show an image of the element’s Periodic Table Cell.
  
• State when the element was discovered.
  
• State who discovered the element.
  
• Discuss why the element was given its specific name.
  
• Highlight the Atomic Number and explain what the Atomic Number represents in terms of your assigned element.
  
• Highlight the Atomic Mass and explain what the Atomic Mass represents in terms of your assigned element.
  
• Highlight the Mass Number and explain what the Mass Number represents in terms of your assigned element.
  
• Specify the number of protons in the element.
  
• Specify the number of neutrons in the most common isotope of the element.
  
• Present an image of the Bohr Model of your element’s most common isotope. The image should highlight the number of protons, neutrons and it should show the electron configuration. Two examples of the Bohr Model of a Chlorine atom are shown below.
  
• ​State the phase of the element at room temperature.
• Show several images of the element in the above phase.
  
• State the melting point of the element in fahrenheit.
  
• State the boiling point of the element in fahrenheit.
  
• Report the electrical resistivity of the element in ohms.
  
• Compare the electrical conductivity of your element to copper.
  
• Report the thermal conductivity of the element in watts per meter kelvin (W/(m·K)
  
• Compare the thermal conductivity of your element to copper.
  
• Report on the hardness of your element using the Mohs Hardness Scale.
  
• Compare the hardness of your element to copper.
  
• Describe the strength and toughness of the element (use comparisons if possible). It would be very cool if you could find examples of stress tests.
  
  • Strength: The amount of force necessary for a material to deform. The higher the force required to change the shape of the material, the stronger the material is. Steel is notoriously difficult to pull apart, hence it has a high strength. Silly putty, on the other hand, is not strong at all, and merely requires a child’s touch to quickly deform this material into all sorts of shapes.
    
  • Toughness: How well the material can resist fracturing when force is applied. Toughness requires strength as well as ductility, which allows a material to deform before fracturing. Do you consider silly putty to be tough stuff? Under these terms, believe it or not, it actually is relatively tough, as it can stretch and deform rather than break.
    
• Describe how resistant to corrosion the element is.
  
• Show images of the element in various stages of corrosion.
  
• Report where the element is found.
  
• Show a map that highlights where in the world the element is found.
  
• Describe how the element is extracted or obtained.
  
• If obtained from an ore, show pictures of the ore.
  
• Describe how the element is used and what it is used for.
  
• Show pictures of the element in use.
  
• Discuss if the element is toxic and any other dangers to humans that the element might present.
  

Due Dates

• Little Prince chapters 4, 3, 5, and 6 to be read by Friday. 
• Element Presentations due on Friday (first thing in the morning. 

1st Quarter Assessments should be coming home next Monday or Tuesday. 

We are slowly reorganizing ourselves after the chaos and craziness of the last few weeks. The food show and the camping trip were big successes, but it is now time to turn our attention to new projects and new activities.

We are currently reading The Little Prince. Students have been assigned chapters 4, 3, 5, and 6. These chapters should be read by Friday. The chapters are relatively short, and there are pictures. 

Also, we are doing some introductory work to prepare us for the rust and corrosion project. That project will begin after the break. For now, we are exploring the periodic table and students are creating mini presentations about a specific element. These presentations are due on Friday. Students will have plenty of time during class to research and develop their presentaitons. They should not need to do any work at home (if they use their time well). Students spent today researching their assigned element. They needed to gather the following information. 

• Name of Element
• Symbol
• Atomic Number and Explanation
• Atomic Mass and Explanation
• Mass Number and Explanation
• Number of Protons and Neutrons
• Image of the Elements Periodic Table Cell
• Phase at Room Temperature
• Melting Point
• Boiling Point
• Conductivity of Heat and Electricity
• Strength
• Hardness
• Resistance to Corrosion
• Where Found
• Abundance
• How Extracted
• Uses
• When Discovered
• Who Discovered
• Toxicity
• Dangers
• Please provide supporting images throughout the presentation.
