Exploring the Periodic Table

Introduction

Welcome, young scientists! In this WebQuest, we’ll dive into the fascinating world of chemical elements. Our journey will take us through the Periodic Table, where we’ll uncover patterns, properties, and the secrets of the elements. Get ready to explore!

 

Task

Your mission is to become an element detective! You’ll investigate the structure of the Periodic Table, understand the significance of each group, and discover the properties of specific elements. Your final product will be a creative presentation that showcases your newfound knowledge.

Process

  1. Major Players: Visit this website and learn about the contributions of various scientists to the development of the Periodic Table. Fill in the table with their names and their significant contributions.

    • Greek thinkers
    • Lavoisier
    • John Dalton
    • Doberiner
    • Dechancourtois
    • Cannizaro
    • Newlands
    • Meyer
    • Mendeleyev
    • Moseley
    • Seaborg

  2. Get Organized Periodically: Explore this resource to understand why elements are placed in specific locations on the Periodic Table. Answer the following questions:

    • What are periods? How do they run?
    • What are groups? How do they run?
    • Describe the pattern of electron shells in the first and second periods.
    • Why is hydrogen unique?

  3. Family Fun: Visit this page and click on “Alkali Metals” (left bar). Answer the questions:

    • What is the group number for alkali metals?
    • Are these metals reactive?
    • Do they occur freely in nature?
    • How many electrons are in their outer shell?
    • Describe the characteristics of ALL metals.
    • Are alkali metals soft or hard?
    • Name the two most reactive elements in this group.

  4. Explore other groups such as “Alkaline Earth Metals,” “Transition Metals,” and “Other Metals.” Answer similar questions for each group.

  5. Create Your Own Periodic Table: On a blank sheet, make a diagram that includes:

    • Element symbols
    • Atomic number location
    • Atomic mass location
    • Numbered groups (vertical columns)
Evaluation

You’ll be assessed based on the accuracy of your answers, creativity in your presentation, and your understanding of element properties. Here’s the rubric:

  • A: Exceptional understanding and creativity
  • B: Solid understanding and good creativity
  • C: Adequate understanding and basic creativity
  • D: Limited understanding and minimal creativity
  • F: Incomplete or incorrect responses
Conclusion

Reflect on your journey through the Periodic Table. What surprised you? Which elements fascinated you the most? Share your thoughts in your presentation. Remember, science is all about curiosity and discovery!
