A Quest in Chemistry

A Quest in Chemistry
2
Directions for the quest.

• You are going to start an amazing journey through
  the field of chemistry today in class. You will
  have many activities to complete before your
  quest is complete.
• The entire Webquest is located at
  www.jamestownelementary.com located on my
  homepage. This will be the only copy that we will
  use. You can work on the presentation at home or
  at school. You will need to save all of your work
  on your work on a flash drive.
• You will adopt an element, study the chemistry of
  fireworks, and finish the quest with making a
  bouncy ball in class.
• Each activity has a specific set of instructions
  and follow each direction carefully. You will
  need to keep record of all your material as it
  will be used as part of your final presentation.
  Read through the entire quest before you begin.
  Remember, keep all activity materials for your
  final presentation.
• The quest has all the links you need to do your
  research.

Description of each activity

• Adopt an element- This is an activity where you
  chose an element to adopt. You will research the
  element and create a PowerPoint presentation of
  you element. You will be given the criteria for
  your presentation later in the quest. You will
  also answer several questions about the periodic
  table.
• The Chemistry of Fireworks- This activity is
  centered around the chemical bonds involved in
  fireworks. You will use the provided links to
  answer questions about fireworks, then use those
  questions and answers in a paragraph.
• Bouncy Ball- You are going to create a bouncy
  ball in using common household materials. You
  will learn more in-depth about polymers and how
  they are used in the making of bouncy balls.
• Final Presentation- You will need to compose a
  final presentation for you chemistry quest. Keep
  all materials, questions, and answers and put
  them in the order found at the above link.

Your goals for the quest.

• Goals
• You will learn to utilize the Internet to search
  and find information more quickly and efficiently
  and using that information to create a PowerPoint
  presentation about your chosen element.
• You will review your knowledge of the periodic
  table by completing review questions over the
  periodic table.
• You will research the chemistry of fireworks. You
  will research and answer the questions about
  fireworks.
• You will create a bouncy ball in class using
  correct lab procedures and complete a lab report.
• You will compile a final presentation folder over
  all activities in you quest.

History of the Periodic Table

• 1868 a Russian scientist named Dmitry Mendeleyev
  was experimenting with ways
  to arrange the elements, he
  discovered a repetitive pattern to
  several properties, including density,
  metal character, and ability to react with other
  elements.
• Any repeating pattern is called periodic.
• Mendeleyevs periodic table has proved to be very
  successful.

6
History of the Periodic Table cont.

• When Mendeleyevs day only 60 elements were
  known. Today at least 112 elements are known,
  some of them artificial.
• The modern periodic is shown on page E22-E23 in
  your book.

7
How is the table organized?

• The elements are arranged in order of increasing
  atomic number.
• The vertical columns contain elements that react
  with other substances in similar ways.
• Each row of elements in the table is called a
  period. The periods become wider and wider as you
  move down the table.
• The first period has only two elements-hydrogen
  and helium. The sixth and seventh periods have 32
  elements each.
• Elements can be placed in one of three groups-
  metals, metalloids, and nonmetals.

8
Metals, Metalloids, and Nonmetals

• Metals- conduct heat and electricity, are shiny
  when polished, and bend rather than break.
• Nonmetals- do not conduct heat or electricity,
  are dull, and break rather than bend. At room
  temperature nonmetals are mostly gases or brittle
  solids. Are just the opposite of metals.
• Metalloid- any of the elements that have
  properties of both metals and nonmetals and are
  often used as conductors of electricity.

Activity 1

• We are going to start a new activity today in
  class. You are going to create a PowerPoint
  presentation over a given element. You will be
  broken up into groups of to and complete the
  presentation together. The presentation
  guidelines will be on the PowerPoint and I will
  give you a handout. Your presentation will
  include many aspects of the element you have been
  given. Remember to cite your sources for your
  information.

10
Presentation Guidelines

• You will need the following items in your
  presentation. You will also receive a scoring
  guide handout for the presentation.
• Group members names
• Element name
• Atomic number
• Chemical symbol
• Metal, non-metal, or metalloid
• Chemical state (solid, liquid, or gas)
• Characteristics Interesting facts
• At least 10 slides

11
Presentation Guidelines Continued

• Color
• Texture
• Hardness
• Boiling point
• Melting point
• Go to www.sargeantwelch.com to find the price of
  your element per unit
• At least 5 uses of the element. (in detail)
• A minimum of 5 pictures relating to the element.
• Refer to your scoring guide for more details and
  guidelines.

Review Questions

• What information is presented in each box of the
  periodic table?
• Why do you think iron has the chemical symbol
  Fe and not a symbol closer to the English name?
• What do the colors of the chemical symbols mean?
• Why do you think two rows of elements are written
  below the rest of the table?
• Could an element be found in two different places
  in the periodic table? Why or Why not?
• What are the three groups that the elements fall
  into based on their properties?
• What are the properties of each group?

The Chemistry of Fireworks Activity 2

• As part of your chemistry quest you will study a
  very exciting concept in chemistry.
• You are going to research fireworks and how
  chemistry is involved in these colorful
  explosions.
• Click on the following link and follow the
  directions on the webpage.
• You only need to answer the questions about
  fireworks. The paragraph can be completed if you
  want extra credit, but it must be completed in
  you own time and not during class time.
• Link to Fireworks of Chemistry

Bouncy Ball Activity 3

• Your last activity of your quest is making a
  polymer ball, or what everyone calls a bouncy
  ball.
• Just click on the link and follow the directions.
  You will create the bouncy ball and lab report
  individually. The bouncy ball lab will be created
  in class. You will complete the lab in the

  checklist before you begin to compose your final
  presentation folder.

• Polymer lab report
• Your final thoughts of the quest. I need you to
  tell me what you thought of the quest. Be honest
  you will not receive a grade on this portion.
  What parts did you like or not like? How do you
  think it could have been better? What new
  information did you learn from the activities?

Final Results

• On our chemistry quest we have studied the
  periodic table, chemical has showed us how that
  chemistry is present in our everyday lives, even
  if we do not realize it. I hope this quest has
  been fun and exciting and most of all I hope you
  all have learned a little more about chemistry in
  our everyday lives.
