Introduction: |
|
|
Periodic table is the bible of chemistry. Have you ever wondered
how the periodic table of elements come about? It's development
has interesting story. You don't know that some of them drafted
their own periodic table and imparted their concepts about
it.
The periodic table of the elements is major part of science
and has been used to predict properties of elements that hadn't
been discovered yet. It organizes the elements into different
families based on their properties. During this web quest,
pretend that you are a scientist trying to learn of the history
and importance of the periodic table.
This web quest will enable you trace the development of periodic
table of elements

Task: |
|
|
Working in a group composed of three members,you will search on for the life
and achievements of the scientists who contributed in the
development of periodic table of elements.
Using the provided resources, answer the following questions.
1. Who first attempted to organize the elements into a table
and who came up with the idea of the periodic table that we
use today?
2. How are elements organized into the periodic table?
3. What is the importance of the periodic table?
4. What would science be like if the periodic table had never
been created?
5. What year was the periodic table created?

Conclusion: |
|
|
By making this project, you'll be able to appreciate the
contributions made by the scientist assigned to you. After
reading all of the articles, answer the questions and turn
them in to the teacher.
Include a summary of what you learned about the periodic
table from the web quest and turn it in with the questions.
