Periodic table of elements

Introduction

You will delve deep into periodic table. You will go back in time to understand the history behind it. Then you will understand what the symbols and numbers on the periodic table mean. Finally you will apply what you have learned to create your own periodic table!!

Task

Use the resources provided to you; read the articles, watch the videos and gain better understanding of the periodic table. Learn to determine the number of electrons, protons, and neutrons of at least 20 elements of the periodic table. Then create your own periodic table!

Process

Break up into groups of three and utilize the given websites to answer the following questions. Each person in the group will be assigned to one of the following tasks: recorder (record the answers to the questions, technical expert (navigate to the websites using the computer), and communicator (the person who asks questions of the teacher and other groups and will also be responsible for presenting information to the whole class).

1. Understanding where the periodic Table comes from and why.

2. What are the top 20 elements and their corresponding symbol and atomic number?

3. Determine the number of protons, neutrons, and electrons for the first 20 elements.

 5. After answering the questions above, you now need to demonstrate your understanding of the arrangement of the periodic table of elements by creating a new table based on properties and characteristics of objects. Follow the instructions below to complete this project.

Objective: You and your group members will come up with your own periodic table of elements. The real periodic table that we study is an organized way of categorizing the elements based on certain properties (mass, metallic character, etc), so for this project you will do the same thing, except now you choose what your ‘elements’ are and how you are going to organize them and how you are going to teach us about your elements.

Instructions:

  1. Choose ‘elements’ that can be categorized

  2. Decide how to categorize them and research them

  3. Organize the ‘elements’ vertically and horizontally

  4. 20 elements is the minimum

  5. Required information: a chemical symbol, a name, atomic mass, and atomic

    number, and at least one other piece of information (electron shells, picture, etc.)

  6. Points will be given for: creativity of table, neatness, logical organization, and is

    all the required information given, and is the project turned in on time

  7. Have fun!!!!

Evaluation
Rubric
# Not acceptable Acceptable Good Exemplary Score
Questions Not complete or all incorrect answers. Work was attempted to be completed and 3 out of the four questions are answered correctly. All of the questions are answered correctly and performed at expected level. All of the questions are answered correctly and the group did beyond what was expected. 25
# of elements Does not include all 20 elements. Includes 20 elements but is lacking in creativity and specific information. Includes 20 elements and specific information for the elements. Uses extensive creativity to represent the 20 elements and represents all of the necessary information about those elements. 40
Group work The students did not work together well and/or only one member of the group did the work. Students worked together without problems and all participated in the required activities. The students worked together well and all contributed a equal amount. The group also stayed on task. The students worked together well and all contributed a equal amount above and beyond what was expected. The group also stayed on task. 25
Spelling and Grammar Major and/or minor grammar errors. Numerous words are misspelled. There are very few grammar and spelling errors either major or minor. There are very few minor grammar and spelling errors, and no major grammar or spelling errors. There are no major or minor grammar or spelling errors. 10

 

Conclusion

After completing the questions in this WebQuest you should have a good understanding and knowledge about what the Periodic Table of Elements is, who created it, the type of information that can be determined by the Periodic Table, and be able to match the first 20 elements of the Periodic Table to their symbols.
