AN INTRODUCTION TO THE PERIODIC TABLE
You have been issued a numbered collection of objects. Your group's task is to take this collection of objects and do the following:
- For each object in the collection make a list of as many properties of that object as you can. Maintain the same sequence of properties for each element of the collection.
- Compare the lists of properties for each of the objects and try, somehow, to find an order or scheme in these properties which would enable you to organize the collection.
- Determine a "periodic table" for these objects by physically arranging the objects according to as many of the recorded properties as possible.
- Describe the organization of your group's "periodic table" in report form. Include the sequence of properties which you used to develop relationships. Be as specific as possible.
- While arranging the objects you may feel that an element in the collection does not appear to belong to the collection. If you can make a good case for its elimination, do so. (If an edible, do not merely consume it‹bad lab practice!)
- You may also feel that there are some gaps in your table. If you would like to describe what type of object should occupy this 'gap', do so. List as many probable properties for this missing object as possible. Include reasons for this prediction as well as a sketch of your proposed object.
When your "periodic table" is complete, take a Polaroid photo of it to be handed in with your report.
Grading will be determined by:
- The number of properties used to construct the table and creativity of design.
- The written justification for the table as presented in the Polaroid photo.
- Justification of predictions for objects to fill gaps.
- Elimination justification, if used.
