BACKGROUND: The periodic table can be classified into metals, nonmetals and metalloids. The characteristics of these groups vary greatly; Metals tend to be ductile, malleable, have a metallic luster and are conductors of heat and electricity. Nonmetals tend to non-lustrous, brittle and poor conductors. Metalloids share some characteristics of both metals and nonmetals.

Purpose:
Why do we organize things? What are some different ways that we organize information? How do scientists organize the elements? The periodic table is organized so that elements with common properties are placed near each other or in similar fashion. In this way, we can use the periodic table to predict behaviors of elements with which we are not already familiar.
To examine some elements observe their properties. Using these observations, students will confirm the common properties of metals, nonmetals and metalloids.
Materials:
Assorted metal, nonmetal and metalloid samples, conductivity tester, magnets
Procedure:
- For each sample, write the name and symbol of the element samples
- Describe the physical features of the sample by observation.
- Test each sample for conductivity using the tester device.
- Test each sample for magnetism by passing a magnet over the sample.
- Test the samples for malleability, ductilibility and brittleness by touching the metals and testing them.
- Check the appropriate characteristics for each sample.
- WASH YOUR HANDS after the experiment.
- Answer the questions based on observation, inference and selective testing.
