This webquest is designed to allow students to explore the Atomic theory, history and the Periodic Table of Elements. Credit given to Elizabeth Straney for "History Detective Explore the Atom

Introduction

History Detectives

Students will explore the historical development and theory behind the structure of the atom. By examining these theories, the students will also gain a basic understanding of subatomic particles.

Introduction

     

Through this webquest we are going to take a microscopic look at the universal particles that constitute matter.  These particles are found in your cell phone, in the mystery meat from the cafeteria, and even in your own skin and body!  These particles constitute the basic unit of matter:  the ATOM

Today you will explore the history of the atom, learning about its discoverers, its structure, the particles within, and the technology to view it.  Though some of the terms may be new, by the end of the lesson you will have a thorough understanding of the atom!  You will demonstrate this knowledge by writing a paper on each scientist and on a method of viewing atomic structure.

After learning about atoms, you will research the Period Table of Elements and create a final project which will become part of a HUGE period table of elements. 

For many years scientists searched for a way to organize the known elements of the universe onto a useful chart or table.  It was not until the mid-1800s that a Russian chemist by the name of Dmitri Mendeleev recognized hidden patterns that could be used to organize the elements. 

     Mendeleev wrote down many of the known properties of each element on small pieces of paper.  By arranging the elements in order of their atomic mass he began to see patterns emerge.  Although today's Periodic Table is different from Mendeleev's, his Periodic Table became the first useful system for the classification of the elements.

Each element on the Periodic Table has its own unique physical and chemical  properties.  Some of the elements have important uses.  Some were discovered a long time ago and some are man-made. 

     The Periodic Table of Elements is an important resource for scientists.  It provides a wide range of information about the elements.  In this WebQuest you will learn about one of these elements.  You will also learn how that it fits into the arrangement of elements on the Periodic Table.
