Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

Fifth graders investigate atoms. In this atom lesson, 5th graders investigate the parts of an atom. Students explore atom numbers and determine the number of electrons is in each atom.

Students write electron configurations and identify groups.  In this investigative lesson students use valence electrons to draw electron dot structures. 

In this chemical bonding activity, students answer 10 questions about ionic bonding, covalent bonding, metallic bonding, Lewis structures, and intermolecular forces.

After a short introduction, chemistry aces get right into drawing electron dot diagrams for covalent bonds. There are only three questions to answer, so this is not a comprehensive worksheet. It can be used when introducing your class to...

Eighth graders practice balancing chemical equations. In this chemistry lesson, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.

This site provides an interactive periodic table of the elements. Select an element for a general description, images, audio files, and movies.

This essay, written for Teachers' Domain, describes the foresight and pattern recognition that Russian chemist Dmitri Mendeleyev used to develop the modern periodic table of elements.

This interactive periodic table developed for Teachers' Domain provides detailed information about the chemical properties of elements and illustrates the electron configurations that determine those characteristics.

A fun way to learn about the periodic table! This interactive table allows students to investigate the basic information of an element as well as explore group and family characteristics.

This site has a periodic table on it. When you click on each element, it brings up information about it. Site is organized, detailed, and helpful for learning.

An interactive introduction of how the periodic table is broken down. Shows basic groupings of the elements.

Read about the addition of four new elements to the periodic table. Includes video.

This page displays the Periodic Table of Elements and allows you to click each individual element for a page that displays in-depth information about that particular element. There are also links to many different games and learning...

An interactive Periodic Table of Elements which also serves as a visual database of each element's physical and thermochemical properties. Online activities include virtual graphing, tables of data, energy level diagrams, games, and more.

An interactive periodic table of elements. Click an element to view a detailed description. Click the flags at the top to choose your language: English, French, Spanish, Dutch, and German.

Students can use this resource to interact with the periodic table. Information is available for each element. This is a good source of information for younger students.

An interactive Periodic Table of the Elements that displays specific properties of each element

Students study trends in the periodic table of elements, supplemented by the use of spreadsheet functions. The spreadsheet functions presented can be used on any data set.

This interactive periodic table provides information about each of the elements. This is a very comprehensive site.

An interactive periodic table of elements allows users to click on elements and discover the details of each one.

Click an element on the Periodic Table of Elements to learn more information such as the history and uses, origin of the name, isotope data, and more essential facts!

In this tutorial, students will investigate the arrangement of the Periodic Table by watching videos, completing interactive activities, and quizzes.

Video explains why the periodic table devised by Dmitri Mendeleev has endured and how it has predicted the existence of elements. [4:25] Followed by a short quiz and a list of additional resources to explore.
