This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

This page from Especial Gas Inc. contains some very interesting information about the element sulfur, and some of its common compounds. The history and relative abudance of the element is discussed, as well as where it can be found. The...

This hands-on activity will help the students have a better understanding of different types of materials as pure substances and mixtures and distinguishes the homogeneous and heterogeneous mixtures by discussing some material they use...

A video and a short quiz on elements, how they combine through chemical reactions to make compounds, and how to write the chemical formulas for water and salt.

This lesson will present a basic overview of elements and how they interact in chemical reactions and compound formations. It is 2 of 4 in the series titled "Compounds and Elements."

Lots of valuable information on nitrogen, its properties and some of its uses and compounds.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will name ionic compounds containing main group or transition metals, covalent compounds, acids, and bases, using...

Students learn about the periodic table and how pervasive the elements are in our daily lives. After reviewing the table organization and facts about the first 20 elements, they play an element identification game. They also learn that...

Learn how compounds are formed and broken down by chemical forces.

A laboratory experiment where students classify matter into a homogenous mixture, heterogeneous mixture, solution, or pure substance. Also students will test for physical and chemical changes.

Learn about the classification of matter based on whether the chemical composition is pure or a mixture. Understand the definitions of elements, compounds, substances, and mixtures, and what the differences are between them. Five types...

In this lesson the students will learn how to classify the materials as mixtures, elements and compounds and identify the properties of each group. Also the concept of separation of mixtures will be introduced to the students. Since...

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...

Chemical composition is a section of a larger overview on Chemistry, covering a variety of aspects. This section focuses on elements, atoms, compounds, and structure. Examples, formulas, and pictures are provided.

Short slide show provides basic information about drawing Lewis dot structures for covalent compounds. Starts with anatomy of the atom, and then shows the relationship between atomic particles and the Periodic Table of Elements. Offers...

Learn here about organic compounds, groups of carbon atoms covalently bonded to hydrogen, usually oxygen, and often other elements as well, and how they are essential to human functioning.

[Free Registration/Login may be required to access all resource tools.] Students will understand the general properties that distinguish ionic compounds from other substances, and predict which elements are likely to form ionic compounds...

[Free Registration/Login Required] An informational text about how chemicals can be combined to form safe or unsafe compounds. A question sheet is available to help students build skills in reading comprehension.
