Students explore the concept of the mole as a measure of quantity. They build spreadsheets that allow them to convert between moles, grams, and atomic mass units for given quantities of everyday items, elements, and simple chemical...

DENSITY is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For...

This module simulates the measurement of the density of a gas sample. Different gaseous compounds and elements are available and the pressure and temperature of the sample can be adjusted.

Type in an element or compound and the temperature and corresponding vapor pressures are shown.

Humphry Davy was a pioneer in the field of electrochemistry who used electrolysis to isolate many elements from the compounds in which they occur naturally. Electrolysis is the process by which an electrolyte is altered or decomposed via...

The ways in which an element or compound such as water moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. All of the atoms that are building blocks of living things are a...

[Free Registration/Login may be required to access all resource tools.] Students will use the physical and chemical properties of matter to categorize the various forms of matter.

Matter is all around us, so it's a good idea to know what it is, and why it matters. Learn about matter, its categories, and its subcategories with this interactive lesson.

This entry focuses on the rules for comma use including listing the uses, explaining the rules, and providing detailed examples.

Find out the basic characteristics and main properties of all matter.

In this activity, students construct models of molecules using marshmallows and gum drops.

[Free Registration/Login Required] Explore the composition of air and learn about the different atoms and molecules that we breathe every day.

Kid's learn about the science of the molecules. Tiny chemistry and compounds of atoms and elements make up all matter.

[Free Registration/Login Required] This flipchart is a guided activity to help students compare different types of matter: atoms and molecules, elements and compounds, mixtures and solutions. It corresponds to Virginia science SOL 5.4.

Discover all the elements and chemical compounds that are found in the air. They are presented in a chart listing their symbols, molecular weights, and what percent of the atmosphere they each comprise. A set of facts is also provided.

The glass bottle is a type of measure. It contains the remains of acid compounds and has a stamp to ensure the drugs or chemical materials were not tampered with.

This reading/lesson plan introduces learners to the concept of organic chemistry.

Through this reading, students will learn that a substance's properties arise from its molecular structure, not from how it's made (i.e., synthesized by people or found in nature). There is no fundamental difference between natural and...

This reading is an introduction to the great variety of steroids and their many different uses.

[Free Registration/Login may be required to access all resource tools.] Describes the significance of carbon to life on Earth.

[Free Registration/Login may be required to access all resource tools.] Covers the significance and functions of carbon.

In this lesson, students are introduced to the 5 major types of chemical reactions. Each reaction type will be analyzed and specific examples will be noted. Students will then perform a lab investigation which includes each of the...

The Discovery Channel provides numerous lesson plans dealing with the physical sciences. Content is organized by grade level, but all lesson plans include suggestions for adaptations for older or younger audiences.

This Homewood City Schools site has an outline form and contains lots of information about the classification and composition of matter. Some of the topics covered are matter and temperature, changes in state, composition of matter, and...
