A video lesson exploring the levels of organization in a living organism from smallest to largest. Learn the smaller particles that make up an organism. [1:58]
Explains the basics of atomic structure, from simple definitions to information about quantum theory. Accurate and helpful basics whether or not you need the more advanced information.
In this interactive activity from ChemThink, students will take a closer look at atomic structure, properties, and behaviors. Includes background reading material and discussion questions. [This resource is available on PBS Learning Media. Free registration is required.]

Check your understanding of how to use the atomic number and the mass number to represent different isotopes. [9:43]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Take a look at the parts of an atom and learn about its properties.
Video tutorial explains the difference between atomic weight and atomic mass in chemistry, and how it compares to the physics definitions of weight and mass. [8:53]

Watch this video lesson introducing the atom, and learn about its unique structure. [3:58]
This video segment adapted from A Science Odyssey takes a look at the scale of the atom and the tremendous amount of space between the electrons and the nucleus. If all this empty space exists in matter, how can any substance be solid? [1:15]
Both of these lessons are classroom activities that require students to build models that display understanding of atoms and molecules. One lesson is structured while the other is guided.
Chemistry is the study of matter, and all matter is made up of atoms. We will learn about elements, atomic number and mass, isotopes, moles (chemistry moles, not the animal), and compounds.

Examine the composition of matter.
A free CK-12 account is required to view all materials.
Visit this site for an interactive tour of the atom and all aspects of particle physics. View the animations available with almost every description on this site. A great place for the fundamentals of particles and forces including a fine glossary. Shows how scientists? views of the fundamentals have changed over time. Wow!
This site resource offers tutorials on the gas laws, balancing chemical equations, and quantum mechanics.
A video investigating the makeup of an atom. Learn that atoms are composed of protons, neutrons, and electrons. Understand that protons and neutrons determine the mass of an atom. Also, the atomic number gives you the number of protons in the nucleus. [21:05]

Mr. Andersen describes atomic structure and tours the periodic table. [9:15]
This activity is a hands-on building of atoms of elements 1-20.
CK-12 Physical Science Concepts covers the study of physical science for middle school students. The 5 chapters provide an introduction to physical science, matter, states of matter, chemical interactions and bonds, chemical reactions, motion and forces, and the types and characteristics of energy.
