Build a carbon atom out of up quarks, down quarks, and electrons in this interactive activity from the NOVA Web site.

A development of the atomic molecular theory from the law of multiple proportions and law of definite proportions.

Students view continuous spectra from incandescent and fluorescent lights and line spectra of selected elements. Students relate energy to frequency of light seen in the spectra. The presence of only certain lines in atomic spectra is related to Bohr's model of the atom. In a second experiment, students determine electron energies in the hydrogen atom.

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?

In this hands-on activity, students explore the electrical force that takes place between two objects. Each student builds an electroscope and uses the device to draw conclusions about objects' charge intensity. Students also determine what factors influence electric force.

Starting from atoms, see how many molecules you can build. Collect your molecules and see them in 3D!

Students use a balloon to perform several simple experiments to explore static electricity and charge polarization.

In this book the following topics are addressed: electricity and the atom; the nucleus circuits; fields of force; electromagnetism; capacitance and inductance.

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 engineers incorporate these elements into the design of new products and processes. Acting as computer and animation engineers, students creatively express their new knowledge by creating a superhero character based on of the elements they now know so well.

This lesson plan explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. Students think about how atoms and molecules can influence new technologies developed by engineers.

This course focuses on the fundamentals of structure, energetics, and bonding that underpin materials science. It is the introductory lecture class for sophomore students in Materials Science and Engineering, taken with 3.014 and 3.016 to create a unified introduction to the subject. Topics include: an introduction to thermodynamic functions and laws governing equilibrium properties, relating macroscopic behavior to atomistic and molecular models of materials; the role of electronic bonding in determining the energy, structure, and stability of materials; quantum mechanical descriptions of interacting electrons and atoms; materials phenomena, such as heat capacities, phase transformations, and multiphase equilibria to chemical reactions and magnetism; symmetry properties of molecules and solids; structure of complex, disordered, and amorphous materials; tensors and constraints on physical properties imposed by symmetry; and determination of structure through diffraction. Real-world applications include engineered alloys, electronic and magnetic materials, ionic and network solids, polymers, and biomaterials.

This survey chemistry course is designed to introduce students to the world of chemistry. In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior. We will apply this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter. Upon successful completion of this course, students will be able to: Define the general term 'chemistry.' Distinguish between the physical and chemical properties of matter. Distinguish between mixtures and pure substances. Describe the arrangement of the periodic table. Perform mathematical operations involving significant figures. Convert measurements into scientific notation. Explain the law of conservation of mass, the law of definite composition, and the law of multiple proportions. Summarize the essential points of Dalton's atomic theory. Define the term 'atom.' Describe electron configurations. Draw Lewis structures for molecules. Name ionic and covalent compounds using the rules for nomenclature of inorganic compounds. Explain the relationship between enthalpy change and a reaction's tendency to occur.

In this activity, students make a model of a lithium atom using gumdrops and toothpicks. Using this model, they investigate the makeup of an atom, including its relative size. Students also practice adding and subtracting electrons from an atom and determining the overall charges on atoms.

Students will act out the role of atoms by dressing up as the atoms of designated elements. They will wear costumes with balloons representing valence electrons. The "atoms" will gain or lose valence electrons in order to achieve chemical stability. The students must then identify the charges of the ions formed. Grade 8 curriculum alignment.

This film briefly considers the nature of atoms as an introduction to an educational unit on the health effects of ionizing radiation (radioactivity). Educational concepts include atoms, nucleus, proton, neutron, electron, element, isotope, electrical charges, and ions.

This film examines the process of radioactive decay as part of an educational unit on the health effects of ionizing radiation (radioactivity). Educational concepts include radioisotope, radioactive decay, alpha radiation, beta radiation, gamma radiation, x-radiation, decay chain, and half-life.

This lesson introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that electrons can move between atoms, leaving atoms in a charged state.

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 of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are discussed.

This book addresses the following topics: Relativity, rules of randomness; light as a particle; matter as a wave; the atom.
