• Atoms and Molecules -This lesson introduces students to scientific models. The students will learn how models of the atom have changed as new evidence is gathered. The students will also learn about the current model of the atom. Each student will make a model of an atom of a different element.Grades 6-8.
• Introduction to Chemistry Cookie Lab - Students will learn an introduction to general chemistry. They will be introduced to atoms, atom components, elements, and the periodic table..
• Losing It: Tasty Models 5-8 – Scientific American Frontiers Observe the arrangement of atoms within nutrient molecules to explain their chemical behavior, health attributes and role in weight balance. Construct molecular models that represent substances that play an essential role in nutrition. Grades 3-8.
• Chemical Bonding - This unit (5 lessons) focuses on a review of atomic structure and chemical bonding both of which are instrumental in driving the laws of nature. Chemicals bond because of the mutual attractions for the outermost valence electrons and result in chemical reactions characterized by patterns of change, stability unity and diversity. Students will
  demonstrate a comprehension of ionic, covalent and metallic bonding, outer shell stability and molecular formation and structure. Grade 7.
• NOVA The Elegant Universe: Einstein’s Dream: Particle Puzzle Pieces - Learn about some of the elementary particles in the Standard Model and investigate the “recipes” for constructing a proton and neutron from the quarks described in the Standard Model. Grades 6-12.
• NOVA The Elegant Universe: Einstein’s Dream: Detective Work - Understand how physicists study objects they cannot see and analyze a representation of particle tracks like those created in a bubble chamber. Grades 9-12.
• Atoms and Elements: An Introduction – Nature of Matter: How do tribes comprehend items at the atomic and molecular level? Students draw an atom and gain basic understanding of the vocabulary: atom, molecule, electron, proton, neutron. Grades 9-12.
• Building Mocucles from Atoms – Students explore how atoms interact with each other to form molecules. Observations of both different atoms and different molecule formations be made, and model building as a technique to make these observations. K-8.

Atomic Structure: Atomic Mass

Time: 00:41

Atomic mass is the sum of the masses of the protons and neutrons in an atom.

.

Atomic Structure: Atomic Number

Time: 00:47

The atomic number is the number of protons and electrons in an atom. It determines the identity of an element.

Photosynthesis: Atoms

Time: 00:17

Atoms are made of subatomic particles (protons, neutrons, and electrons) that are used in chemical bonding.

Atomic Structure: Isotopes And Atomic Mass

Time: 02:41

The atomic mass is the number of protons and neutrons in an atom. Isotopes are identified by their element symbol and atomic mass.

Physics: The Structure Of The Atom And Atomic Spectra

Time: 08:43

Thomson’s model of the atom has shortcomings. Rutherford’s gold foil experiment led to the present model of the atom.

Atomic Structure: The Dalton Model Of The Atom

Time: 01:17

Dalton’s theory states that atoms that are indivisible spheres, that all atoms of the same element are identical in shape and mass, and that compounds are formed by the joining of elements in a definite whole number.

Atomic Structure: The Atomic Nucleus And Neutrons

Time: 00:45

The number of neutrons in the nucleus of an atom of a given element can vary. Check out this clip to learn how this variance occurs.

Atomic Structure: The Rutherford Model Of The Atom

Time: 01:57

Rutherford’s gold foil experiment led him to state that the nucleus is a dense, positively-charged central portion of the atom, and that most of the atom’s volume is empty space where the electrons are located.
