Eighth graders act out the role of atoms by dressing up as the atoms of designated elements. They explain the difference between an atom and an ion and explain the role of valence electrons.
Using a chart of student test grades as an example, curious chemists learn how to calculate weighted averages. They apply this knowledge to elements on the periodic table. As practice in calculating average atomic masses, learners evaluate neon and chlorine. This is a clever way to introduce atomic mass that your class will be certain to remember.
High schoolers investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their results to Rutherford's experiment. High schoolers discuss the subatomic particles of the atom and using a handout of the periodic table they construct a model of a magnesium atom using toothpicks and gumdrops.
Students view a PowerPoint to explore the atom.  In this atom lesson, students are introduced to parts of the atom and atom theory. Students sing a song to the Addam's Family theme song.
Students describe the structure of atoms, including the particles that make them up. They recognize that key scientists and experiments have contributed to the changes in the Atomic Theory.
Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain ions, and determine the number of valence electrons for various elements. This is a well-rounded unit test for the very early high school chemistry learner, or even for middle school physical scientists.
In this atoms worksheet, students complete 58 questions about the atomic radius of atoms, the ionization energy, the valence electrons, metals, non-metals and semi-metals and the families of elements.
In this atomic structure activity, students read a story with characters acting as the particles in an atom. They create a trading card for each particle, draw the structure of an atom and sing an atom song.
In this atom worksheet, high schoolers answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.
Students identify and describe electron orbits. In this atom lesson, students make and analyze models of atoms, elements, molecules and compounds. Students view a PowerPoint presentation and discuss the vocabulary.
Eighth graders complete several centers in which they design a brochure on an element, create an elemental trading card and complete a timeline of the development of an atom.  In this element lesson students work together in teams to complete these tasks.
There is something magical about atomic weight. Let learners in your class use a graphing calculator to solve systems of equations related to atomic weight. They use matrix equations and inverse operations to create matrices that describe given compounds.
Students explore concepts of atoms and molecular bonding. In this molecular bonding lesson, students write balance chemical equations to describe elements that tend to bond together. This lesson includes several activities, extensions, and assessment.
Atomic theory, a periodic table, and a place to practice making atom models without having to draw every proton, neutron, electron, and orbital! This resource is colorful, visually pleasing, and easy to use. 
Everything is made of Atoms and the number of electrons and neutrons an atom has determine what form it will take. This class dresses up as the components of an atom to demonstrate the Atomic Model. Great for kinesthetic and visual learners, not to watch but to do.
This old but charming video is part of a longer film. It is not practical for teaching about atomic particles, but it can be used to explore the history of atomic theory. There are interactive quizzes about atomic particles on the website, but you will need to do more teaching on the subject in order to use them.
Drawings on an interactive whiteboard are used to introduce the basic structure of an atom. Technically, the model drawn is inaccurate, as three electrons are shown on the innermost orbital. Electron orbitals are not the intent of the lesson, therefore this is a sufficient explanation of the general structure, especially for younger scientists.
Consisting entirely of photos and simple graphics, this fundamental video is an informative presentation. Topics include elements, molecules, chemical bonds, atomic mass, isotopes, and ionization. Because it covers a wide range, it would be best used as a review for an introductory chemistry unit.
Part of a longer video created by Disney, this segment opens with a history of the telescope and microscope. This old-fashioned video is a sufficient introduction to the topic of atoms. The animations are antiquated, but they are still practical for explaining molecular motion. Strangely, the questions in the associated quizzes cannot be answered by information presented in the video.
Through three separate exercises, chemistry explorers examine common atoms, the periodic table, and atomic structure. They identify the structural features of an atom, read the periodic table of elements, and calculate the atomic weight of an atom, given its atomic number. Plenty of background information is provided. The easiest way to use this resource would be to get learners online to read it and write their answers on a separate piece of paper to turn in.
