In this atoms learning exercise, students complete a graphic organizer by writing in the number of electrons, valence electrons, electron configuration, orbital box diagram, probability diagram, and Lewis Dot diagram for the given atoms...

In this masses of atoms worksheet, students complete a chart of 7 isotopes with their isotope symbol, atomic mass, atomic number, and the number of protons, neutrons and electrons. They calculate the average atomic mass of two elements.

Words, words, words! This presentation uses plenty of them to define the atom, outline the history of what we know about atoms, and explain atomic and mass numbers. That's all! Informative, but not interesting, this slide show would be...

Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having students drop a pencil on a sheet of...

In this atom worksheet, students complete a graphic organizer for the structure of the atom. They include the definition of the mass number, the atomic mass, the atomic number, the protons, neutron and electrons.

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

In this atomic weight and ions worksheet, students answer questions about isotopes of atoms and how it relates to atomic weight. They also write out oxidation or reduction reactions for given atoms undergoing loss or gain of electrons.

In this atoms worksheet, students complete a graphic organizer by filling in the number of atoms, number of electron pairs, number of long pairs, bond angle, and molecular shape.

"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

Every type of question is used to query young chemists about atomic structure. A vocabulary list tops the page before fill in the blanks, true/false, and matching questions are listed. This is a neatly formatted and pertinent activity to...

A short paragraph helps explain how covalent bonds are formed, and then your class will complete the Electron/Dot and Structural diagrams for the molecules given.  The valence diagrams will reinforce understanding. This activity...

Fifth graders explore conductors and insulators. For this science lesson, 5th graders act as electrons moving through a wire. Students break into groups representing conductors and insulators and explore how they work with electrons.

If you are willing to sort through this outline and overlook the portions relating to inaccessible videos, you will find a wealth of support for your introductory chemistry unit. Narrative is presented to help you help learners navigate...

Eighth graders discuss atoms and electrons as well as atoic structure. They view atomic structure via the computer. Students watch a demonstration in which the teacher demonstrates glass tubing turning yellow in a Bunsen Burner flame....

Show your chemistry class that there's much more to covalent bonding than sharing electrons! Pupils manipulate atoms of hydrogen, oxygen, and carbon to observe the energy of bond formation using a well-rounded interactive. The resource...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

Lewis acids and bases, Brønsted-Lowry acids and bases, ionization, and more are covered by this chemistry handout. It serves as a review of a specific textbook section, but will also serve as a nice review for any general chemistry...

A three-page, mostly multiple choice quiz that would work great as a pretest/post-test for the topic of cellular respiration. It also includes diagram interpretation and a couple of short-answer written response questions. Depending...

Twelfth graders investigate the proper filling order of electrons in the energy levels of an atom. They practice how to "read" these occupied energy levels as electron configurations and demonstrate their understanding through creative...

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements,...

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

An engaging activity enlightens young chemists in this lesson on atomic structure. They play musical chairs through a series of concentric circles that represent electon orbitals. A laundry basket in the middle holds the protons and...

Do some experimentation with reduction-oxidation! Stoichiometry superstars use a single-replacement reaction to study limiting reactant, theoretical yield, and the reactivity of metals through a lab activity. The teacher's guide includes...

High schoolers investigate the structure of the atom and its composition. In this atom structure instructional activity, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the...
