Students roll dice in order to simulate the probability of locating an electron in a certain region around the nucleus.

In this chemistry worksheet, students complete the table for each element by writing the electron configuration of the element and giving the values of the four quantum numbers. They also create an energy level diagram for their element...

In this atoms activity, 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 and ions.

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.

In this bonding instructional activity, high schoolers take an interactive quiz with 15 multiple choice questions about the VSEPR Theory, bonding, the geometry of molecules, Lewis structures, resonance structures and enthalpy changes.

In this main group worksheet, students apply their knowledge of the organization of the periodic table to correctly answer 30 multiple choice questions. Students relate information about the properties of the different groups and their...

In this molecules activity, students review the parts of an atom and use element mass to determine isotopes. Students give the group, period, and classification for the given elements. This activity has 6 short answer questions and 17...

In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.

In this Bohr model instructional activity, learners draw 16 diagrams given atoms in the periodic table and must show the energy level diagrams indicating the electrons in each energy level.

In this naming and writing chemical formulas worksheet, students are given directions and practice writing simple chemical formulas. They identify positive and negative valence elements, they name nonmetal compounds, they name compounds...

In this charge and electricity worksheet, students read about electric charges and how they are created in atoms. They also read about the unit of charge, called the Coulomb, conductors, and insulators. Emerging electricians match 11...

In a well-prepared Jeopardy-style game, your chemisty class can review the periodic table. Questions cover the element groups, some history, atomic number, atomic and ionic radii, electronegativity, and the shielding effect. What a fun...

Students examine the concepts of isotopes and atoms.  In this powerpoint lesson, students see the balance in numbers  of protons, neutrons, and electrons create isotopes and ions of certain atoms.

Students research and define an atom using a concept map. They design and create a model of an atom, labelling all the parts, and write a journal entry.

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...

Basically walk your early electronics techs through the vocabulary relating to an electronic circuit. Give them an LED light, a resistor, a battery, and some clips, then have them construct a simple circuit. Specific electronic equipment...

In this atom worksheet, learners 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.

What does it look like when two atoms bond? Mol-e-COOL! Aspiring chemists observe the interaction between two atoms forming a bond in an easy-to-use interactive. Individuals move atoms closer together and observe changes in attraction...

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...

Students are often confused by the huge amount of information and detail that can be learned about respiration.  This is a great presentation summarizing the main 4 stages of cellular respiration. It is clear and uses diagrams and...

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the...

What makes helium so Noble, anyway? Explore the bonding properties of helium versus those of hydrogen using an interactive resource. Science scholars manipulate atoms of each element and observe changes in potential energy as the atoms...

Everything is made up of atoms, but what are atoms made up of? The simulation explores subatomic particles. It focuses on hadron, boson, and lepton groupings as scholars learn about quarks, neutrinos, gluons, and more.
