Teach your class to think of electrons as tiny packets of energy that travel in waves. Through a short video and diagram, participants see how electrons are located around the nucleus of an atom. They then get into groups and try to...

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

An engaging activity enlightens young chemists in this lesson plan 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...

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.

Students write electron configuration of elements using atomic numbers and they identify valence electrons. For this electrons lesson plan, students observe a demonstration showing the space-filling property of an electron. They also...

Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

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...

Ninth graders investigate ionic bonding through energy level diagrams. In this ion bonding lesson plan, 9th graders observe demonstrations to show energy level diagrams using magnets to represent the subatomic particles. Students fill...

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.

In this atoms worksheet, learners determine the energy difference between levels and draw diagrams of the different types of orbitals. Students determine the ground state electron configuration for given elements. This worksheet has 14...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Using the chemicals that leaked in the Bhopal gas tragedy of 1984, chemists examine covalent bonds. Provide for them the chemical reactions and have them draw Lewis diagrams for the molecules involved. That's about all there is to the...

How are chemical bonds similar and how are they different? Provide your young chemists with the resources to more thoroughly understand the concepts of ionic and covalent bonds. Pupils research these topics, diagram examples of each...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

The fifth lesson plan of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments...

Young scholars write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

Students are introduced to the periodic table. They find the common trends among the electron configurations and the names of certain groups of the table. Students explore the atomic mass, atomic number, mass number, mass and charge...

Young scholars observe the periodic table and draw the Lewis Dot Diagram.  In this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they...

Students investigate the factors that compose the nitrogen cycle. The harmful effects of acid rain and ozone depletion are also discussed in the lesson. Students define the nutrient that is often limiting to plant growth through...

Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

Eighth graders identify the types of bonds elements form. In this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.
