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

Using the periodic table of elements, young chemists fill in a chart of isotopes to show the atomic number, mass, charge, number of protons, number of neutrons, and number of electrons. The chart is followed by 11 questions that...

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

Perfect for reviewing atomic components, this activity simply consists of a large, easy-to-read chart of 11 elements. Chemistry learners fill in the missing element symbol, number of protons, neutrons, and electrons, the atomic mass and...

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...

This science presentation focuses on the elements in the periodic table. It begins with the parts of an atom, explaining atomic mass and atomic number, valence electrons, and isotopes. Then it moves on to discuss various ways of...

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.

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...

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...

The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...

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...

Familiarize your new chemists with the periodic table of elements by contemplating this collection of slides. Element groups are identified, atoms are defined, and nuclide notation is explained. Isotopes are also mentioned. The topics...

Young scholars explore scientific theories and the works of scientists.  In this chemistry lesson students develop a timeline  that shows how scientists work was built on the ones before them. 

In this models of atoms and isotopes worksheet, students use marshmallow of different colors to represent the protons, neutrons and electrons in an atom. Students make models of the 3 isotopes of hydrogen. They draw a diagram of each and...

Atomic structure is reviewed with connection to the gain or loss of electrons. The movement of electrons and the resulting behavior is summarized. Practical uses of static electricity is explained, with diagrams of the most common...

In this chemistry worksheet, students identify and name the number of neutrons, electrons, and protons for each. Then they illustrate how the electrons are arranged in a cloud. Students also find the relative number of atoms in the two...

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...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

Get a charge out of a great resource! Scholars use an interactive to explore addition and subtraction of integers. They add or remove electrons in an atom model to consider its charge.

Did you know many insects use cohesion or surface tension to walk on water? Using a presentation, scholars learn the more important properties of water. It extends into the concepts of solutions, suspensions, pH, and more.

Here is an engaging and hands-on lesson plan that allows high school chemists to demonstrate the effects of a catalyst on various chemicals. They garner knowledge of how reactants and products differ from one another, while...

Elementary schoolers discover how electricity travels and create an electron flow through a closed circuit. They work together to make a closed circuit and observe the electricity being made. This outstanding lesson plan is well worth...
