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.

Students create models of ionic and covalent electronic bonds to demonstrate their understanding of these chemistry concepts. They explain how both ionic bonds and covalent bonds work so that younger students can understand.

In this molecules worksheet, students answer post lab questions about types of bonds, factors that determine polarity and molecular geometry. They calculate electronegativity differences in atoms and determine the types of bonds between...

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...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

High schoolers will draw Lewis structures of common covalent compounds using a Chem 3D computer program. They will predict the shapes of the molecules, complete a data table, and formulate rules for predicting shapes of molecules. In the...

Glucose is a simple sugar and a molecule that can be illustrated through modeling. Scientific investigators with visual impairments use hands-on models to reconstruct the process of bonding molecules. The tools used in this activity are...

High schoolers work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

Young scholars demonstrate their understanding of a chemical process.  In this exploratory lesson students create a clay animation that shows how a specific type of chemical bond. 

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Students record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

Primo Levi wrote a collection of short stories comparing his life from Italy to Auschwitz to elements in the periodic table. Pupils read an excerpt from his book and research the characteristics of various elements. Then, they make a...

Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...

Students study acids and how they can be measured.  In this acid lesson students distinguish the properties that create strong and weak electrolytes. 

The purpose of this lesson involves reviewing nomenclature and molecular formulas as well as introducing naming molecular compounds and identifying acids. The students investigate and understand how conservation of energy and matter is...

Junior chemists manufacture biodiesel in the lab. For this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

In this matter worksheet, students calculate volume and partial pressure for gases, compare liquid and vapor phases, and review the characteristics properties of gases. This worksheet has 12 multiple choice and 3 problems to solve.

Pupils practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All proposals...

Students assess how to go from writing ionic chemical formulas to nomenclature and naming chemical compounds. They brainstorm former studies and share their thoughts in small groups. A list of everyday products (shampoos, toothpaste,...

Learners experiment with water as a component of suspensions, solutions, and heat conduction contributing to the use of food and the health and wellness of human beings.

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