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...

Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...

Students construct an origami models of different molecules. In this chemistry lesson, students explain what expansive soils are made up of. They discuss what happens when this expansive soil expands or shrinks.

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

High schoolers explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and...

Students cuminate their study of molecular structure and bonding with this activity.

Students listen to the teacher introduce VSEPR theory and explain molecular geometry. They use balloons to visualize the shape of orbitals. Students create visuals of molecular orbitals with strings and balloons.

Students work together to explain the VSEPR theory and how it relates to molecules. They name electron pairs that can surround the central atom of an organism. They discuss the factors that determine the polarity of a molecule as well.

Students analyze the amount of space required to pack round objects. For this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

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...

After learning that the sum of interior angles for triangles is 108 degrees, take it further to show that the sum of angles in any polygon is the same! Using hexagons, pupils practice finding the measure of the six congruent angles. Make...

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Students 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.
