This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry...

A fuel cell is where the jailer keeps gas guzzlers. Scholars review chemical reactions, chemical bonds, and chemical structure in order to apply these concepts. Participants construct fuel cell kits, using electrolysis to run the car and...

Students 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 construct...

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...

Students explore ionic bonding. They draw examples of ionic bonding and explain the activities of the electrons of the elements. Students use paper plates and candy to draw electron configurations of given atoms.

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

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

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

In this kinetics worksheet, students review activation energy, rate of reaction, and reaction mechanisms. This worksheet has 13 multiple choice questions.

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...

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

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.

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 these creative hands-on activities, students construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

Students demonstrate a working knowledge of cell interactions such as DNA replication, protein synthesis (transcription and translation), through active participation in a cooperative group.

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.

A fascinating and engaging lesson on the properties of water awaits you. In it, learners engage in four activities that are designed to teach about the properties of water. This exciting plan has worksheets embedded in it which make the...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

Learners 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. 

The radical reactions of polymers seems abstract to many pupils, but this instructional activity turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and...

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...

Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class...
