Writing Chemical Formulas
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...
Curated OER
Tie Dye
Students 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...
Curated OER
Chemical Reactions
Students work in groups to define chemistry vocabulary including the terms reactants, products, exothermic and endothermic. They then combine the group definitions to arrive at a consensus definition for the class. Students also listen...

Chemistry: The Case of the Sunken Ice Cube
Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...

Understanding of the Structure of an Amino Group
Students review the characteristics of acids and bases. They examine the structure of an amino group and compare amines to ammonia. They work together to develop the concent of polymerization.
Curated OER
Solutions and Suspensions
Students explore matter by conducting an in class demonstration. For this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't...
Curated OER
Intrinsic Viscosity
Students treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.
Curated OER
What is pH?
Pupils describe pH and the importance of it in the natural world. In this Biology activity students compare the pH of different mixtures.
Curated OER
Electron Sqare Dance
Students participate in an Electron Square Dance in which they act the part of atoms. They follow the structure of different atoms suggested by the teacher.

The Synthesis of Some Organic Compounds And Their Representative Structures
Students examine how to represent organic compounds three-dimensionally. They write a synthesis reaction for three demonstrations, and construct a three-dimensional structure using a molecular modeling set.
