Chemistry: The Collapsing Can
Students observe methods by which air can crush aluminum cans. As water in the can boils and is sealed, the can collapses as it cools. When the procedure is reversed, the can expands to its original shape. After the alternate experiment,...

Thermochemistry: Heat and Chemical Changes
What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists conduct...
Virginia Department of Education
States of Matter
Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to boil water through...
Curated OER
The Big Balancing Act
Students describe chemical changes occurring in hydrothermal circulation systems. They make inferences about the significance of these systems to ocean chemical balance compared to terrestrial runoff.
Curated OER
Equilibrium
In this equilibrium worksheet, students predict the concentrations of solutions at equilibrium and apply Le Chatelier's principle to systems at equilibrium. This worksheet has 15 multiple choice questions.
Curated OER
Equilibrium Equations
In this chemical reactions activity, students calculate the equilibrium constant for given reactions. Students decide if reactions are homogeneous or heterogeneous and if the equilibrium favors reactants or products. This activity has 4...
