Curated OER
Technology of the Deep: Experiments with Buoyant Forces
Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.
Curated OER
What Is Chemistry, Anyway?
Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.
Curated OER
Periodic Trends
Students identify the different periodic trends. In this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.
Curated OER
Paper Structures
Students demonstrate that material strength varies with shape and arrangement.
Curated OER
SLIME!
Students learn the effects of friction and examine how certain lubricants can only be used with certain materials.
Curated OER
Making Paper
Students explore how natural earth materials are processed into a human-made product. They simulate a manufacturing process by making paper. Students review the importance of recycling in preserving our natural earth resources.
Curated OER
Oxidation And Corrosion
Students sort tarnished metals by type and experiment with different cleaning solutions and techniques to restore them to their natural color and shine.
Curated OER
Chemistry - Atoms and Elements
Learners perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.
Curated OER
Ideal Gas Law
Pupils explain and use ideal gas law and use the law to solve problems. They use conversion factors to convert mass to mol. Also students use stoichiometry skills previously learned.

Und: Properties of a Pure Substance [Pdf]
Often we find that different phases of pure substances can exist in equilibrium with one another. Let us consider an important gedankenexperiment (Latin-German for "thought experiment") in which we boil water. Ordinary water boiling is...
