Curated OER
Pauli's Magical Water
Learners predict the shape of molecules using VSEPR theory. For this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Developing a Theory About the Nature of the Contents of a Sealed Box
Students observe the changes of a closed chemical system. They record and analyze the data as they manipulate the system. They answer questions to end the instructional activity.
Curated OER
Wolf Pack in a Bottle
Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
Human Evolution
Students make and use observations of Laetoli footprints to provide clues to life in the past. They collect and analyze data to study the relationship between foot length and body height.
Curated OER
From Genomes of Species
Students investigate genomic research being done and its potential for understanding, treating, and possibly curing human genetic conditions. The potential of proteomic research as a companion to the work being done with genomics is...

How to Design an Experiment
Students work together to develop and implement an experiment. They investigate the properties of nylon and construct a mobile of organic materials. They share their experiments with the class.
Curated OER
Forces on the Human Molecule
Learners conduct several simple lab activities to explore the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In this activity, students play the role of molecules in a beam...

Heat Transfer and Pollution
Students perform computer simulations on air dispersion. In this chemistry lesson, students calculate energy transfer based on specific heat and temperature change. They explain the causes of smog.
