In this PhET activity, students will be able to visualize chemical reactions by viewing 3D representations of atoms and molecules.
In this PhET Activity, students will explore the relationships between the pressure, volume, temperature, and density of ideal gases.
In this PhET Activity, students will model molecular shapes by creating 3D ball-and-stick images. Students will explore the effects of adding and removing bonds and/or lone pairs of electrons.
In this PhET Activity, students will generate data from a population of rabbits in different environments. Students will introduce mutations and/or environmental factors that affect rabbits’ traits and adaptations.
