Visualizes direction and quantity of glass particles as the glass is impacted by a force.

Visualizes direction and amount of glass particles travel when impacted by a force.

in this screencast, learners examine the formation of radial and concentric fractures as an object breaks a pane of glass.

In this learning activity you'll assembles parts of a virus and match virus terms and descriptions.

In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.

Learners conduct an experiment to illustrate how a greater number of particles in a "vessel" increases osmotic pressure.

Learners examine radial and concentric fractures in glass to determine the sequence of the impacts.

Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.

In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.

Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).

Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object.
