Students solve a molarity problem in a drag and drop exercise.

Learners read the definition of atomic weight and obtain the weights of elements by viewing the Periodic Table and charts that list atomic weights by name or symbol.

In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.

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 learning activity you'll review how every protein molecule of an organism is synthesized by that organism in a prescribed process. This activity helps students understand the fundamental life process of making protein.

The student identifies the anatomical parts of the ear and learns the purpose and function of these parts. A review follows the lesson.

In this animated and interactive object, learners examine ventilation, external and internal respiration, and gas transport.

In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.

In this learning activity you'll examine force, mass, and acceleration to understand this "Law of Acceleration."
