In this animated activity, learners explore three major methods of heat transfer and practice identifying each.

Students identify the various regions of the human body through drag-and-drop exercises.

In this interactive learning activity, learners review the terms used to describe relative position of body parts in order to have a common set of words to describe their position.

In this video you'll study the structure of the cell membrane and construct it using the correct molecules.

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.

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

In this interactive object, learners identify the parts of an animal cell and its organelles.

In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
