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

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

Students identify the parts of a triple beam balance and practice measuring the mass of objects.

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

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. Check out our video on relative position: https://bit.ly/2kTXujp

In this animated object, learners are introduced to the structure and function of animal cell organelles.

In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.

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

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

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.

Learners view an explanation of how to read a graduated cylinder by measuring the lowest portion of the meniscus. A quiz completes the activity.

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