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

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

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

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 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.

Viewers watch an introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis.

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

In this animated object, learners read an introduction to protein structure and function.

In this animated and interactive object, learners identify the valves and chambers of the heart.

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.
