Heat Transfer: Conduction, Convection, Radiation
By Laurie Jarvis, Deb Simonson
In this animated activity, learners explore three major methods of heat transfer and practice identifying each.
The Anatomy of the Heart
By Wendy Dusek
In this animated and interactive object, learners identify the valves and chambers of the heart.
By Barbara Liang
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.
Construction of the Cell Membrane
By Becky Polk-Pohlman, Barbara Liang
In this learning activity you'll study the structure of the cell membrane and construct it using the correct molecules.
Biomolecules - The Lipids
In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
The Fungi Kingdom: Common Characteristics of Fungi
Learners examine what defines a fungus and read how fungi differ from animals and plants.
White Blood Cells
