Reading a Triple Beam Balance
By Jill Crowder
Students identify the parts of a triple beam balance and practice measuring the mass of objects.
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.
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.
Identifying Eukaryotic Animal Cell Organelles
By Barbara Liang
In this animated object, learners are introduced to the structure and function of animal cell organelles.
Measuring Volume Using a Graduated Cylinder
Learners view an explanation of how to read a graduated cylinder by measuring the lowest portion of the meniscus. A quiz completes the activity.
Biomolecules - The Lipids
In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
Biomolecules: The Carbohydrates (Video)
By Becky Polk-Pohlman
Viewers watch an introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis.
The Cell: Passive Transport Diffusion
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.
Biomolecules - The Proteins
In this animated object, learners read an introduction to protein structure and function.
Eukaryotic Cells: Assembling the Cell
By Kristine Snow
In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.
Anatomical Terminology: Body Regions
Students identify the various regions of the human body through drag-and-drop exercises.
In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.
