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.

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

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.

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 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.

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.

In this animated object, learners examine water molecules moving through a semipermeable membrane.

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