Learners read about the mutations that occurred in plants for the successful transition from an aquatic to a terrestrial existence. The classification of plants is based on these adaptive structures.
Passive Transport: Filtration and Facilitated Diffusion
In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.
In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.
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.
Learners use this Structured Query Language tutorial to gain an understanding of how a SELECT statement is built. This learning object has audio content.
Learners view a mind map of the social-conflict Approaches and answer questions about the inequalities, competition, and power found in social structures.
In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.
Learners read a general description of the function and structure of leaves and examine drawings and microscopic views. A matching exercise completes the learning object.
In this screencast, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.
In this learning activity you'll discover three factors that affect group performance: group cohesiveness, communication structure, and individual roles.
