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 read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.

This screencast will help the student identify normal blood cells and their functions. This will include the identification of red blood cells, five types of white blood cells, and platelets.

Learners examine the relationship of individual parts in an assembly drawing. Assembly drawing notes, fabricated and purchased parts, and sectional views are explained briefly.

In this interactive object, learners identify the parts of an animal cell and its organelles.

In this animated activity, learners examine nanotechnology applications that are based on cell membrane structure and function.

In this video, learners view the parts of an animal cell and its organelles.

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

In this learning activity you'll discover what the .NET Framework is, what problems it solves, and how it came to be.

At the end of this lesson you will be able to

- Explain what biosecurity means.

- Describe why biosecurity is important.

- Identify what kinds of disease agents we try to prevent or control with biosecurity.

- Demonstrate disease agent-host-environmental interactions that result in disease.

Learn more about debugging including: what it is, why we use it, and what it looks like in action.

Learners examine the different stages of maturation for red blood cells, white blood cells, and platelets. 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.

Learners identify the parts of speech by following a certain order until each word in a sentence is labeled. In a variety of exercises, learners practice finding verbs, prepositional phrases, subjects, nouns, pronouns, adjectives, adverbs, and conjunctions.

In this screencast, students view a basic wheelchair and identify its parts.

In this animated activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.

The learner reads about the kinds of questions that are most effective to use on student questionnaires evaluating instruction. Generic evaluations are less helpful than evaluations focused on the specific types of instruction and learning expected in a content area. Sample questions are provided.

Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.

This learning object demonstrates the process by which antigens are identified, processed, and presented to mediators of the cellular immune system.

In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.
