In this learning activity you'll study the structure of the cell membrane and construct it using the correct molecules.
Learners read a brief introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis are shown.
In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.
In this interactive learning activity, learners review the terms used to describe relative position of body parts in order to have a common set of words to describe their position.
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.
In this animated object, learners read an introduction to protein structure and function.
Students identify the various regions of the human body through drag-and-drop exercises.
In this interactive object, learners identify 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 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 examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.
The student identifies the anatomical parts of the ear and learns the purpose and function of these parts. A review follows the lesson.
In this animated object, learners examine water molecules moving through a semipermeable membrane.
In this interactive object, learners identify a person's regional body parts.
In this animated and interactive object, learners identify the valves and chambers of the heart.
In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.
Learners examine the structure and function of skin including the production of melanin.
In this animated and interactive object, learners examine ABO blood antigens and Rh antigens and their compatibility.
In this interactive and animated object, learners read a description of the number, name, and function of the cranial nerves. A matching quiz completes the activity.
In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.
In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.
Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.
In this interactive object, learners examine the locations of major body cavities and their protective membranes. A drag-and-drop exercise completes the activity.
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
The learner listens to the pronunciation of medical terms using a "jukebox" to select the terms.
