In this screencast, explore the legislative, executive, and judiciary branches of the U.S. government. External resource: www.usconstitution.com

In this animated activity, learners view the various hand, arm, and shoulder muscles in action. The students test their knowledge of the location of the muscles in a drag-and-drop exercise.

Students view an enlarged, colorful depiction of the contents of an average square inch of skin.

Learners complete a matching exercise as a quiz or as a review of state laws and rules pertaining to barbers and cosmetologists.

Learners read about the types of clothing considered appropriate for a childcare setting. This activity is designed for students enrolled in an early childhood education program.

The learner constructs a nail and identifies the terms relating to the structures of the nail in a matching exercise.

In this screencast, we'll view the 10 major bones of the skull and read a description of each bone.

The purpose of this learning object is to introduce the learner to the different processes of science.

Students read about the process of hair growth beginning with the joining together of amino acids.

In this animated lesson, learners read about the disulfide bond, the second strongest chemical bond in the hair. This bond can only be altered by chemicals.

In this screencast, students identify various muscles of the face and scalp and see them in action.

In this animated object, learners examine how changes in pH affect the salt bonds in strands of hair.

In this interactive object, learners examine the characteristics of effective visual displays. This activity is designed primarily for instructional assistants.

In this interactive object, learners identify the different roles generally assumed by teachers and instructional assistants as they form a partnership in the classroom.

Learners consider the steps and supplies to use when diapering infants and toddlers. The proper diapering procedure not only meets basic care and sanitation needs but builds relationships and promotes the child’s learning. Brief quizzes complete the learning object.

Learners play a game to review concepts connected with student assessment. The categories on the game board are "General Assessment," "Science Assessment," "Math Assessment," and "Famous Scientists."

Learners read about the types of clothing considered appropriate for a school setting. This activity is designed for students enrolled in an instructional assistant program.

In this animated object, students examine the shades that result from mixing primary and secondary colors. Color tone and level are also defined.

In this interactive game, learners answer 30 questions about early childhood education activities and skills. Up to three people can play on the game board at one time.

in this screencast, learners examine the formation of radial and concentric fractures as an object breaks a pane of glass.

In this animated object, learners examine how the sensory, motor, mixed, and reflex nerves work in the human body.

Discover how to select the correct fingerprint powder, the proper dusting and collecting techniques, and how to fill out an evidence card.

In this interactive object, learners identify the elements of the Windows platform in a drag-and-drop exercise.

Learners watch video clips demonstrating the correct procedures for police officers to follow when entering and clearing a room.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.
