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 learning activity you'll review the safety equipment used to protect a worker's face and ears.

Learners assess the periodontal status and the health risk factors of a fictitious patient. They also make treatment recommendations in this interactive lesson.

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.

In this learning activity you'll practice reading and interpreting a paychecks and paycheck stub.

In this screencast, learners examine hearing and balance. Detailed drawings of the outer, middle, and inner ear structures are included.

Learners listen to a lecture given during the early days of nanotechnology titled, “There’s Plenty of Room at the Bottom.” Dr. Richard Feynman made the presentation to the American Physical Society on December 29, 1959. Animation makes this lecture fun to absorb.

In this learning activity you'll establish your budget by determining your earnings, expenses, and goals.

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.

Learners examine the components of the x-ray tubehead, a sealed, heavy metal housing that contains the x-ray tube that produces dental x-rays. This object is designed to help students understand the functions and safety features of the tubehead.

Students identify the enamel, cementum, cementoenamel junction, clinical crown, clinical root, and epithelial attachment of a tooth.

Dental x-rays are generated in the dental x-ray tube. Through this animated learning object, students will learn the steps in x-ray generation from turning on the x-ray unit to exposing the dental x-ray film.

Play this game to challenge your friends on their knowledge of developmentally appropriate and inappropriate practices in early childhood education.

The tubehead is a sealed, heavy metal housing that contains the x-ray tube that produces dental x-rays. This learning object will provide students with practice identifying and labeling the dental x-ray tubehead.

In this interactive game, learners review emergency medications. For every right answer, the learner earns a square on the tic-tac-toe board while playing against the computer or another contestant.

Users of this learning object evaluate the early online experiences of four hypothetical students and record the lessons that can be learned about what to do and what not to do to create effective online learning environments.

In this animated activity, learners examine the components of the dental x-ray tube and how dental x-rays are generated.

Students locate the enamel, cementum, cementoenamel junction, the anatomic crown, and the root of a tooth in this interactive lesson.
