Learners read about the world's largest rain forest. A map is provided.

Students match images of insects and other pests with their descriptions in this lesson on keeping a food service operation free from contamination.

In a drag-and-drop exercise, the learner considers various food items and determines if they improve brain functioning. This learning object is designed for instructional assistants.

Learners follow the path of a protein food from consumption through digestion to absorption into the bloodstream.

Learners follow the path of a carbohydrate food from consumption through digestion to absorption into the bloodstream. In a matching exercise, students identify the main type of carbohydrate found in four different foods.

In this learning activity you'll brainstorm and compose a list of speech topics.

Learners take a close look at the information on product labels concerning fat, fiber, and serving sizes. A quiz follows the lesson.

Learners read about the U.S. Department of Agriculture's guide for daily food choices. They then recreate the Food Guide Pyramid.

Students locate the seven countries in the Sahel region, which is between the Sahara and the coastal rain forests. They identify the famous city of Timbuktu in a map exercise.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

In this animated lesson, students read how reducing the thickness of a food is an important factor in cooling it. They also read FDA guidelines for food temperatures.

Students read how to record relevant information on a test tray evaluation form. They enter their own analysis of the data in a practice exercise.
