In this investigation, learners gather information on various food items during a field trip to a local grocery store.

In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.

In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?
