In this activity (on pages 10-15), learners investigate starch in human diets and how plants make starch (carbohydrates) to use as their food source.

In this food science activity, learners observe different plant-originated foods.

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

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

Although we may not admit it, all humans fart or pass some gas. In this activity, learners make their own model to mimic food passing through intestines and discover what releases gas.

In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

In this biology activity, learners recreate the process of digestion in a zip lock bag. A bit of soda pop added to some crumbled crackers approximates how acids in the stomach dissolve food.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

This simulation helps learners understand what happens to food as it passes through the digestive system.

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

In this biology activity (page 8 of the PDF), learners will explore how saliva assists in the beginning of the digestive process.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

Your tongue can sense about 6 different flavors (salty, sweet, bitter, sour, umami/savory, and fat), but your nose provides a lot more "taste" information than you realize when you eat.

Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!

In this simulation activity, learners act as parts of the circulatory system and discover how it serves as a transport system for food/nutrients, oxygen, carbon dioxide and waste.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
