Ward’s Investigating Digestive<br />

Processes Lab Activity<br />

Discover Where Our Bodies<br />

Break Down Food<br />

Before food can be used as fuel, certain enzymes in various<br />

parts of the body must break it down into a usable form.<br />

Re-create this process and allow your students to observe<br />

the action of different types of enzymes found in the body.<br />

Students alter pH and temperature to see how these factors<br />

affect the enzymes; determine where in the body<br />

starches, proteins, and fats are digested; and test for digestion<br />

byproducts. The kit includes materials for six setups, a<br />

teacher’s guide, and student copymaster.<br />

Ward’s Bomb Calorimetry<br />

Lab Activity<br />

Investigate the Relationship Between<br />

Chemical Structure and Food Calories<br />

Determine the amount of energy (number of calories) contained<br />

in various types of food that you supply by having<br />

your students create a simple bomb calorimeter. Once they<br />

have built their calorimeter, they will apply principles of biochemistry<br />

and molecular structure to predict which foods<br />

contain the most energy and then calculate the number of<br />

calories generated from a food sample. The activity contains<br />

enough materials for four setups, as well as instructor, student,<br />

and assessment manuals. Note: This activity must be<br />

performed underneath a fume hood.<br />

Food Chemistry Module<br />

Lab Activity<br />

Discover What’s Really in Your Food<br />

While most food products we buy have ingredients listed,<br />

how do we know what’s really in them? Students utilize<br />

chemicals and test solutions (included) to define and test<br />

for the presence of additives, preservatives, emulsifiers,<br />

stabilizers, thickeners, and non-calorie sweeteners. They’ll<br />

also learn to identify sugars, lipids, starches, and proteins;<br />

detect iodine in salt; test vitamin C; and more. The kit<br />

includes enough materials for 24 students.<br />

Two-Point Aesthesiometer<br />

Evaluate Cutaneous Sensitivity<br />

and Touch Threshold<br />

The sliding scale measures the ability of a subject to distinguish<br />

between two points of stimuli on the skin, while the<br />

plastic points minimize the influence of temperature. The<br />

scale, printed directly on the device, measures up to 14 cm<br />

in 1 mm increments. Size: 6"L x 3/4"W.<br />
