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 />
