Go! Slow! Whoa! As part of a study of the nutritional value of foods available on the school campus, groups label those that are fine anytime as "Go" foods. Those that are okay a few times a week get the "Slow" label while those...

Snacks—even the word can conger up a hunger. Rapidly growing teens, especially, rely on snacks to get them from one meal to the next. After reading a series of articles about nutrition and healthy snack choices, pupils fill out a report...

High schoolers learn why humans need calories, how they control weight with food choices, and the impact of exercise on energy. Scholars then apply their understanding to a case study of lunch choices and exercise.

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

The fifth instructional activity in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.

People associate calories with food, but what is a calorie? Young scientists measure the number of calories in samples of food to better understand the concept. They test a variety of samples, take measurements, and compare their results...
