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 lesson 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...

Explore endo and exothermic reactions with a laboratory investigation. A simple experiment monitors the temperatures of several chemical reactions. The reactions include both exothermic and endothermic reactions, helping young scientists...

What is the difference between heat and temperature? Learners conduct an experiment and collect data to determine the connection between heat and temperature. The investigation helps them realize that heat may be absorbed or released...

Which has more calories, a cupcake or a rat? The odd question grabs pupils' attention as they learn about food as fuel in an intriguing installment of the PBS food science playlist. The video explains how scientists use a bomb...

How does what you eat compare to an NFL football player? The final video in a 10-part series explains the nutrition requirements at the extreme level of an NFL player. The instructor explains the key nutrients and their nutritional...

There is much more to calories than what you see on a nutrition label. The 34th lesson in a 35-part video series explains calories on a scientific level. The comprehensive video gives examples and shows how to measure calories of a given...

Why do athletes load up on carbohydrates the evening before a competition? The lesson helps answer this question as it relates the type of food to the amount of energy it contains. After a discussion, scholars perform an experiment to...

How do humans get energy since they aren't mechanical and can't photosynthesize? Learners explore this question by relating potential energy in food to human energy levels. Scholars measure the change in mass and a change in temperature...

Increased oxytocin helps people read facial expressions with greater accuracy. Video explores the way this hormone impacts social interactions and highlights the way scientists perform research to confirm the findings. Then the video...

As we get older, we age, our bodies and minds deteriorate, but this isn't true of all species. The video begins with why we age and what biological processes cause aging. Then it covers research on worms, mice, and other animals that...

What is thermal energy? What is the difference between thermal energy and temperature? Answers to these questions are provided by a presentation that also covers conduction, convection, and radiation.

Heat is more than just temperature, as viewers discover throughout a presentation about thermochemistry that emphasizes vocabulary. Definitions include joule, calorie, energy, enthalpy, calorimetry, exothermic and endothermic process,...

Work, energy, and their relationship to power: what is the common thread? Explore this with your class as they learn the concepts of work and energy, both kinetic and potential, before completing multiple practice problems to demonstrate...

Whether you need a new textbook for your health class, or a few exercises and passages for your lesson on nutrition, you'll find what you need with a thorough nutritional science resource. With 15 chapters that cover elements of...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists conduct...

Learners discover how we measure a healthy energy budget for our bodies with this educational video from TED-Ed. It reviews not only the definition of a calorie, but also such concepts as basal metabolic rate and how to properly perceive...

Trying to raise awareness about nutrition and making healthy choices, but can't find a resource that engages students? Then you've come to the right place. In this short video, Jennifer and Rich demonstrate an app called the Eat &...

What is a calorie and how does it work? How many calories do we consume in a typical day, and how many do our cells need to function well? Your learners will answer these questions and more using a worksheet, which includes informational...

What are calories, and how do calorie needs differ from person to person? Here is a worksheet that briefly explains how calories measure the energy supplied by food, as well as suggests the amount of food an individual should eat per day.

Nutritional labels are everywhere, yet so few of us take the time to use them! Here is a instructional activity that learners can use to practice calculating such features as calories, carbohydrates, and serving size based on real...
