- Proteins: Essential for the growth and repair of body tissues. Found in foods such as meat, fish, eggs, and legumes.
- Fats: Provide energy and help in the absorption of fat-soluble vitamins. Found in foods such as butter, oils, and nuts.
- Vitamins: Essential for various bodily functions, including immune system support and cell growth. Found in a variety of fruits, vegetables, and dairy products.
- Minerals: Essential for maintaining proper bodily functions and structures. Found in foods such as leafy greens, dairy products, and whole grains.
- Water: Essential for hydration and various bodily functions. Found in water, fruits, and vegetables.

Energy
Students who demonstrate understanding can:
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.
