Essential Nutrient Worksheet

9th - 12th

In this nutrients worksheet, students identify the functions and sources of 7 essential nutrients and answer 17 questions about the digestive system, a balanced diet, proteins, organic molecules and vitamins.

Resource Details


Protein Puzzles

Students examine the concept of protein structure. They read an article, construct a three-dimensional model of an insulin protein, take a quiz, conduct Internet research, and answer discussion questions.

Digestive and Excretory System

Students investigate the digestive system and the excretory system. In this biology lesson, students discuss healthy eating habits, diet and weight. They differentiate between an eating disorder and good eating habits.

Nutrients in Lake Water: Too Much of a Good Thing?!

Learners investigate nutrient concentrations in lake water. In this biological communities lesson, students experiment with nitrogen and phosphorus cycles using real life situations.  Learners discuss watersheds, runoff, and both natural and non-natural sources. 

Excretory System

Students investigate the structure and function of the excretory system of the human body. Breathing, sweating, and urinating are explored as important components of the system.

Nutrient Cycling

AP environmental science or college-level ecology classes will glean a tremendous amount of information on nutrient cycles from this detailed PowerPoint. It covers nutrient requirements, biogeochemcial cycles, decomposition rates, and plant adaptations when nutrient conditions are low. There are diagrams and flow charts to help explain the concepts. The 53 slides of information will require a few class sessions to dispatch.

Nucleic Acids

A lively presentation presents general facts and history of nucleic acids in a note-taking format. Every slide contains colorful photos or graphics to illuminate and engage. Biology aces learn about the function and structure of these essential molecules. After showing this presentation, have them create models of the double helix out of various craft materials.


Learners study carbohydrates and what they do for your body.  In this health lesson students examine the different types of fiber, sugar substitutes and popular diets. 


Students examine protein, what it is and how it functions in the body.  In this protein lesson students study the food pyramid, what a protein is and what it does. 

Ruminating on the Digestive System

Students compare the digestive systems of the buffalo and of the zebra, diagram their systems, and compare their lengths. In this digestive system lesson plan, students learn about their diets as well.

Testing for Lipids, Proteins and Carbohydrates

Students perform tests for the presence of certain macromolecules.  In this health and biology lesson, students rotate in groups to three lab stations and perform tests for proteins, lipids, and carbohydrates found in familiar foods.

I've been playing around in the account all morning and I have to say I'm very impressed! The site is amazing! I'm also a Title I tutor (and a summer tutor) so this will help me out a TON when coming up with materials for my students both during Title I tutoring and summer tutoring! The amount of time Lesson Planet will save me is going to be mind blowing!
