10 Healthy eating activities to try with your students

Teaching students about healthy eating goes well beyond a poster of the food groups on the classroom wall. In a country where childhood obesity affects nearly one in five children and adolescents (CDC, 2024), helping students understand the impact of what they eat is one of the most practical things educators can do.

The challenge, of course, is making nutrition education stick. A lecture about vitamins and minerals rarely holds a room of 7th graders. But a hands-on label-reading activity, a short video that breaks down ultra-processed foods, or a taste-test experiment? That’s a different story. When students connect nutrition concepts to their own plates and daily choices, the learning becomes personal and lasting.

The good news is you don’t need a full health curriculum to get started. With video resources, discussion prompts, and a few well-placed activities, healthy eating fits naturally into science, math, health, and even social studies. Below, you’ll find 10 classroom-ready activities organized by grade level, each paired with ClickView videos to bring the learning to life.

Why healthy eating belongs in your classroom

Nutrition isn’t just a health class topic. It connects to science (how nutrients fuel the body), math (reading labels, calculating percentages), social studies (food access and food deserts), and even media literacy (analyzing food advertising). That cross-curricular reach makes healthy eating a natural fit for standalone lessons, interdisciplinary projects, and quick discussion starters alike.

It’s also deeply relevant to students’ everyday lives. How many of your students grab a bag of chips from the vending machine after school, skip breakfast before first period, or choose an energy drink over water? These are real decisions students make every day, and giving them the knowledge to make informed choices is one of the most transferable skills you can teach.

Elementary activities (grades K-5)

1) Explore the food groups with a sorting challenge

Understanding the five food groups is a foundational nutrition concept, and younger students learn it best when they get physically involved. This activity pairs direct instruction with a tactile sorting challenge that reinforces what students learn from video.

Start by watching Food Groups and Nutrition as a class. This short video introduces the main nutrients we take from food and explains why each one matters for a healthy body. Then try this:

• Collect images of different foods (cut from magazines, printed from the internet, or drawn by students)
• Label five stations around the room with the food group names: grains, protein, dairy, fruits, and vegetables
• Give each student or pair a handful of food images and ask them to sort the foods into the correct group
• Wrap up with a quick discussion: which food groups did you eat from today? Which ones are missing?

For a deeper look at why balanced eating matters, follow up with The Importance of a Balanced Diet and Nutrition and Health. For your youngest learners (grades K-2), Learn about Eating Healthy Foods with Ant Active presents these concepts in a fun, animated format.

2) Spot the tricks in food advertising

This is one of those activities where students can get genuinely fired up. Food marketing aimed at children is everywhere, and once students learn to recognize the techniques, they start seeing them in every commercial break and grocery store aisle.

Watch Food Advertising to Kids: The Tricks to Watch Out For as a class. This 18-minute video explores how advertisers target young people and the questions students should ask when they see a food ad. After viewing:

• Bring in (or have students bring in) examples of food packaging and print ads
• In pairs, students identify at least one persuasive technique the packaging uses (bright colors, cartoon characters, health claims, fun shapes)
• Each pair presents their finding(s) to the class: what trick(s) did the advertiser use, and why does it work?
• As a class, create a “smart shopper” checklist of questions to ask before believing a food ad

This activity builds critical thinking and media literacy alongside nutrition knowledge. It works especially well for grades 4-5 and ties naturally into any unit on persuasion or advertising.

3) Sing, move, and learn about fruits and vegetables

For younger elementary students, music and movement are powerful learning tools. This activity turns nutrition vocabulary into something students remember long after the lesson ends.

Play the Fruits and Veggies Nutrition Song and have students follow along. Then try these extensions:

• Fruit and vegetable show-and-tell: Each student brings in (or draws) their favorite fruit or vegetable and shares one fact about why it’s good for you
• Taste test challenge: Set up a tasting station with a few unfamiliar fruits or vegetables. Students try each one and rate it on a simple scale
• Create a class cookbook page: Each student contributes a drawing and a sentence about a healthy snack they enjoy at home

For additional video support, the Fruit Song and Fruit Names videos work well as warm-ups for grades K-2. You can also explore the broader Healthy Lifestyle topic on ClickView for more resources on diet, exercise, and wellbeing.

Middle school activities (grades 6-8)

4) Investigate ultra-processed foods

What’s actually in the food your students eat every day? This question tends to get a strong reaction from middle schoolers, and it’s a powerful entry point into conversations about food quality, labeling, and health.

Start with the ClickView video Ultra-Processed Foods from the Spotlight On series. This six-minute video explains what ultra-processed foods (UPFs) are, how common they’ve become in the American diet, and why health experts are concerned. After watching, guide students through a label-reading exercise:

• Bring in (or have students bring in) packaging from common snack foods and drinks
• In pairs, students list the ingredients they recognize versus the ones they don’t
• Discuss as a class: what makes a food “ultra-processed”? Why do manufacturers add these ingredients?
• Have each pair write a short recommendation: should this product be eaten regularly, occasionally, or rarely? Why?

This activity develops critical thinking about food choices while reinforcing the idea that healthy eating isn’t just about avoiding “junk food.” It’s about understanding what’s in the food we eat. Pair it with You Are What You Eat, which walks through the MyPlate guidelines and explains how to make smart food choices.

5) Connect diet to mental health

Here’s a conversation many students haven’t had before: what you eat affects how you feel, not just physically, but mentally.

Watch Why Diet Might Be a Big Deal for Mental Health as a class. This SciShow Psych video explores the emerging research on the gut-brain connection and how nutrition influences mood, focus, and mental wellbeing. After viewing:

• Lead a class discussion: have you ever noticed feeling different after eating certain foods? What about when you skip a meal?
• In small groups, students create a two-column chart: “foods that support brain health” versus “foods that may hurt focus and mood”
• Each group shares their findings and the class builds a combined list
• Challenge students to track what they eat and how they feel over three days, then reflect on any patterns

This pairs well with the broader Healthy Lifestyle topic on ClickView, and you can extend the conversation using Don’t Put Too Much Pressure on Yourself to connect diet to stress management.

6) Study the world’s longest living people

What do the longest living people in the world have in common? This inquiry-based activity taps into middle schoolers’ natural curiosity and turns a broad health topic into a research project.

Use the ClickView video Extremes: Episode 2, which investigates the habits and behaviors of the world’s longest living people. After watching the relevant segment:

• Introduce the concept of “Blue Zones,” the regions where people consistently live past 100
• In small groups, students research one Blue Zone and identify the dietary habits common to its residents
• Each group presents their findings, focusing on: what do these diets have in common? How do they differ from a typical American diet?
• As a class, create a Venn diagram comparing Blue Zone eating habits with the average U.S. diet

This activity combines nutrition education with geography and research skills. It also gives students a real-world, evidence-based reason to think about what they eat. For a broader look at healthy lifestyle choices, follow up with Be the Change You Want to See and People Stay Healthy.

7) Design a balanced meal plan

This activity puts students in the role of nutritionist and asks them to apply everything they’ve learned. It works well as a culminating project for a nutrition unit or as a standalone lesson.

Begin with The Importance of a Balanced Diet and Healthy Habits to review key principles. Then:

• Give each student (or pair) a specific budget and a list of grocery prices for common foods
• Students design a one-day meal plan (breakfast, lunch, dinner, and one snack) that stays within budget and includes all five food groups
• They calculate the approximate cost and identify which food groups each meal covers
• Groups present their meal plans to the class, explaining their choices and any trade-offs they made

Why does a bag of chips cost less than a bag of apples? That question alone opens the door to conversations about food access, economics, and health equity. For a math connection, have students calculate percentages of daily nutrient intake or compare the cost per serving of different foods. Explore the full Healthy Lifestyle topic on ClickView for further video support.

High school activities (grades 9-12)

8) Decode how vitamins and carbohydrates work

High school students are ready for the science behind nutrition. This activity moves beyond “eat your vegetables” and into the biochemistry that explains why certain nutrients matter.

Use two TED-Ed videos from ClickView: How Do Vitamins Work? and How Do Carbohydrates Impact Your Health?. After watching both:

• Divide the class into “vitamin experts” and “carbohydrate experts”
• Each group creates a visual explainer (poster, infographic, or digital slides) that answers: what does this nutrient do in the body? What happens if you get too little, or too much?
• Groups teach each other using their visual aids
• Wrap up with a discussion: how do popular diets (low-carb, keto, plant-based) align with what we’ve learned about how these nutrients actually work?

For students interested in a deeper dive into food science, pair this with Ultra-Processed Foods from the Spotlight On series, which examines how food processing strips away nutritional value. You can also explore the Nutrition and Physical Activity topic on ClickView for related resources.

9) Analyze the link between nutrition and wellbeing

This activity asks students to think holistically about how diet connects to physical health, mental health, and daily performance. It’s ideal for health, psychology, or biology classes.

Start with You Are What You Eat, then layer in Why Diet Might Be a Big Deal for Mental Health. After viewing both:

• Present students with three case studies: a student-athlete training for a competition, a student struggling with focus during exams, and a student dealing with low energy and poor sleep
• For each case study, small groups recommend dietary changes that could help, citing evidence from the videos and their own research
• Groups present their recommendations and the class debates: which changes would have the biggest impact? Are any of the recommendations unrealistic?
• Individually, students write a reflection: what’s one change you could make to your own eating habits based on what you’ve learned?

This ties in well with the broader Healthy Lifestyle topic on ClickView, which also covers sleep, exercise, and mental health. For a connection to physical activity, add Physically Active You to show how diet and exercise work together.

10) Launch a “be the change” healthy eating campaign

This project-based activity puts students in the driver’s seat and challenges them to apply their nutrition knowledge to create real change in their school community.

Watch Be the Change You Want to See as a class to set the tone. Then:

• In small groups, students identify one healthy eating challenge in their school (limited healthy options in the cafeteria, vending machine choices, lack of nutrition information, and so on)
• Each group designs a campaign to address their chosen issue: a poster series, a social media plan, a proposal to school administration, or a short video
• Groups present their campaigns to the class (or to school staff, if possible)
• Debrief as a class: what makes a health campaign persuasive? What would actually change student behavior?

This activity combines nutrition education with persuasive communication, design thinking, and civic engagement. It also gives students agency over their own learning environment. For inspiration on building healthy habits beyond diet, explore the full Healthy Lifestyle topic on ClickView, which covers sleep, exercise, mental health, and technology use.

Tips for ongoing healthy eating integration

Teaching healthy eating doesn’t need to be a one-off lesson. Here are a few ways to weave it into your classroom routine throughout the year:

• Use video as a bell ringer. Short clips like Why Is a Healthy Lifestyle Important? or Moderation work well as quick warm-up activities that spark discussion
• Connect it to current events. New dietary guidelines, food recalls, or nutrition research in the news all make great five-minute discussion starters
• Make it cross-curricular. Healthy eating connects to math (label reading, budgeting), science (nutrients, digestion), social studies (food systems, food access), and media literacy (food advertising). Look for natural entry points in your existing units
• Involve students in real decisions. If your school has a wellness committee or a say in cafeteria options, encourage students to participate. Giving them a voice in food-related decisions reinforces everything they’ve learned

Healthy eating is one of those topics that touches every student’s life, every single day. Whether you’re working with kindergartners sorting pictures of fruits and vegetables or high schoolers designing a school-wide nutrition campaign, you’re helping students build knowledge and habits they’ll carry with them long after they leave your classroom.
