30 minutes

Approach

Interactive slides, discussions, hands-on activities, and reflection.

Materials

Calories 101, Portion Talk, Portion Plate Challenge, My Plate Reflection, Nutrition Label Printouts, Paper Plates, Markers, and Snack Food Samples

Prep

Prepare Materials

15 minutes

  • Review the Calories 101 slide deck
  • Print enough Nutrition Label Printouts for each student pair

  • Prepare blank journals or reflection sheets for My Plate Reflection

Step 1

Introduction to Calories

5 minutes

  • Have pairs share one surprising fact about their label with the group

Step 3

Portion Talk Discussion

5 minutes

  • Use discussion prompts from Portion Talk
  • Ask: “How does eating more than one serving affect calories?”
  • Guide students to connect portion sizes with calorie intake

Step 4

Portion Plate Challenge

8 minutes

  • Give each group a paper plate, markers, and Snack Food Samples
  • Students design a balanced snack plate and label each portion with estimated calories
  • Groups briefly present their plates and reasoning

Step 5

My Plate Reflection

5 minutes

Slide Deck

Calories 101

Exploring the energy in our food

Welcome, everyone! Today, we’ll explore what calories are and why they matter. Get ready to fuel your curiosity!

What Is a Calorie?

• A calorie is a unit of energy provided by food and drink.
• Think of it like fuel for your body—just like gas for a car.

Define a calorie in simple terms and relate it to everyday energy needs. Emphasize that calories aren’t ‘good’ or ‘bad’ on their own—they’re just fuel.

Why Calories Matter

• Provide energy for daily activities (walking, playing, thinking)
• Support growth and body functions (breathing, heartbeat)
• Excess calories get stored as body fat

Walk through each bullet. Explain that if we eat too few calories, we don’t have enough energy; too many, and our bodies store the excess as fat.

Serving Size & Calories

Nutrition Label Example:
Serving Size: 1 cup (240 mL)
Calories per Serving: 150

Point out how serving size affects calorie count. Explain that labels always list calories per serving, not necessarily the entire package.

Quick Check!

Estimate the calories in:
• 1 medium apple
• 1 slice of cheese pizza

Engage students by having them guess real-life calorie amounts. Encourage discussion about why their estimates might be high or low.

Discussion

Portion Talk Discussion Guidelines

Objective: Explore how portion sizes influence calorie intake and make connections between serving sizes and overall energy consumption.

Discussion Rules:
• Listen respectfully and build on each other’s ideas.
• Speak clearly and support your thoughts with examples from nutrition labels.
• Ask clarifying questions if you’re unsure about someone’s point.


1. What Do Serving Sizes Tell Us?

  • Prompt: “Look at the serving size on your label. What surprised you about the amount listed?”
  • Follow-up:
    • “Why do you think companies choose that serving size?”
    • “How might your perception of ‘one serving’ differ from the label?”



2. Multiple Servings and Calories

  • Prompt: “If you eat two servings instead of one, how many calories do you consume? Explain your calculation.”
  • Follow-up:
    • “How easy or hard is it to stop at one serving?”
    • “What strategies could help you keep track of servings when snacking?”






3. Favorite Snack Analysis

  • Prompt: “Name your favorite snack. Guess the serving size and calories per serving.”
  • Follow-up:
    • “How does your guess compare to the actual label?”
    • “Would you choose a different portion if you knew the calorie count?”











4. Balancing Calories and Satisfaction

  • Prompt: “How could you adjust your snack to lower calories but keep it filling?”
  • Follow-up:
    • “What foods could you add or remove?”
    • “How might portion size and food type impact your energy levels?”



Wrap-Up: Ask volunteers to share one new insight they gained about portions and calories. Encourage them to apply this understanding when choosing snacks later in the day.

Activity

Portion Plate Challenge

Objective:
Students will create a balanced snack plate, measure portions based on serving sizes, estimate total calories, and reflect on their choices.

Materials Needed:
• Paper plates
• Snack Food Samples (fruits, veggies, crackers, cheese, etc.)
• Nutrition Label Printouts
• Markers or colored pencils

Directions:

  1. Plan Your Plate (1 minute)
    • Choose 3–4 different snack items.
    • Discuss with your group why you picked each item (taste, nutrition, fun).
  2. Measure Portions (2 minutes)
    • Look at the nutrition labels and identify the Serving Size and Calories per Serving for each item.
    • Use paper plates to estimate how many servings of each food you’ll include.
  3. Assemble & Label (3 minutes)
    • Draw sections on your plate using markers.
    • Place your snacks in each section.
    • Next to each section, write: food name, servings chosen, calories per serving, and total calories (servings × calories).
  4. Calculate Total Calories (1 minute)
    • Add up all the calories from each section to get your plate’s total.
    • Write the total in the center of your plate.
  5. Group Presentations (1 minute per group)
    • Share your plate with the class.
    • Explain how you balanced taste, nutrition, and calories.
    • Discuss one challenge you faced when choosing portions.

Reflection Questions (in your journals):

  • What surprised you about the total calories on your plate?


  • How balanced (fruits/veggies, protein, grains) was your snack? What would you add or remove next time?


  • What strategies will you use to keep snack portions in check when you’re at home or a friend’s house?





Wrap-Up:
Choose one reflection question to share with the group. Discuss how this activity could help you make healthier snack choices.“}
