How to teach kids to waste less food

WASHINGTON — “Waste not, want not.” “Clean your plate.” “Take What You’ll Eat and Eat What You Take.” Many of us heard those expressions growing up and may even repeat them to our own kids. Yet, those warnings have going unheeded. We waste a lot of food in America. In fact, 40% of all edible food in the United States gets tossed. The impact is staggering—from water and energy loss to rotten food and packaging clogging our landfills leading to increased greenhouse gas emissions.  Lessons learned early in life can prompt a lifetime of smart habits, so let’s help students become food waste aware. This document is a guide to teaching students about food waste, with conversation starters, lessons and activities suitable for grades K-12. Hopefully, it will spark student–and maybe even teacher–interest and insights, because we all have to pitch in to prevent food waste.

“What parts can you eat?”

Lesson: Easy show and tell demonstration with younger students regarding which parts of produce are edible as well as some creative ways to use them.  Items needed: any fruits/vegetables that traditionally have parts that go unused. For example, carrots (peelings/tops), potato (skin), radish/beets (greens) or kale (ribs).

Sample script: We all know that carrots are yummy if you cut off the green top, and peel the outer layer.  But maybe that’s not the best way to eat them. 

What parts of carrots or broccoli do we usually throw away?  Can you suggest some ways we might make use of those parts?  Guidance: Carrot greens can be eaten several ways, whether they are a topping for a salad, sautéed with oil and garlic or made into a pesto.  At the very least, they make a great treat for pet rabbits and guinea pigs.  The peels can be used in soup/stock.  And carrots often only need a good washing before eating, no peeling. The same goes for potatoes and sweet potatoes. (And did you know the most nutritious part of the potato is the skin?)  Broccoli stalks are also good to eat used in stir fries, soups/stock and slaws.  You may or may not like beets or radishes, but their green leaves (the part that grows above the ground) are delicious, either sautéed or raw in a salad.
Activity: Do a taste test comparing peeled and unpeeled carrots.  Let students try some broccoli stalks or beet greens (cooked or uncooked). Encourage students to try some of the techniques at home and report back what they find.

Activity: Show video of someone eating an apple (from the bottom.)  Is there such a thing as an apple core (or is that a social construct?)  Would you try this?  (See if students will try, spitting out the seeds.)

Activity: Try eating the peel of a kiwi fruit.  How does it taste and feel?

“Celebrate Individuality Taste Tests” (Beauty is on the Inside!)

Lesson: We all know it’s not respectful to single out people for being different.  We should celebrate our individuality.  Well, it’s no different with fruits and veggies!  Just because a piece of produce looks different, doesn’t mean it tastes worse.  It may actually taste better.  (Especially those tomatoes!  And older fruits are often sweeter as they have high sugar content.)  
Sample script: Did you know that most baby carrots come from odd-shaped carrots that have been whittled down by a machine?  The baby carrot is the core of the carrot.  This method both avoids and causes waste.  Can you think of how that happens? Guidance: Utilizing misshapen carrots helps prevent throwing them away but much of those misshapen carrots are wasted in the reshaping.

Activity: Find an odd-shaped or even blemished carrot and cut it open to reveal a “normal” looking interior. Have the class to do a taste test of “ugly” produce compared to traditional items.  They can even use blindfolds.  Is there a difference?  Ask the class to vote on which tastes better.  This activity can be repeated using various fruits including bananas, apples, peaches and vegetables such as carrots, potatoes, peppers.  Encourage students to try the taste test at home with their families.

Activity: Show students that one blemish or bruise doesn’t ruin a piece of fruit. Find a blemished fruit or vegetable (pears, apples, bananas all work well). Cut the fruit in half to show that the bruise doesn’t go all the way through. Then pare away the rotten part and ask students if they’d like to taste the
