# Display of the Month: Sugar Math

It’s time for a brand-new Display of the Month!

This month, I want to feature Sugar Math: an engaging and memorable way to teach valuable lessons about added sugars and good health.

Let’s dive right in!

The Materials:

The Activities:

The Details:

Set up your space as pictured above, adjusting your arrangements to fit the activities you’ve chosen and the space provided.

For the Sugar Quiz, pose the following questions to your group. You can divide them into teams and track points to declare a winner at the end or simply address volunteers individually. Don’t forget to offer Water WristbandsStickers, and Bookmarks as prizes for correct answers or for the winning team.

1. True or false: A healthy diet should include no more than 10% of its calories from added sugars. (true)
2. How many calories per day is the upper limit for added sugars for the average person? (200)
3. And what is that in grams of sugar? (50)
4. Where can you find added sugars? (on the new nutrition facts label, or point to the general list of sugars in a food and explore how to intuit how much of those sugars is added)
5. Roughly how many teaspoons of sugar make up the average upper limit for daily added sugar intake? (12)

Now let’s talk about the Yogurt and Added Sugar Measurements Activity. You may need to rearrange your table for this one.

Gather your group around the table and hold up a clean, empty container that was once used to hold yogurt. Ask everyone how much sugar they think was in that container. Take guesses (if people are shy at first, use prizes like the Water WristbandsStickers, and Bookmarks as motivation for contributing), then show them where to find the answer on the label. Hold up a few more containers and repeat the process.

Pick a container of yogurt and have people use a teaspoon to measure out how much sugar is in that container (provide a dish of refined sugar and a few spoons for this purpose) assembling it all in a clear zip-top baggie. You can also use these amazing Sugar Test Tubes.

Do the same thing with the other containers of yogurt, discussing their findings as they go. How much sugar is in that yogurt? How much of it appears to be added sugar? Why?

If you have the resources, a Sugar Presentation is also a fun way to make lessons about added sugars more memorable. Cue up a projector (or your laptop) to show either the Added Sugars DVD or Sugar Scoop PowerPoint, or both! The PowerPoint comes with additional handouts, which you can distribute after the presentation.

Other Display Ideas:

Here is a collection of the past displays of the month. Which will make an appearance at your next health or wellness fair?

And here are some fantastic sugar resources, fresh from the Nutrition Education Store!

# To Thump or Not to Thump: A Watermelon Quiz

Try this fun quiz from Cheryle Jones Syracuse to celebrate watermelons while promoting good health…

I often wonder when I see people at the grocery store thumping on watermelons. Do they really know what they are listening for?

There’s an old saying about thumping a watermelon:

A good watermelon should sound hollow… like if you thumped your chest.
If it sounds like thumping on your stomach… it’s definitely too ripe.

Now I’ve given this saying some thought, and I’m not sure that I could judge any of those sounds. There has to be a better way to evaluate these fruits. I did some research, consulted with some colleagues, and have returned with a fun quiz that offers insight into how to select, store, and prepare watermelon. Of course, I’ve also included information about a watermelon’s nutrient content and health benefits. What better way to celebrate National Watermelon Day?

The quiz is available in the text of this blog, and an abridged version is also available as a downloadable handout! So check out the options below and, if you like what you see, get the handout for free!

See the yellow “belly” on that watermelon?

Watermelon Quiz:

How much do you know about watermelon? Take this quiz and find out!

1. True or False? Uncut whole watermelon should be refrigerated.
2. True or False? Since you’re not eating the rind, you don’t need to wash the outside of a watermelon before cutting into it.
3. True or False? The red pigment in watermelon is a good source of the phytochemical lycopene.
4. True or False? The “belly” of a ripe watermelon should be yellow.
5. True or False? Like the name implies, watermelon is made of mostly water.
6. True or False? Watermelon does not really have any nutritional value.
7. True or False? Watermelon is a good source of potassium and sodium.
8. True or False? The rind of a watermelon should not be eaten.
9. True or False? It’s okay to swallow watermelon seeds.
10. True or False? The “hollow” heart sometimes found inside a watermelon is caused by someone dropping the melon.
11. True or False? Watermelon is a cousin to cucumbers and squash.
12. True or False? A good way to tell if a watermelon is ripe is by giving it a good thump.

1. FALSE: Uncut whole watermelon can be kept in a cool, dry place and does not need to be refrigerated. Stored this way, a watermelon will keep for 7-10 days at room temperature. Once cut, leftover watermelon should be covered and refrigerated. Be cautious of purchasing cut melons at farmer’s markets if they have not been kept cool after cutting. Use cut watermelon within 5 days.
2. FALSE: The outside rind of the watermelon should be washed before you cut into it. Bacteria found on the outside may easily be transferred to the interior during cutting. Before slicing up your watermelon, be sure to wash your hands and wash the melon under cold running water. You may need to use a clean brush to help scrub off excess dirt.
3. TRUE: There may be up to 20 mg of lycopene in a two-cup serving of watermelon. Studies have shown that people with diets high in lycopene have a reduced risk of prostate, breast, and oral cancer. The redder the melon is, the more lycopene it contains.
4. TRUE: A yellowish spot on the underside or “belly” of a watermelon indicates that it is ripe. This spot should not be white or green — if it is, then it means that the watermelon is underripe.
5. TRUE: A watermelon is 92% water, which makes it light in calories and a good tool for proper hydration. A two-cup serving of watermelon contains only 80 calories and counts for two servings of fruit.
6. FALSE: Watermelon is an excellent source of vitamins A and C. A 2-cup serving provides 25% of your needed daily Vitamin C and 30% of the needed Vitamin A. It’s also a good source of vitamin B6 and contains 1 gram of fiber and 20 grams of natural sugar.
7. FALSE: Although watermelon is a good source of potassium, it is low in sodium, with zero fat and zero cholesterol.
8. FALSE: Watermelon rind is edible and can even be delicious. There are a variety of recipes available for items made with watermelon rind. Try using it in everything from slaw to chutney to pickles.
9. TRUE: Despite what you may have heard when you were growing up, watermelon seeds will not grow in your stomach. It will not harm you to swallow watermelon seeds. Some people even save them, dry them, and eat them as a snack. The small white seed coats that are often found in “seedless” watermelons are seeds that have not matured. These “seeds” are sterile and, if planted, will not produce a watermelon.
10. FALSE: The “broken heart,” “hollow heart,” or cracked center that is sometimes found inside a watermelon is caused by weather conditions during the growing season. This flesh is still good and safe to eat. Some folks say watermelon with a these internal cracks are sweeter due to concentration of the sugars.
11. TRUE: Watermelon are a vine crop and must have honeybees pollinate the blossoms. Watermelon is in the same botanical family as cucumber, pumpkins, and squash. Seedless watermelons are created by crossing different kinds of melons and are not genetically modified. There are many varieties of watermelons available and options include: seeded, seedless, mini, yellow, and orange.
12. FALSE: Unless you are a very experienced watermelon picker, it is difficult to tell if a watermelon is ripe solely by evaluating the sound you make when thumping on it. A good watermelon should be symmetrical, heavy for its size, and firm. It should have no cuts, dents, or bruises. Also, look for a pale or buttery yellow “belly” and a dry stem end near the base of the fruit.
