Vaccinating kids against sugary drink addiction

It’s sometimes hard to notice against the backdrop of large and extra-large adults, but 1 out of 3 kids these days is overweight or obese, too. Consuming drinks that have sugar, which kids really, really love, is a big part of why, especially because some parents think such drinks are healthy. So I got to wondering what public schools are actually doing to educate kids about the calorie content of beverages. Or, for kids too young to really grasp the calorie concept, how do schools inform kids that drinking too many sugary drinks can make them fat (if, indeed, teachers are allowed to suggest that being fat might be unhealthy)? Given that obesity is the most pressing medical issue facing kids, I would think that public schools would be totally focused on these topics, and would acknowledge that early intervention is better.

Below is the class activity I think all kindergartners should be doing: making a poster showing how much sugar is in common beverages. It’s a common science fair project, but if done in early elementary school the experience might vaccinate them against over-consumption of sugary drinks.

Sugar in drinksThere are lots of ways to do it, but what I like about the one above is that water and plain milk are included. There should also be some common juices (apple, orange, e.g.), of course, because they are loaded with sugar. And just for scale, it might be good to show how many teaspoons of sugar are in a typical bag of candy (e.g., Skittles).

I would further suggest that the poster include a bag of sugar to represent the total number of calories needed for a typical kindergartner (maybe 1 1/2 cups; 1200 calories?). Teachers should clarify, of course, that eating 1 1/2 cups of sugar is not the way kids should meet their daily energy needs. When done, the poster can go out in the hallway to horrify the rest of the school.

Finally, don’t give your poster a weak title like, “Rethink your drink.” Although we know what that means (and it rhymes), try instead to craft something with a more direct message, like, “Don’t drink dessert all day”, “Don’t drink your dessert”, “Sugary drinks are candy drinks”, “Liquid candy can make you fat.” The idea is to be direct, memorable. And to not shy away from the point: sugary drinks can (do!) make kids fat.

I’m making a Pinterest board to collect some good examples, so if you are a public school teacher, please have a look:

DIY olla planter for swamp milkweed

In my futile quest to attract monarch butterflies to my yard, I recently planted swamp milkweed (Asclepias incarnata).  There are other kinds of milkweed (e.g., the orange-flowered A. tuberosa, butterfly weed) that you can plant here (Zone 7A), but adult monarchs really like the flowers of A. incarnata and the larvae really, really like its leaves.  The problem is the plant likes to be consistently watered, which is hard if you leave the house for a few days in the summer.  So I decided to plant a few plugs into a large pot equipped with a makeshift olla.  Ollas are those beautiful, unglazed terracotta containers used around the world to irrigate crops without much water waste: you bury them next to your plant, fill them with water, and then they slowly release moisture into the surrounding soil.

Anyway, photographs of what’s in my garden are probably TMI, but I wanted to share so that others might be guilted into planting some swamp milkweed, too.  If more people maintained host plants, more monarchs will come … and who wouldn’t want that??

If you’re on board, make yourself an olla with a terracotta pot glued to a saucer.  Or use two pots together — just ensure that you’ve got something watertight. I’m fond of Loctite Premium and Gorilla Glue for getting the components sealed together.  Note that you must use unglazed pots. To facilitate filling of the olla, attach something funnel-like.  For this olla I used a lamp reflector bowl that I found on sale at a hardware store; because I needed a little more height, I attached the funnel on top of a little bit of PVC tubing.

Colin Purrington Photography: gardening &emdash; planter-with-plastic-liningHere’s a photograph showing the olla inside the planter.

Colin Purrington Photography: gardening &emdash; olla-with-glass-funnelHere’s a really boring video of water being added to the olla.  But I sped it up so you don’t suffer too long.  But you can skip this and I won’t be offended … I’ve just found that when explaining the olla concept to the uninitiated, they don’t get it unless showed.

Once filled, you can see the porous nature of terracotta almost immediately.  I think this pot is particularly porous (perhaps firing temperature was too low).

Colin Purrington Photography: gardening &emdash; water-seepage-ollaAdd some sort of floating ball to your funnel so that when the water level goes down, the ball acts as a stopper for the olla, preventing evaporation. Other people have caps for their ollas — that works, too.  I’ve never seen balls used before, and they amuse me.  Yes, I’m easily amused.  Also gives me a quick visual for when the funnel level has dropped.

Colin Purrington Photography: gardening &emdash; ping-pong-ball-olla-capAfter you’ve confirmed that olla doesn’t leak from the glued seams, add soil and plants. Of course, if your olla leaks, dry it out and add glue or caulk (the white stuff you see at the bottom).

Colin Purrington Photography: gardening &emdash; swamp-milkweed-in-olla-planterThis shows how the ball (ping pong ball) seals the neck.  Works like a charm.

Colin Purrington Photography: gardening &emdash; ping-pong-ball-olla-cap-sealedNow I’m waiting for the darn monarchs.  I hate this part.

By the way, ollas work well for any plant.  I have about 10 in my garden, all homemade (you can buy fancy ones, but shipping terracotta is expensive).  Really great if you find yourself traveling during the summer, or have plants that don’t tolerate even a single day of neglect.  If you hook them up to rain barrels via a siphon (future post), you can have pots that water themselves entirely.

Mantoloking before Hurricane Sandy

The house is gone.  All we have now are photographs.  Sadness.
