One out of three kids these days is overweight or obese, and consumption of drinks that have sugar is likely a big part of why, especially because some parents think such drinks are healthy. Sugar drinks also cause tooth decay (I know, big surprise there), and might even cause little kids to be aggressive. So I got to wondering what public schools are actually doing to educate kids about the sugar content of beverages. The answer: not a whole lot, at least from a cursory search of the internet.
So here’s the class activity I think all kindergarten classes should do: construct a poster for the hallway or classroom wall that visually displays how much sugar is hidden in common beverages. Here’s an example:
This project would fit in perfectly with most state standards (for example, see page 10 in Health Education Content Standards for California Public Schools). And because it includes numbers (of teaspoons), teachers can use the poster content to visually drive discussions about addition and subtraction. If this poster was done in a fun way, the experience might vaccinate kids against over-consumption of sugary drinks for the remainder of their lives. The parallel to brushing teeth might be appropriate: you teach kids how to do it even though the chemistry of decay is beyond their understanding. If you don’t brush and floss, you’ll lose your teeth. That’s a lesson best taught when really young.
There are lots of ways to make the poster, but what I like about the one above is that water (no sugar) and plain milk (contains lactose … which is a sugar) are included. There should also be a sampling of common juices (apple, orange, e.g.) 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).
Poster titles matter here, just like they do at a scientific meeting, in that they can provide a take-home message. “Rethink your drink” is a popular title (it rhymes), but I prefer something that confronts the point more directly. Here are some ideas: “Don’t drink dessert all day”, “Don’t drink your dessert”, or “Sugary drinks are candy drinks”. If snark is allowed in your district, then something like, “Sugar is a sweet way to gain weight!” The idea is to be direct and memorable and to not shy away from the point: sugary drinks can (and do!) make kids fat.
If you want some background information relevant to lesson plans on sugar for K-3 levels, here are some resources from BrainPOP. If you’re looking for more examples of posters, here’s a Pinterest board where I collect them:
