Gelling and spherification are good hands-on activities when you're studying proteins, as it's the unfolding of proteins that allows the hydrophobic amino acids to cross-link and form a gel.
You can even look up the exact amino acids that make up the gelatin (probably glycine), and you can model those amino acids. You can also chemically test foods for proteins, if you want to make your study as hands-on and context-building as possible.
Syd and I have been working through this Harvard EdX class, Science and Cooking: From Haute Cuisine to Soft Matter Science, and that's where we learned how spherification works. When cooking, you gotta love your polymers!
Although the process that Syd and I used does result in spherified liquids, this isn't exactly the type of spherification that occurs in fancy molecular gastronomy restaurants. There, they use alginate and calcium to build that gel layer only around the outside of what they want spherified, leaving the inside as liquid.
These gel spheres are a solution of liquid and gelatin, and we used physical processes to shape them.
We thought we were probably lost. There were lots of little roads between Traverse City and Sleeping Bear Dunes. Lots of turns onto unlabeled streets, lots of winding country roads, lots of farms and vineyards and orchards full of cherry trees. And when you type a national park into your GPS, you're never quite sure what part of the park it's actually going to take you to. Will you arrive safely at the visitor center, or at a fire tower fifty miles away? The main entrance gate, or the post office where the park gets its mail?
Since we didn't know what to expect, and weren't quite sure where we were going, then, it was even more magical to be driving down yet another little road and suddenly see, to our left, the largest wall of sand I've ever imagined.
It was huge. Incongruously huge. Game of Thrones The Wall huge. Absolutely impossible, except that there it was.
Obviously, we had to climb it!
Okay, climbing a giant sand dune was a little bit like slogging through hell below our feet. But above us?
Only sky.
And look at that view from the top of the climb!
We lounged in place for a while, me recovering my resting heart rate, and the kids playing in the biggest and best sandbox in the Midwest:
Can you imagine living around here and having small children? I'd have taken my two here every single day!
Notice in these photos the concession to Mom's fragility embodied in Will having taken over the Mom Day Pack. Now, Will was the Keeper of Water and Snacks and First Aid Kit and Sunscreen and Bug Spray, and Mom just had to get her own butt up that last dune, the distant figures of her children literally running up that mountain of sand egging her on:
But what did I see when I finally reached the top?
Omg. Another, higher dune.
Must. Climb. It.
And from the top of THAT dune?
Nope. I give up.
Later, when we finally found the visitor center and picked up park maps, I'd learn that the trail we were on was something like three miles round-trip, a distance that we were not prepared to hike with zero prep. If I had this trip to do again I'd have us pack lunches and make a day of just this Dunes Trail, but for three people with just a water bottle each, not even all of us wearing shoes, this was our turn-around point.
Now, to enjoy the lovely walk back!
Although most of us ran most of the way:
After that, my Junior Rangers and I took the Pierce Stocking Scenic Drive. The kids weren't super impressed with most of the stops--I mean, not after a whole morning playing on the marvelous and mind-bending Dune Climb!--but this stop was worth it all:
Despite the dire warnings--

Is that exhausted climber... vomiting?!? |
--and then crawling back up. The kids and I hiked to an overlook where we joined a vocal community of observers of these intrepid adventurers, rooting for our favorites, discussing what we'd do differently were we in their places (god forbid!), offering advice and criticisms, and cheering every time someone finally finished their long crawl back to the top:
Oh, and we also admired the view, of course:
And Syd had a worms and dirt sundae:
