Our first experiment, popping a Peep into the microwave, also doubled as a fun snack, thanks to instructions from About.com. Start with a half a graham cracker, on a microwave safe plate.
Top with a quarter of a Hershey bar (three squares - which also makes it easy to see 3/12 = 1/4).
Add a Peep.
Then, pop the whole plate into the microwave for 20 seconds, and watch the Peep expand to gargantuan proportions (and probably fall off of the cracker), as the microwave causes the water molecules in the marshmallow (do Peeps qualify as marshmallows?), start to move, and heat up, which heats up, and softens the sugar, and gelatin, and heats up the air bubbles, making them expand, and push against the softened sugar walls, until they finally burst through, letting the air escape, deflating the entire thing.
At which point, the science experiment is over, and the snack begins. Remove the melty mess from the microwave. Scoop the marshmallow back onto the chocolate, top with the other half of the graham cracker, and enjoy!

It's great to be a homeschooler.
