where the OPPOsaurus children shall crush the competition.... My daughter’s are having a science fair. The first thing I thought was a volcano with real fire but thats kinda lame. Whats a good 2nd grader science project. But wait, there is more..... I need two cuz I have twins. OR possibly one that they could each have a part.
THE RULES
Nothing that causes harm or stress to humans or animals
No live vertebrate animals may be brought to the fair
No bacterial cultures
No controlled substances
No dangerous or combustible chemicals
No open flames
No food or snacks allowed due to allergy concerns
At least one adult must accompany the student during the fair

I did a few battery operated circuits to power lites and a fan when I was in second grade. My mom is super handy and I loved going to radio shack, haha.
I honestly don’t think you can go wrong with a volcano, bigger is better!
Another cool one is a mini diorama of waves that shows how tides move and shape the sand.

as awesome as I could see that going, you are somewhat restricted in what you can do. I updated with the rules in the post.

o...and to answer your question, the fair runs for an hour, they have to set up a little booth, limited to 3'x4'

Pffft, you act like I can’t do something mind blowing with those restrictions!
....Granted, most are beyond 2nd grade material.
Honestly your best bet would be something like lemon batteries and show the difference between series and parallel wiring with a race between two electric slot cars or something.

Automated p otato cannon home defense turret grid controlled via Alexa, with Google glass HUD integration for when manual control becomes necessary.
... I’ll admit I skipped your rules.

How about what fruits and vegetables can produce enough power to light a lightbulb (CFL/LED)? One could use fruits and the other veggies. Or how solar power works? You should be able to go to a Harbor Freight and pick up a cheap solar panel.

Electroplating coins could be a good one.
Growing crystals is also always good.
If you want a good one that leaves behind keepsakes, the Tollen s’ Silver Mirror reaction is always a crowd pleaser

that sand thing would be kinda cool, they had touched on erosion in class a while back.

I don’t know if it would win anything but the coolest science fair project I ever saw in school was someone who made a mountain diorama to hold a model pneumatic railway made from clear tubing. Seriously cool looking. Is that science? I don’t know, but... Hyperloop!
In any event:

they could make a little house (of course cuz i’m an architect) with a light, light switch, powered by a lemon.

You just described designing a slot car race powered by fruit, w/ comparing parallel vs series....dude, there’s no way a 2nd grader is putting that together ad explaining it effecti vely but I love your ambition!

A fusion reactor? Or is that more of a 3rd grade project.

Seeding supersaturated solutions is also cool and impressive.
Density gradients are also neat when you layer different colors, though not dynamic.

Counterpoint, if you ever get annoyed at the teachers, faculty, etc.... Made a project that involves spring-loaded glitter.

Lots of cool stuff you can do with water.
A little submersible fishtank pump, some silicon tube, some dirt and some water lets you create a river and demonstrate ero sion
A squeeze bottle of water hooked to a sausage balloon, with the balloon submerged at one end of a tank of water, makes a wave generator, which you can then use to also demonstrate erosion, or toy boat stability, or to create artificial reefs using other balloons full of sand (get this just right and you can demon strate left and right hand surf breaks)

Benham’s Disk for one of them:
You can mount it to a battery powered drill if you don’t have little electric motors laying around. The effect is an artifact of how the human eye works and how different color receptors persist differently. It also demonstrates that white is prismatic and contains all the colors.
For the other kid, demonstrate RGB colors by making a Maxwell Color Wheel
That’s the original, if you have red, green, and blue segments you can spin them to make colors. Red+green=yellow, red+blue=magenta, and blue+green=cyan all three together give you white and if you mix them in different ratios you can make other colors.

Eh, I did solar cell powered boats in third grade. Got to use a soldering iron for that one!

Grow gourmet mushrooms on different substrates. Blue oysters would be the easiest. You can grow them on, practically any grain. Hardwood sawdust.
