Homework help: Scientific models (6th Grade)

My son has a huge presentation to do on scientific models. The three models they need to represent are:

Mathematical
Physical
Conceptual

He can use illustrations from the web, actual models, or drawings. He has to do 24 different examples. Some of the ones we came up with are:

Photosynthesis
DNA strands
Sound waves in the human ear
Light waves
Solar system
Lunar eclipse
Aerodynamics (for vehicles) using air

If anyone can help out with some suggestions it would be greatly appreciated. He is in 6th grade, so it can't be anything too crazy/advanced that he won't understand at all.

Thanks!!

Freud's levels of consciousness - Conceptual
Parts of an atom - Physical

Basically any high-concept mathematical formula like surface area, Ohm's law, conservation of momentum, derivatives of motion, etc.

Not sure where something like exploded diagrams of items like cars or computers would fit under; if your kid gave a good enough reason, I'm sure it could fit in conceptual.

How about the evolution of models? Atoms used to be stacked up like blocks, they they they were like the raisins in raisin bread, then they were like little solar systems, and then they were probability clouds. The moral is that new models are created to incorporate new data, and that science changes in response to additional facts.

I've always been fascinated by how large the universe is estimated to be.

There's a bunch of videos on youtube. But they are either narrated by little kids, or have rap music in the background. There's also a cool Flash (or whatever) thingy that someone posted on this forum once. It lets you scroll from a quark to as far out as we can guess.

You could do a model of mhg83's sexual exploits.

What about creation science? that's a good scientific model for you.

If you do this, you have to include the pictures of the people he's been with.

And I think that the lunar eclipse one would be easier than the volcano. Just be sure to use a bright LED light as the sun so that the shadow on whatever "Earth" is (maybe a grapefruit?), is a sharp shadow.

You could try electromagnetism, or barring that, magnetism. There's a really cool trick where you pour milk into a bag of cereal and use a magnet to gather up the iron LOL

Thanks guys, some great ideas (...except for mhg83's sexual exploits, he's only in 6th grade)!!!

Combustion cycle of an automobile engine or a jet engine would be good.

Re: Homework help: Scientific models (6th Grade)

I can recommend Web sites with models (mostly simulations), but the instructions for the assignment are perplexing. How does the teacher define mathematical, physical, and conceptual model? Many physical models have a mathematical basis, and they may be designed to teach a concept. Oh well.
