You can out smart him and give him more than 25.
Check out the link and print the page and take it in.
There is another link on that page at the bottom called Chemical composition of living beings. That will give you even more resources and info.
Have fun getting the upper hand this time, but be nice to your teacher. Please.

A good number of the non-metals outside of the noble gasses can be found in living organisms: C, H, O, N, S, Cl, Br, F, I, Se. You will also find a fair number of metals in various forms, such as Ca, Na, K, Co, Cu, Fe, and Mn.
Not sure if there's a place on the web that would give you a list of all 25

water, earth, fire, wood, ether,
I have no idea - I was taught that over 80 percent of the body is water (in medical school)
But I have no idea what elements you mean. Maybe I know to much about the subject - or maybe too little.
It would be nice if you explained to me what you mean with elements.
Or do you mean it is a chemistry question and you mean the elements of the periodical system.
Then I would have to say I would have to look that up. I never had that in medical school.

I know a few of them, but certainly not all 25.
Let me think for a moment:
1. Carbon
2. Oxygen
3. Hydrogen
4. Silicon
5. Potassium
6. Iron
7. Calcium
8. Nitrogen
9. Sodium
And lots more. : )
