Information on certain man-made boards? Plywood, Block/Chipboard and MDF!?

So yeah, it’s for a piece of homework. I got all the Softwoods and Hardwoods covered, but I need help on Man-Made Boards.

I need info on
• Plywood, Blockboard, Chipboard and MDF → Sources | Used to make | Physical Properties | Working Properties | Costs |
• Costs of → Oak | African mahogany | Teak | Balsa | European redwood | Stika spruce | Parana pine | Red cedar |

The costs bit isn’t necessary, but would help as an extension ;D

Thank-you!

see http://www.diydata.com/materials/manmadeboard/manmadeboard.php you would need to contact for prices I can only get UK£ prices.
hope that helps
