...A solid piece of hickory the exact size of a piece of balsa wood will displace the same volume...

Wrong. If the object in question has a density less than that of water, it will float. Then the weight of the water displaced will exactly equal the weight of the floating object. As Hickory is a higher density wood than Balsa, then if they are exactly the same size, the (heavier) Hickory will sink farther into the water before it begins to float, thus displacing more water as compared with the less dense (lighter) Balsa. If we were talking about solid materials whose density was greater than that of water, so that when immersed they would completely sink rather than float, and we wanted to measure their volume, then yes, the amount of water displaced by two different samples of equal dimensions would displace exactly the same amopunt of liquid when immersed, but it wouldn't tell us anything about the weights of the samples, only their volumes.

Aaaaahhh, there ya go, jumpin' to confusions, Mart the Fart did not specify that they would displace the same volume of water, simply that it would displace the same volume. It will, indeed displace the same volume of air.

BUT, back to the original post; I think she oughtta just pile up a bunch of all four kinds they got, set 'em on fire, and cook up a mess of hot dogs, burgers, and marshmallows

Eight years old Marty. Eight.

1.) Take a big pine split , burn it, and then record the max temp and how long it burns.
2.) Take a big oak split, burn it, record mas temp, and how long it burns.
