As long as the online class teaches the rules of your state, then an online class would be helpful. If it's just basic information, it could be a waste of time. Be sure you practice driving with your child.

fossils as imprints of a plant or animal in a rock
imprint cast and mold are both creating a clone or another item from one item into another exact alike item .
One form of fossil forms when an organism dies and its body is covered by layers of sediment. As time passes, the organism itself, particularly when composed primarily of softer materials, is eroded and carried away, leaving a negative imprint of its body. This type of fossil is called a mold. A cast fossil forms when a mold fossil is filled with some form of mineral, usually through the seepage of water depositing the minerals within the mold. In time, the mold is filled and the materials deposited harden, creating a replica of the original fossil. This is called a cast fossil.
A mold is a fossil created by the encasement of an organism in rock, where the organism decays away after solidification of the encasing structure, leaving behind an impression of the original organism. An additional stage is a cast, where the mold is back filled by sedements to create a solid model of the original organism.

Mold filled with minerals
📷 Organisms buried in sediment slowly decompose, leaving a cavity that contains an exact imprint of the organisms' shape and size. When this hollow space fills with material, this material takes the shape of the mold, forming a cast.

The Cast is the fossil of the shell etc itself. The Mould is the hollow left in the surrounding rock if the fossil is removed artificially or by some natural event such as differential dissolution or mass-movement.
A mold is a form into which molten metal is poured. When the metal hardens, it takes the shape of the mold. This process is called casting.

mold
A fossil mold is formed by the impression left in rock by the remains of an organism. A cast fossil occurs when the mold is filled in by precipitating minerals.
A MOLD is used to make a cast.
