Learning Plan

The current earth is our home for human survival, but have you ever thought about who lived on this land before us, and who was the earliest owner? Yes, it’s a dinosaur!

How did the dinosaurs become extinct? The children all said it vividly: dinosaurs were frozen to death, starved to death, dinosaur eggs were eaten by other animals, some said they were not adapted to the weather, and some said they hit planets. They are all right.

Fossils are the relics of ancient creatures buried in the ground. The most common fossils are formed by teeth and bones.  After the death of ancient animals, the internal organs, muscles and other soft tissues of the corpse quickly decayed.

The teeth and bones have less organic matter and more inorganic matter, but they can be preserved for a longer time.
If the body happens to be buried in the sand and cut off from the air, the decay process will slow down. There is slow-moving groundwater in the silt gap.
On the one hand, the water flow dissolves the minerals in the rocks and sand, on the other hand, it precipitates the excess minerals in the water or becomes crystals.
With the water flow, it will gradually infiltrate the bones buried in the sand, filling the teeth and bones with decayed organic matter. Then how will it become the fossil?

It’s the important content of this lesson。
