"Strange Amber" PPT courseware 5

Introduction to Amber

Amber is fossilized pine resin from ancient times and can be used as decoration. Plant debris and various ancient small animals are often wrapped in the plant fat of fossils such as amber. In the honey-like color, you can often find a fly's wing or a small beetle, wisps of which are clearly visible. It can be said to be varied and colorful.

Amber: A very hard, yellowish to slightly brown translucent resin fossil, produced in alluvial soil, lignite seams or some seashores. It is easy to polish. It is mainly used for decorations (such as beads and cigarette holders) and can be used as traditional Chinese medicine. .

What would have happened if it hadn't been such a coincidence?

①. The spider swooped over, swallowed the fly, and swaggered away. Only then did the rosin drip down, and there would be no more strange amber;

② If the spider has just eaten the fly and before it has time to escape, the rosin will drip down. Although there are two small insects wrapped in it, people can only see the spider.

③ If the spider is about to pounce, but the fallen rosin has already wrapped the fly, the spider will never fall into the trap.

Conditions for the formation of rosin balls

In summer, the sun is strong──the rosin oozes out

Old pine trees─can exude large drops of rosin

Flies and spiders encounter rosin──and are wrapped in it at the same time

The rosin continues to drip down──accumulating into rosin balls
