Authoritative PPT Summary
"New Life Hatched from Silkworm Eggs" Animal Life Cycle PPT
Part One: Observing Silkworm Eggs
Let's raise silkworms and observe the growth and changes of silkworms throughout their lives.
The life of a silkworm starts from an egg, and a silkworm egg is a life. Observe the color, size, and shape of silkworm eggs. Observe carefully, what else do you find?
Newly laid silkworm eggs are light yellow. They look flat and nearly round with a magnifying glass. Use a ruler to measure them. They are about 1 mm long and about the size of sesame seeds. If they are kept at room temperature, they will gradually turn purple-black.
New life hatched from silkworm eggs PPT, Part 2: The little life emerging from the egg
The little silkworms are about to hatch from the eggs, and we need to build a comfortable "home" for the little silkworms that are about to hatch.
Silkworm eggs are generally stored in the refrigerator and placed at room temperature after being taken out. The most suitable temperature for incubation of silkworm eggs is about room temperature 25°C. The eggs will gradually turn purple-black and the larvae will hatch in about two weeks. After the larva bites open the egg shell, it first exposes its head and then crawls out of the egg shell.
The body color of the newly hatched silkworms is brown or dark brown. They are very small, about 2-3 mm long, and have many fine hairs. They look a bit like ants, so they are called ant silkworms. Although the ant silkworms are small, they wriggle very quickly, and the fine hairs on their bodies will become less obvious after about two days.
Tips on raising silkworms
Silkworms love to eat mulberry leaves. As soon as the eggs are hatched, use a brush or feather to gently brush them onto the mulberry leaves.
To keep the silkworms well fed, the mulberry leaves should be fresh and kept dry, cut into pieces or strips.
Frequently remove silkworm feces and leftover leaves to keep the silkworm "room" clean.
Place the baby silkworms in a well-ventilated area, and do not spray pesticides in the room where the silkworms are raised.
