about the life cycle of silk worms

Top Ten Reasons this is THE BEST Pre School in the Bay Area

1. Stephanie, the owner, has a degree in child development, and from the moment I walk in the door it is clear that the learning environment is created based on the developmental readiness of the children.

2. The learning environment is ALWAYS changing, so the kids stay interested and engaged. The students recently had the opportunity to witness the full life cycle of silk worms. It was an amazing science project. Even my 7 and 9 year old children could not wait to visit the silk worms each day.

3. The big beautiful backyard is the perfect place to spend the day playing and learning. I love that when weather permits they spend a majority of the day outside. There is even a outdoor classroom!

4. The staff. While the school is small, about twelve students, there is a staff of four. WOW, what a student/teacher ratio.

5. The food. The vegetarian meals are prepared fresh daily. This is where my son gets his veggies each day. Once he gets home, I can forget about it.

6. The respect and understanding that the staff has for each student. When you speak to the teachers it is clear that they know your child.

7. The attention to details. At Beansprouts parent teacher conferences are held. My husband and I snickered at the idea of a conference for a preschooler, but we walked out amazed. Stephanie had video taped the students in the learning environment, and during the conference she explained the developmental behavior patterns that were displayed or being developed. I saw kids playing...she saw kids learning and growing.

8. The weekly photos! Stephanie post photos of all the fun activities the kids do during the week.

9. The open line of communication between the school and home. They are always willing to listen and to share their observations.

10. The fact that when on vacation in the Bahamas my son asked to go to Beansprouts. Given the choice Bahamas or Beansprouts, he wanted Beansprouts. That is reason enough alone. When he is dropped off each day, he cannot get into the classroom fast enough!

Life Cycle Life cycle of silk worms has four stages: such as egg, Larva, Pupa and moth. Domesticated Mulberry silk worms are univoltine, bivoltine and multivoltine. Univoltine silkworm completes one generation, Bivoltine complete two generation and multivoltine silk worm completes 5-6 generations per year. The univoltines lay diapausing eggs and only hatch once in a year at spring season. Bivoltines lay both type of eggsdiapausing eggs and non diapausing eggs which hatch in spring season and autumn season. Multivoltine don’t lay diapausing eggs. Eggs: The size, weight, shapes and color of the eggs varies with the silkworm races, season and nutrition of mother moths at larval stages. Generally the eggs are ovoid, spherical or ellipsoid in shape and flat on one side. The female moth lays Figure 3: Life cycle of Bombyx mori 400-500 eggs on mulberry leaves or artificially prepared butter cups. 100 eggs weigh about 60 mg. the silkworm eggs hibernated during winter will hatch in spring when the mulberry sprouts. Generally the eggs hatch in 9-11 days at proper temperature and humidity condition. Larvae: The larvae are polypodous or eruciform type. The head is hypognathous, heavily chitinized and bright brown in color. There is spinneret, as the median process, at the distal portion of the labial prementum through which silk glands open and silk exudes. It has three pairs of ocelli or simple eyes. The thorax bears 3 pairs of cornical short, jointed true kegs and the prothorax has a pair of spiracles laterally. Abdomen has nine visible segments as the 9th, 10th and 11th segments are fused to form the apparent ninth segment that bears the paired prolegs one in each. The 3rd, 4th, 5th and 6th abdominal segment bears paired prolegs one in each. The dorsum of the 8th segment has a projection called caudal horn. The first eight abdominal segments have a pair of spiracles laterally. The larvae go through four moults and have five instars. The newly hatched worms are black in color and covered with bristles and thus resemble tiny black ants at a glance so called ant worms. The worms are about 3mm long, have 13 segments.
