Silkworm life cycle

A friend of ours from the 4H Club gave us some silkworms to raise. I had never seen a silkworm before and the only information our friend gave us was that they eat mulberry leaves. I didn’t even know there was such a thing as a mulberry tree, and I doubted I would find any in our neighborhood. But, I couldn’t let go of the opportunity to learn more about silkworms and have the kids experience their life cycle and watch it as it unfolds, day by day, right in front of their eyes. Well, I’m glad we took the silkworms home. We found the mulberry trees at a local park and brought several bags full of leaves home for them to eat. We wrapped the leaves in newspaper and kept them inside large ziplock bags in room temperature. That kept the leaves kind of fresh for a couple of weeks. We also left some of the leaves in plastic bags inside the fridge, and that preserved them even better.

We placed the silkworms in a plastic shoe box and we poked holes in the lid for ventilation. In fact, most of the time, we left the lid slightly open in order to prevent molding and humidity. I guess, as long as they have enough leaves to eat, they don’t try to escape.

The shoe box made it easy for the kids to inspect the silkworms whenever they wanted.

In the beginning, when the silkworms were still small, they didn’t eat that much. But, as they grew, their appetite grew with them. And the more we fed them, the more they ate, and the more they grew… By the time they were two inches long, we had to feed them at least 3 times a day. Basically, they ate nonstop. Perhaps I should mention that silkworms are not very messy, and they don’t smell, but they do poop a lot! We had to clean the box everyday.

Once the silkworms grew larger, I allowed the kids to hold them. I kept a watchful eye on them to make sure they were handling the silkworms gently. I read their skin can be easily damaged. They got quite comfortable with the silkworms as you can see in the pictures below.

In fact, they got way too comfortable… (Dani decided to play with more than one silkworm at a time, and she lost track of one of them. Later I found it walking on her shorts, right at her bottom, and she almost set on it! Ugh… So, a word of advice, only allow playing with one silkworm at a time!).

The silkworm’s skin is very soft, and their pro-legs allow them to attach themselves to almost anything, specially clothing. Also, I might add, they are very ticklish…That make holding them even more fun!

We learned more and more about silkworms as we did our research online and at the library. Here are two very nice books with lots of pictures and information:

We also read the book The Empress and the Silkworm. It  tells the Chinese legend of how silk was discovered about 3.000 years ago.

In addition to the reading, Nico and Dani wrote on their journal and worked on the silkworm life cycle.

Nico also worked on the lapbook below.

The learning experience went beyond science, as we began reading about the historic and economic significance of the silkworm and the silk they make. For that, I highly recommend the book Stories from the Silk Road. It has lots of information about the silk road as well as many interesting stories related to it.

We watched the silkworms make their cocoons and we are now waiting for the moths to emerge. It will take them about three weeks. We can’t wait to see their transformation. They’ll certainly be the subject of another post…

Greetings from California!

The cultural exchange sponsored by the Little Red Farm is still going on and we are still waiting for two more packages to come. Nevertheless, I decided to post some more details about the packages we’ve sent. Rachael, from the Little Red Farm, asked people from the US to focus on the state we are from rather than the country.  In our package, I tried to create a balance of  both, sending information from the US as well as California.

Below, pictures of things related to California:

Reproduction of an orange crate label from our county, Orange County;

A Hollywood key chain;

A couple of little handmade booklets about California;

Seed package of California Poppy, California’s state flower;

Some delicious California raisins;

and a Minnie and Mickey Mouse ears craft.

In addition, we sent some postcards and brochures from Southern California and coloring pages with facts about our state. To the US family, we also sent a California quarter , a California flag, a map and brochures from Yosemite National Park.

The US puzzle (above) , the American flag, and the US currency (below) were sent only to the families overseas.

I hope this post is useful to those just starting the exchange. Start gathering all the stuff and have fun!


An update on our cultural exchange

There were four families in our group: ourselves, one family from Australia, one from South Africa, and another family from the United States. Unfortunately, we only received one package back, and that was from Australia. We never heard back from the family from South Africa, and the US family emailed me back saying they were sending the package within the next few days, but they never did. So, even though we really enjoyed preparing our packages, the whole experience ended up been very disappointing (specially for my older son who would ask me almost everyday where were the packages.) Anyways, keep that in mind. Not everyone will really honor their word. So, if you decide to participate, that’s a risk you’ll have to take. Good luck!



Cultural Exchange

We are participating in a cultural exchange sponsored by Little Red Farm. The exchange is a great way to introduce the kids to other cultures and also learn a little bit of Geography. We sent packages to Australia, South Africa, and to Iowa, USA. Below is a picture of things we included in the package. I might post a detailed description of it later, once the exchange is over.

My kids got really excited when we received our first package from Australia!

They opened the package and here is what they saw:

A boomerang magnet,

Australian chocolate and, below, a small Australian rodent (I’m still trying to figure out what animal this is);

We also got a book, coloring pages, a pencil, some brochures, flag stickers, an animal mask, and a letter with more information about Australia.

What a nice way to get in touch with people from all over the world! It was a really worthy experience for all of us. We are still waiting to receive the other packages, and I’ll certainly post about them also. If you would like to join the cultural exchange, I believe you can still sign up. Just click on the Little Red Farm link above for more information.
