Answer:

Take a moment to make some observations about the color, shape, weight, size, and texture of the outside of the cocoon. Gently shake the cocoon and listen for anything inside. If you have a scale, measure the mass of the cocoon. Record your observations in a notebook or on the silk cocoon dissection sheet.

Use your fingers to gently tug at the loose silk around the outside of the cocoon. You may find you are able to remove the exterior silk in one single sheet. Rub this silk between your fingers, describing the texture in your notes, then pin it to your pinboard and label it so that you can compare it to silk collected in later steps.

Now, use a pin to snag some of the second layer of silk from the outside of the cocoon. Pull enough that you can feel it between your fingers and observe its texture, and record your observations. Pin this silk next to the silk you pulled off in the previous step, and label it.

A silkworm constructs its cocoon from the outside in, starting with a quick scaffold that it can easily rest upon while weaving and that will ultimately secure the cocoon to surrounding plants. The silk used to make the cocoon starts out thick but gets thinner and thinner as the silkworm works its way into the center of the cocoon.

Cocoon Interior – What’s inside of a cocoon?

Using sharp scissors, nick the center of the cocoon, creating a hole just big enough to get the tip of your scissors into.

Carefully, cut around the outside of the cocoon along the long axis. Stop periodically to peek into the cocoon and make sure that you are not cutting into anything that might be hidden inside. Cut until you have two halves.

Once you’ve opened your cocoon, take a moment to sketch what you’ve discovered inside. If you have a scale, measure the mass of the empty cocoon and compare it to its original mass.

Using pins, carefully pin the objects that you’ve found to your pin board, and try to identify them based on the information below. Pin one half of the cocoon to your pin board.

After constructing its cocoon, the silkworm caterpillar is fully encased inside. There, it will gradually stop moving and shed its skin-like caterpillar exoskeleton to emerge as a pupa, the intermediate phase between the caterpillar and the adult moth. The exoskeleton, called exuvia, is left in the bottom of the cocoon. A silkworm pupa already looks more like an adult than a caterpillar, with a shortened, segmented body, a clearly defined head, and the beginnings of what will be the adult legs. It takes the pupa approximately two weeks to develop into an adult moth.
