Today is Day 73 of our stay-at-home time.
Keep reading to learn more about the live caterpillars at my home AND how to make a jumping frog from a piece of cardboard.
CATERPILLAR UPDATE
The caterpillars are growing! I have had them now for 5 days. Last Wednesday, the caterpillars were 1 cm long. Now, the caterpillars are 3 and 1/2 cm long!
The caterpillars are now making sticky webs and hiding under the web. Do you know why? They do it to protect themselves because the animals that like to eat them, do not like to eat the sticky web.
The patterns of dots and stripes on the skin or exoskeleton change every time the caterpillars molts or wiggles out of its skin. (Insects have their skeletons on the outside of their bodies called exoskeletons. Humans have their skeletons on the inside of their bodies, called endoskeletons.)
These caterpillars have 5 pairs of prolegs (10 prolegs) and 3 pairs of true legs (6 legs).
The old skin or exoskeleton has spikes on it. The caterpillars leaves it behind like an old sock and has new skin and new spikes. The spikes are another way to stop animals from eating them.
The holes on the sides of the caterpillar are called "spiracles" and the caterpillar uses these holes to breathe air.
At this point in the life cycle, some of the caterpillars spikes are white and some are black.
The caterpillar frass (or poop) is in the shape of a cylinder because that is the shape of the inside of the caterpillar.
HOW TO MAKE A JUMPING FROG
Your assignment on Google Classroom today is about the life cycle of the frog. Here is a video that shows you how to make a jumping frog out of a piece of cardboard. It really works!
