Where are the insects you found in summer now?
Let's find where they are! Be careful about this kind of Rove Beetles.
You can find some by looking ground very closely like this.
Like this? Now, let's do some experiments!
Pour hot water into a big bottle and a small bottle. Touch the bottles after a few minutes.
You see insects like this small bottle can easily loose their heat.
Then, let's do another experiment. Some insects do not freeze even below ice temperature.
Pour water in a glass tube, and in another glass tube, pour water and some glycerin that exists in body of some insects in winter. Put two tubes in an ice box.
While waiting for a few minutes, let's see how honey bees feel by getting together with some friends in a nylon sheet.
You see. The water has become ice, but the one with glycerin does not freeze. After coming back to the park house, we enjoyed drawing pictures.
And, listen to what people do for rice filed in winter time.
