Solar - Radiation Zone


We've just learned about the solar core's energy, and how it's the source for the sun's light and heat.

The next part of the sun going out from the core is the radiation zone.

In this part of the sun, the energy is passed between atoms in particles called photons, over and over and it takes around 170,000 years to leave this zone!

When the sun's energy enters the radiation zone it is about 27 million degrees,
and when it leaves the zone it is about 3 thousand degrees.

Rosy Maple Moth


We just learned about the Peacock Spider.

The rosy maple moth is a very colorful and pretty insect.

It is called a maple moth because it feeds on maple trees.

These moths lay eggs on the bottom of maple leaves, where the baby caterpillars hatch and eat the leaves.
Once they are big enough, they climb to the ground, dig themselves a little cave in the dirt, then wrap themselves in their silk cocoon.
In their cocoon they transform, and climb out as a beautiful pink and yellow moth.
