Here is a model of a human heart. My daughter did this for her school science project.
Dr.Rekha Madam please see if it is proper.

Rangoli: Silk moth
Created by SuriK on 2009-03-16,

We learned about silk moths in our class. The silk moths started out as tiny brown eggs. After a few days, little caterpillars came out. These caterpillars feed on leaves. Our teacher had placed the caterpillars in a cardboard box with lots of mulberry leaves. In the next few days, they ate and got bigger. They stopped moving around and built a cocoon around themselves. Inside the cocoon, their skin started to grow and change. My teacher put each cocoon in a separate paper cup and gave each of us one to take home.

I kept my cup up on the mantle in our home. After a few days, when I was reading a book next to the mantle, I heard a faint fluttering sound. At first, I didn't know where the sound came from. But then, I noticed that it was coming from the mantle place. What a surprise, there was a white colored moth in my paper cup, next to the broken cocoon!
The silk moths don't eat anything and they are not able to fly. They only live for a few days. It was hard to see my dead moth after a few days.

Hello kids,
What kind of a rock is this? If you know what it is, please comment.
No asking mom/dad/grandparents or any of your older siblings! Smile

Rangoli: Romanesco
Created by Lata on 2009-02-12,

Hello little readers,
Have you ever eaten a Romanesco? Don't you think it looks interesting? A Romanesco is a vegetable, and is a cross between brocolli and cauliflower. Some people say that is tastes sweeter than a cauliflower. This vegetable is high in vitamin C, and can be cooked or steamed.
