To all people living here:
Please do not leave bags on the ground at night. Dogs open them, and the garbage goes everywhere. If you are not sure which box to use, ask the officer at the front door.
Dear Ben,
Thank you for your letter. Life on the farm is busy. Two of our sheep had babies last week, and the little pigs are growing fast.
The river behind our house is clean again. Ten years ago a factory put poison in the water, and all the fish died. Now the water flows clear, and the turtles are back.
Come and stay with us in July. You can help me feed the animals.
Love,
Grandpa
A snail is a tiny animal with a soft body. Many snails live in gardens and near ponds. They eat green leaves at night.
Farmers do not like them, because snails can eat a whole field of young plants. Some farmers use poison to kill them, but the poison also hurts birds and fish.
Today more farmers keep ducks. The ducks eat the snails, and the farm stays clean. This way is slow, but it is safe for the environment.
Class 302 has sixty students. For one week, they put paper, bottles, cans and glass into four boxes.
| Box | Kilograms |
|---|---|
| Paper | 18 |
| Plastic bottles | 9 |
| Cans | 4 |
| Glass | 0 |
No one brought glass this week, so that box was still empty on Friday.
