3 . The world celebrates Earth Day every year on April 22. But one school in Potomac, Maryland tries to honour Earth Day every day. Very young children are learning about the environment and taking action to show their love for the Earth.

A child’s world is the world of playing. They love being outside in the open air, playing hide-and-seek, sliding and swinging on playground equipment. But children at St. James Children’s School also add to that fun by picking up rubbish in the school yard. Inside, they learn to save water and electricity. They also recycle and reuse the waste. And every spring they get the soil ready to plant flowers and vegetables in the school garden.

The children at St. James range from six weeks to six years old. The environmental study begins at age two. Rebecca Boker teaches the children the importance of taking care of the Earth. Boker says every day at St. James is Earth Day. She mentioned some books, which contain materials that ask children to do something to help the environment and protect the Earth.

At St. James, children observe the growth of plants from seeds to sprouts (新芽) in cups kept in the classroom. Then they watch the plants continue to grow after placing them in the garden.The students also observe the life cycle of insects. After that, they know it is their job to respect the Earth just like they want others to respect their home.

But do these young children really get the message that their teachers try to communicate? Ms. Boker says yes. A few days later, the kids at St. James will go out to the school garden for the yearly clean-up. But for them, Earth Day will continue for the schooldays ahead as well.
