Unit 4 Exploring plants

Part 1 Teaching Design

In this period, after warming up, students will first be introduced to gardening. Then they will be helped to read an exposition about plants exploration. While reading the form of the language is stressed. Three “Warming Up” designs are presented in this book for teachers’ reference. Computer and overhead projector may be used to aid the teaching and learning.

1Warming up

⑴Warming up by defining plants

We see plants every day. But what are they? Plants are a major group of living things (about 300,000 species), including familiar organisms such as trees, flowers, herbs, and ferns. Aristotle divided all living things between plants, which generally do not move or have sensory organs, and animals.

⑵Warming up by talking about different gardens ⑶Warming up by showing some different plants. 2. Pre-reading by getting to know what a garden is A garden is a planned space, usually outdoors, set aside for the display, cultivation, and enjoyment of plants and other forms of nature. The garden can incorporate both natural and man-made materials. The most common form is known as a residential garden.

Western gardens are almost universally based around plants. Zoos, which display wild animals in simulated natural habitats, were formerly called zoölogical gardens. Some traditional types of eastern gardens, such as Zen gardens, use plants sparsely or not at all.

Gardening is the activity of growing and maintaining the garden.

This work is done by an amateur or professional gardener. A gardener might also work in a non-garden setting, such as a park, a roadside embankment, or other public space.
